You don't need to be good at math to become a doctor

Sixolisiwe Promise Nhlapo It’s something called “Health Class” for your supporting doctor skills that would help you a lot so why would you need to be good at mathematics if you want to be a doctor?

Wow Justin it seems you at a mathmatisian thats cool

+Justin Casar if you're proving something, you got to say where x^2 -5x+ 6 is coming from

+Wilkinson Makenstein just multiply it!!!

Pran Krishna Das He is proving something. Last time I proved something I had to say where any constituents came from and why I used them.

+Wilkinson Makenstein x^2-6x+7 is just (x-2)*(x-3)

HE SAID CALCULATOR YOU DUMB ASS

@@justno5310 The real dumb ass is you 😂😂😂

+Michiel Drost hey! Can u explain to me plz

+Ghnimi Farah , The trick explained in the video uses individual digits instead of the numeric value of the number. This means that the equation changes from; 98x97 to; (90 + 8) x (90 + 7). You can expand this further into; (9x10 + 8) x (9x10 + 7). Having said this, we can look at the trick. He says he uses a base 100 to which his numbers deviate from. The number 98 is 2 short of a 100, so we can say it's -2 away form 100. If the number was 102, it would be 2 away from a 100. That we use the - symbol is important as it tells us if we're a bit short or not. And, of course, 97 is -3 away from a 100. The trick compiles the answer back into digits. So we need to take the decimal placement into account when calculating the answer. In the video this isn't done, because you don't have to when you're using pen and paper. After all, you can write digits anywhere you want. So, lets look at the equation used in this video; 98x97=? I'm going to replace the two numbers with their own variable a and b. a = 98, b = 97. 98x97 = a x b = ab The first two digits of the answer is, 98 - 3, which is also 98 + -3. The -3 is the result of taking the number 97(which is b) and subtract the base(a 100) from it. Then we add this to 98(which is a) So, the first few digits are a + (b - 100). Note that the brackets aren't needed, but they show you what belongs to what as we reason our way through this problem. If b - 100 results in a negative number, then the + becomes - instead. This happens to be the case in our example. We also need to take decimal placement into account. The video shows us that the first digits are in the hundreds. So (a + b - 100) needs to be multiplied 100 times to get the answer in the right decimal place. We now have; 100*(a + b - 100). The next step in the trick is the find the last two digits. He explains that we get them by multiplying -2 with -3, to get 6, and then add them to the other digits. Well, -2 and -3 are the result of 98-100 and 97-100, these are multiplied together. So this becomes; (98-100)*(97-100) And now with variables; (a-100)*(b-100) This we add to our earlier found digits. I'll remove the unnessecary symbols. We now have; 100(a + b - 100) + (a - 100)(b - 100) And that's it. Thats when the trick does. Just because it's on the internet doesn't make it true. So we need to check if it's mathematically consistant. To check if ab indead equals 100(a+b-100) + (a-100)(b-100) we use some algebra. step 1: write equation ab = 100(a+b-100) + (a-100)(b-100) step 2: distribution law ab = 100a + 100b - 10000 + b(a - 100) - 100(a - 100) step 3: repeat one more time ab = 100a + 100b - 10000 + ab -100b -100a + 10000 step 4: organize variable groups ab = 100a -100a +100b -100b -10000 +10000 +ab step 5: add variable groups ab = 0a +0b +0 +ab step 6: remove unneeded math expressions ab = ab QED Since ab indead equals ab, we can say this trick works which all numbers in all cases. However, since it's based on using 100 as base, it works best if you use numbers close to 100. I hope this helps. Happy new year.

Thanks alot. It helped me Happy new year for you too

Omg this comment is bigger than me

how

But his accent is so badly

سعود العسيري Like your grammar

Tech your self first and talk about my grammar ! Smartass

سعود العسيري Ok.. you should have taught yourself first before talking about his accent

at school i always use this

what if 192*124？

Ng Tsen Zu 192 * 124 = (200 - 8) * 124 = 24 800 - 992 = 23 808 8 * 124 = 8 * (125 - 1) = 1000 - 8 = 992 Have a good day ;-)

Ng Tsen Zu man, there are technics, at 192*124 i don't know to be a techinic, only normaly 192*124

Peter Dynnyk nice 1, didn't think at it, really nice 1

+Alfred Lewis THis is better

That's how I do it.

98x56=5488 bcuz 100 minus 98 Is 2, And 100 minus 56 Is 44, so now u cross subtract. 56 minus 2 Is 54 And 98 minus 44 Is 54. And I'll say the next step in another comment

Next you must multiply the digits u used yo subtract. 44 times 2, Which equals 88. Hence the total answer Is 5488. YOUR VERY WELCOME

+Turqouise Girl does that work for this method though because im not sure how to work out what base number it is (in this case 100)

Wow

Simple, treat 98 as 100-2 and multiply both numbers by 56, that is 5600-112=5488

Wrong Turn Exactly.. I knew he is tricking us...

Pawan Gautam No, he isn't it just doesn't work with some numbers and no it doesn't have to be to 90-99.

Brain Limit 1:20 read it

Wrong Turn see my videos if u get any help form that i will be glad .

Technically, it works for all numbers under 100, but it is easy to use this trick for numbers between 90 and 99. In fact, if you know how to do multiplication for 10-19, you can calculate 80-89 fairly quickly too However, anything lower than 80 is a bit too hard since you will be doing a 2 digit multiplication on the last step, which is not very easy

. . .

your right

It worked for me

62 -38 59 -41 38*41=1558 62-41 or 59-38=21 21+15=36 3658 I got the answer

Why "21+15" ?

+Antonio Chelaru since the base is 100 we consider only 2 digits of the product. the other digits (in 10th and 100th place) are carried over and added to the sum we have calculated.

Nice then abt others numbers

In case this is a programming. It makes sense. JavaScript

It's 2

Kitty playz HE KNOWS

Chu

Sreejan Shrestha u sure?

+vinod patel It can be for all numbers under 100, but if you were to do 5*5 then you have to multiply 95 by 95, so it will be easier to only do from 99 to 90 but works for all numbers below 100

vinod patel I tried 65x87. this method is not applicable.

dane dani 65 x 87 65= 100 - 35 87= 100 - 13 65-13 = 87-35 = 52 put down 5200 because we are working with 100 35 x13=455 now 5200+455=5655 check 65×87=5655 system still works but slows down when you get smaller and smaller numbers than 100 being multiplied together.

Its for every number

+FlexBo who said it was 8556

are you stupid?

Just no.

its right

Hes Helping u To do Times and hell is a bad word

98x94, according to your theory it should be 9206, but the actual answer is 9212

+Luc Chermanne Check your math. 98 x 94 -2 ... -6 98 - 6 = 92 -2 x -6 = 12 Answer via this method: 9212.

You're right, I screwed up at some point. It works
