Why am I watching a calculator speed test I should be doing homework

TWO points that you missed. 1) The HP advanced graphing app is an IMPLICIT plotter, thus you can plot an equation in open form ( sin(x*y) = x^2 ) whereas on the TI you could never plot such a graph because it has to be in closed form ( y = ). I cannot overstate how much of a huge advantage this is over the TI. 2) Whatever person chose to put the letters and certain symbols on the the HP Prime White Keys in ORANGE should be FIRED !!! They are very hard to make out in various lighting conditions. Incidentally, I have all three ( HP Prime, Nspire CX II CAS, and the FX-CG500 ) love them all and enjoy using them.

I really like that you are covering a niche topic, and doing so thoroughly and in depth. Your review really has a lot of substance.

Awesome review. I would say I definitely prefer the HP Prime in terms of speed of processing commands, the ability to adjust the graphing window quickly with the touchscreen, and the library of built-in functions is much more robust, and I prefer the TI Nspire for its full keyboard and ease of creating functions on-the-fly. I will say that what the Prime lacks in descriptions of its error messages it makes up for with its substantial Help feature for every built-in function. For deciding on one or the other, it mostly depends on what it will be used for. The HP Prime is probably geared towards more advanced mathematics while the TI calcs seem to be made more for the high school and early college students. I wouldn't say either is particularly great for programming, since even with a full keyboard it's sort of a pain with the TI Nspire, and I prefer coding the programs on an actual PC and transferring them to the calculator, but it's basically impossible to do it with the HP Prime's lack of a keyboard. Side note: The HP Prime actually does have a partial derivatives template located under the templates key (the one located to the right of the toolbox button).

Very nice video, I had a similar opinion when I reviewed the HP Prime G2 myself! The production quality looks great, keep it up!

I really like the design and functionality of non-TI calculators but it's super annoying to try to figure out how to do certain things in class when the professor is using a TI.

I’ve always used the Texas Instrument calculators and never considered anything else but this video has me second guessing my loyalty! Right now I have lots of programs and tools built around TIs but I have lots to consider! Thanks for the comparison!

Thanks so much! I went through college with my TI89 (before Titanium) and I loved it. Now I need a new calculator, and I've been leaning hard towards the TI-nspire, but not anymore.

This was a very helpful comparison. I have always thought HP was better built than TI and you confirmed my belief. Thanks.

Really nice and precise review. Did a great job comparing displays for example, that the one one in TI sits much higher. Even Smart Phone reviewers don't put that much effort and precision about things like that. The math functions comparing was also good.

This reviewer is absolutely right in his assessment. I am an older professional mechanical engineer, and recently I thought I should better refresh my rusty maths, as well as getting familiar with these newer maths tools. I bought all three (TI nspire CAS, HP Prime G2 and Casio fx CG 500) and I can confirm that HP appears way better built than the other. I actually like the TI quite a lot, especially when with all the alpha keys you can enter directly the functions and operators easily (as well as having way more tutorials and learning materials. But the overall first impression is that long term I will focus on the HP which seems to be better built and more professional (as opposed as just a school teaching device). It is still very early stages for me, and things may change.

Nice comparison! I was surprised by this iteration in the Texas Instruments line-up. The processor speed variance is significant and the touch screen and resolution of the HP looked way better. The document system in the TI appears to be very "clunky". A few things you didn't touch on was the pc/computer interface between the calculators, what programming languages (python is currently supported on the TI as opposed to the HP's Prime Programming Language (PPL)) each calculator supports and any accessories or add-on each have which you could do in a later video or update this one and how those things might affect a person's decision.

Very useful comparison, thank you. These models are significantly faster than the Casio fx-9860GII that I use.

Thanks so much for an excellent video, which led me to purchase the HP from eBay for a reasonable price. I've owned the TI-nSpire for a number of years and it has spent most of its time collecting dust and losing charge. When I did use it, I found it to be so cumbersome. I spent some time following a tutorial to learn the features and found the overall human factors engineering was terrible. I'm delighted to come across this HP prime comparison video, which shows how easy the HP is to use. I was shocked to see how much slower the TI is than the HP. Just for curiosity sake, I programmed that summation into a few lines of BASIC in my own written BASIC interpreter. I designed and programmed the expression evaluator, which, internally uses RPN. The interpreter executes many lines of C code for the operation. I am pleased to say that that same perceived speed on the interpreter is instantaneous. Of course, I am using it on a fairly new PC. One of the most difficult things to do on the TI is to scale a graph down to see more of it. The use of the visual hand grabber is a challenge.

nice video. going to get the HP. had one in college in the 90's and miss it!

Excellent review! Thanks for sharing. Over 30 years of being a teacher at a University in Mexico, I had been using TI for over 15 years, after HP almost leave this market (I used de HP 48 and 49 at the beginning of the 90s) and I was very happy with TI (I am retired now). I really liked the use of documents, the sheet classes, the programming style, the primitive functions about probability distributions, the inclusion of LUA and now Python programs, the emulator software, and the easy way to share documents (some of my students make documents for each homework or exam). The "solve" command in TI surprised me when I was looking for a limit in a definite integral in an arc length formula. And maybe the most important thing is the TI community, which is very active in some countries, particularly in Australia. I really hope HP company will think the CAS calculator market at the college level is important. Again. Thanks!!

Thanks for the Review man. It was very helpful.

Awesome comparison! Great video!

A superb, insightful review, many thanks!

Really like this review! I honestly feel like a good graphing calculator should have most used dedicated keys for trig functions, logs, exponents, etc available without being forced to look for them in sub menus ...I have been using my old HS calculator TI 83 Plus but am really impressed by HP Prime! The ability to just punch on the screen to zoom on the graph....wow!

I checked a couple of the other reviews and yours is by far the best, thanks for touching on hardware and build issues. Seems the TI supports Python scripting but given how underpowered it is, I’m not going to hold my breath. Ordered the HP. Thanks!

Thank you. Great video clip.

Well you can create documents with HP Prime. It is just that they do not call it document. In the Apps menu there is a Save button which is in my opinion the exact same function as documents.

Nice comparison. I used to be an avid HP48 user through college. I didn't do enough research and just bought the Nspire CX II CAS. I agree with you on all points. I hate going thru menus and 2nd order keys for EE, etc. Keys are tiny and cheap feeling. It's an extremely capable device, but all your points are exactly what I missed about my old HPs. The old HPs were SO SLOW...even for the day. But the input and so fast and well laid oout. I may cut my losses and get the HP and give this to my son.

Great comparison! I would add that when it comes to doing any matrix operations, the HP beats the snot out of the TI. The toolbox on the top row gives you access to all of it.

That review nails it for me. I was seriously considering buying one other the other but the HP is a clear winner.

Excellent comparison, and good reasons for using the hp .

thanks - clear explanation of the differences

This video actually helped pick the calculator I'm going to use for high school, HP prime all the way!

Thanks for your amazing explanation. I was confused on what to pick, but of what you've illustrated, HP Prime is much better, I wonder if we can compare HP Prime vs Casio fx-CG500. But really thanks a lot for your video.

My first HP was the 15c and I loved that lil bugger. I’ve always loved HP calculators, however, I have used other brands as well and I have enjoyed them too.

I had my first HP calculator 47 years ago - the predecessor to the HP45. That calculator was a basic scientific calculator that used HPs RPN notation. It used the same keys as the current Prime and lasted many years. I upgraded to the programmable HP29C and eventually to the HP41CX. All were great for their time. I am currently using the TI84 because I work with high school math students, who use the TI -- but I certainly prefer the HP platforms. I wasn't aware of the CAS and will look into it. I have currently been using Mathematica online - which obviously has much more computational capabilities.

Just a note. I think that is brushed aluminum on the front of the Prime, not all plastic. ;-)

Nice comparison!

I am also a professional and needed a calculator that didn't involve more computer use, more versatile, so I chose the ti nspire. Definitely not disappointed. I bet the HP is good as well.

Good video. I'm not sure if you notice the slightly different results in the sum calculations between the HP and TI starting at 7min. 20sec. mark. The 4th decimal place and onwards are different for HP and TI. I'm curious to know if you would write a simple program to independently verify the value using double-precision or quad-precision calculations. Thank you.

I just tried your sum benchmark on several other calculators. Both of your calculators are blazing fast in comparison. :D

Are you planning on really detailed HP Prime vs Casio fx-cg50? That kind of video is really rare.....

Most important thing as someone who got his electrical engineering degree in ‘89 ( think HP41CX and after working a bit, the HP 48GX, my personal favorite), the HP does RPN, a must!!

Tough choice, personally I like the physical key layout on the TI (lettered keys). If you every had to translate real world functions into a calc it is way easier to use the actual variable starting initial than have to back translate x, y, z, t variables for respectively a kv value or delta P, etc. Torn. Yes you can do that with the Prime, Rs and other letters, but the TI has is down for high level work. Note: the trig button is way better like this, having the ti-89, you are always looking for the dedicated sine, etc button this has it in one place. Personally, this is way better thought out in terms of layout.

Can I programme any function or a set of instructions in HP Prime?

Very good work. Thank you.

The original clickpad nspire had the alphabet keys in between the normal number keys but they do stick out further than the normal keys which creates accidental keypresses but sin cos and tan have their own dedicated buttons and the number keys feel in a much more natural place. Also the normal keys have this cool shape because of the alphabet keys in between

Now I know to save a few bucks and go with the HP Prime G2 instead of the Nspire CX2 CAS.

Great review many thx. Pls can you help. I am considering buying the ti cx2 cas but am held back by what i understand to be the only way to enter x, y, and z as variables. The ti famously has a full a to z keyboard below the central number keys. Ok some want that freedom of direct entry. But v heavily we are con erned only with the entry of a single letter as a variable, that is x, and possibly a y or z as a second. But the only placement of the x y z keys I see is at the extreme bottom of the keyboard. Would that not mean that as numbers are entered into the display the hand must make a jump of three inches down to select with difficulty the often needed x letter to input into the screen? Pls is there a another x key close close to the central number keys or another fluid way of inputting an x variable? Good day and thank you.

Great review!

If you think that navigating through the menus is annoying (TI), for example if you need the SIN function, you can always type "sin" with the extended keyboard... That's why there's a keyboard and a sin button is not available...

Yeah! Like Jean Edouard I am asking : what about the g2 ?

Please do a comparison on HP Prime and Casio fx-CG500

How would someone do a function like say...input a formula into a column to apply into the next column. for example D2=D2^2 to make it actually calculate without giving an error message in 1 var stats?

I want to get one of these just to make my basic Algebra and Electronics classes more entertaining and fun.

I was also thinking about these two products, and I think it helped a lot. Maybe I should decide on hp. Do you still think hp is better?

Should it have a slide rule mode ? In case verification needed on complex function

Can the HP prime save long calculation files or test calculations for later use or editing? I think if he doesn't, it would be a great weakness against Texas.

Been using HP, TI, and Casio forever and recently picked up a used nSpire for fun. It is definitely a classroom tool. Annoyingly so. I don't think anyone outside of acedamia would prefer it over the HP.

I have both a Prime and an nspire, and have barely used the TI. My experiences with them mirror Math Class Calculator's. I do like my Prime, my favorite calculator yet, and I have some dating back to 1981 (HP 11C).

AFAIK CAS can be disabled in the TI, otherwise it wouldn't be certified for certain tests, you probably have to go through some menus to do that. As per the keyboard well this is more like an all-round Calculator, a whole ecosystem for STEM which includes programming for which a full keyboard can come in handy. Anyway it was a great review maybe the HP is better for field trips where you just need the calculation ASAP and not just the other features, maybe they can complement each other.

good,,, pls suggest which machine can do indefinite triple integrals

I had to get the cas ii cas because I got so used to the keypad layout with the abc keyboard. (You can use ctrl + a to select all, ctrl + c to copy, ctrl + v to paste) I also have a hp prime graphing calculator. I'm probably going to be using that one for graphs and the cas for functions and the cas part since I am so used to the layout because of the first one

if you have time could you make a video for the HP Prime covering the Solv functionality? It does not seem to be consistent. For example, xTheta will provide a "a" or and "x", I would like to think it is the difference between CAS and Non CAS mode but I have seen an "x" appear in both modes. It just seems quite finicky compared to the TI NSpire which does a really good job of solving whatever you enter due to it's "AUTO" mode of operation switching between CAS and Non CAS operations on the fly. And why can you be in solve app then enter a solv function, modes of solv operations is confusing. Thoughts?

For the developing of engineering apps what would you suggest?

I have the Ti89 for 16 years and never had a problem and the keys wobbles since 1st day. You can have some keys that never wobbles and can stop working after a while. The question one should ask is ….. will it last ?

很好的视频，你让我放弃了购买TI，本来我还以为贵一点会好一点

Do the calculators give you the procedure of mathematical operations?

I just receive my nspire cx II cas and it’s amazinggggg

The calc test @5:58 took 16.57918 minutes on my HP 48G. (time corrected)

Is this the HP Prime G2 version that you have?

I'm glad I watched this but wished I didn't. I own (ti-89 titanium, nspire cx cas and nspire cx ii cas). Never considered the HP until now. I come from using a ti-36 and a pencil to these machines. I'm in awe of what they can do. HP needs to cut you a check. Good job on your review.

Does the HP Prime Graphing Calculator Ii have features for Differential Equations ,Linear Algebra, Physics, Electrical and Mechanical Engineering. PS you have a great presentation

Casio fx-CG500 vs HP Prime, which one is the best?

How do you access the periodic table on the HP Prime ?

Useful! Thanks.

Thanks!! I love this comparison... Can you compare a symbolic definite integral, like $\int_0^\infty e^{-x^2} dx$, in both calculator? I think HP Prime is superior to TI nspire here... (I apologize for my english, it's not my native language)

7:39 which one gives the right answer? They are different.

The perfect calculator would be a combination of the best features of both. That is why understand when some people wrote they'd buy both. It had been great if CASIO fx-CG500 had been included in the comparison.

I would like to see a video on storing electronics equations like for resonance,xc,xl, etc. I bought a HP27s in 1988 and it just died 4 days ago and that calculator made it so easy to put complete formulas with letter titles. You could solve for any of the variables easy. This was way ahead of it's time and too bad it didn't become a permanent part of HP's line up. This is my reason for requesting a video of how you can store electronic formulas which would give me the confidance in buying one. Otherwise I'll just buy used HP27s's off ebay, thanks.

How about HP Prime vs Casio fx CG50 ?

Did they stop making the HP prime? For some reason there aren’t many sellers selling it new and the price is up around $130

can you do a video on python comparison between these 2?

My first calculator was in the mid 70's a sears electronic slide rule with 40 functions and a memory! all for only 80 mid 70's dollars.

I have and use both. Good assessment. The Prime (G2) is sweet to touch and manipulate for graphs, the nspire easier for keyboard programming on the go. They're both worlds away from my 40 year old HP15C (still a marvelous tool in its own right) and my TI-66 (glacially slow, but capable).

You are not being nit-picky; TI has always tried various keyboard layout system, which is yet to match the original Ti-83. Remember the Ti-92? While if felt like a cool gaming system, I still preferred the hp48GX system back in the days. Perhaps the attempt is to squeeze it all into a standard form factor. The thing is that they all got it right the first time as calculator where not really designed around the QWERTY key layout; I could type as fast on the chronological keys. Oh how I wish the hp had retained RPL programming though. Nothing comes close to that to date. Great video by the way. I always loved the calculator for their differences, and offcourse accepted the limitations. The Ti-85 took a bit further in the string manipulations; however, it was still no where close to the hp, without jumping into machine programming. Though they did their things in the past, and lead the way before the smart devices, such as windows, palm, sybain and android. I still wonder the future of calculator. The main idea is to be simple yet intuitive and sophisticated as needed.

Its there a handheld calculator that does show the steps?

10:15-11:00 of the video I think is one reason why the TI-Nspire is the better, more expensive calculator. The fact that it does Numerical Analysis and Differential Equations is huge, although the HP has the ODE solver but that's not enough DE. The TI's python is a more sufficient way to programming. Also, I didn't see Prob & Stats on the HP but I'm sure it's capable since the basic TI-83 can do it. I'd say that for everyday use, the HP is good since it's really fast, but the TI has more ability and is a necessity.

I do not care for the track pad on the TI either. It looks a little weird, but with a USB A female to USB mini male adapter you can hook up a mouse to the TI and use that instead. It makes working with the calculator a lot easier. If you do this, be sure to get a "mini" adapter and not the more common "micro" adapter.

The HP seems the clear winner although I prefer the font & display layout of the TI. HP just needs a "prettyfy" routine to make expressions look nicer (e.g. italic letters for variables) like Casio does.

Funny how HP Prime feels like a modern competitor to the Nspire while taking some design ques from the Ti-8x calculators via the buttons. Best of Both worlds in one. I wonder if HP Prime has a Word Processor like how the Nspire has. (Better question is why Nspire even has Word Processor and Spreadsheets)

I just run the sum in Maxima and appears to agree with the ti's result. Can anyone confirm if that is the more accura result using any other software? I don't have easy access to anything else at the moment.

What is the main difference between TI-nspire cx ii cas and TI-nspire cx-ii t cas?

what is your opinion on Casio 991-EX ?

Juemadre gracias, me voy a comprar la hp prime :)

HP PRIME 👍👍👍👍👍👍👍

HP made the first programmable calculator and very formadable could non touch key may help

I have both the HP Prime G2 and TI nspire CX II-T CAS. Personally, I get on better with the HP. I find it much easier and more logical to use. Working with it is also much smoother, because the TI generally works much slower. The battery life is really better with the TI. Especially if you haven't used both calculators for a long time. The HP is nevertheless empty after 3 weeks (so when you come back from holiday, always remember to recharge). The TI can be left unused for 2 months without any problems, but the battery is still only minimally discharged (the TI seems to have a deep stand-by mode, because it has to reboot first). I would still buy the HP Prime again and again. For me personally, it has the best overall concept (also with regard to the software for the PC).

I had an HP48G back in the day. Everything was done in 'reverse polish'. Eg. 100/2=5 was done by entering 100 2 divide. Is this the method of operation for the HP Prime?

Thanks!

At 13:30 - i type it in WITHOUT the multiplication sign on my hp prime and it replaces it just like the Nspire. Maybe you need a FW update? I have SW 2.1.14603 (2021 12 02), HW version D, CAS version 1.5.0, OS V2.060.650

I have no experience with graphing calculators, but I just finished a year of multivariable (vector) calculus and would like to know if I can use the HP Prime for multivariable calculus graphing? 3D graphing of solids and 2 D surfaces and vector equations? I would think these would be no problem, but don't know. For example, a plane intersecting a cylinder?

Which one is better from these two calculators??

It would be helpful to know what hardware version of the prime you are using since there are atleast three.
