Dear Dico for mentally doing 23^2 use the Base20. See the 3rd vid on Glad2teach website (link given below the vid above) 23 is at the distance of 3 from Base20 ( pls note that this distance 3 would be added initially and later its square would get added) Here I go step by step Step1: Add that 3 to 23. You get 26 (or 260) 0 indicates that one more place to go. Step2: Now double up 260 and add to it square of that distance 3 (that is 9) 520 + 9 = 529 (ANSWER) Shahryar (Glad2teach)

Drew2pac, thanks for adding your valuable comment !! Once again let me emphasise that knowledge is a Collective Heritage of our entire "Human" Race. As an Indian I am proud of what my Indian Ancestors have achieved but not in an arrogant manner. I am trying to make my own humble contribution to this ocean of knowledge on Mathematics. Rgds Shahryar (Glad2teach )

@DanandDonna1 , thanks for pouring your heart out while writing your comment. Math if learnt the right way fills you with pure excitement and tranquility at the very same time. I wish to take you and other people who are struggling with Mathematics into the magical world of numbers. A guided tour till Infinity and back. Once the human mind gets the real taste of Mathematics then it keeps craving for more. Math is the workout for your brain ... it is addictive .

and become a hero on class

Dear math teacher, I love your youtube videos. I'm really grateful someone like you exists out there and is willing to share his knowledge with others. Thank you !

Dear Chamillionaire993, I use just 2 EasyCal techniques to perform all my multiplication mentally. 1) Base Multiplication 2) Rainbow Multiplication If the given number is far from any Base then of course you need to use Rainbow Multiplication. See the Video Response I have attached below. Incidently I was given the number 67 to multiply mentally in a Live Seminar ( see the video below ) Shahryar (Glad2teach)

It is been three years i have been as your fan..Satisfy and friendly Hats off you

Stefan, 116 square can easily be calculated with Base Method I have shown above. 116 is at the distance of 16 from our base100. So 116 + 16 = 132 _ _ ( two more places to go) or 13200 Now we just need to put the square of 16 in those empty places ( in case you do not know then you can use base10 to calculate it to be 256 ) So 13200 + 256 = 13456 ( Final Answer) Watch 3rd EasyCal video on Glad2teach site to learn this Base Method (link given below the video above) Shahryar (G2t)

You should have ended the video with: "Thank you, come again!"

This is AMAZING! Thank you , thank you, thank you!! This is going to help me out in my GCSE's and in general life so so much! :D

Glad that you liked this Easycal techniques ( from ancient Vedic Math of India ). This technique is called Base Multiplication. "Base" is a friendly number whose reference we take to multiply the unfriendly numbers close to it. Usually the powers of 10 make a good base ( like 10, 100, 1000, 10000 .... ) and so do some multiples of 10. To learn how to use easily other bases watch the 3rd EasyCal video on Glad2teach website ( link given below the video above ) Shahryar (Glad2teach)

I was looking for few videos for fast calculation. I am happy that Glad2teach is one among them. One thing I liked the most is the emphasis given on the word mentally.You guys meant it and stood by it. There are other crap videos who show complex methods and calculating in their method requires pen paper.I am interested for methods where I do everything mentally. Keep it up!!!

that was sick! now I will show my friends about it and they will be super amazed

or You can Do it with the binomic formal : 104^2 (100+4)^2 100^2+2*100*4+4^2

Dear eyeliner12sd, you have made a great start in Mathematics. Keep this momentum of learning going by regular practice. Soon you would become fluent with numbers. All the Best Shahryar ( Glad2teach )

I have always struggled with and been intimidate by math. This video has eased my anxiety and I am eager to learn and strengthen my math skills. Thank you so very much!

This is somewhat useful, but it becomes utterly pointless when your numbers go beyong the twenties below or above the 100 mark, as it requires increasingly difficult head multiplication. Not to mention it doesn't work for numbers below the 50 mark.

genius!

Dear hammas74, to see how to square the numbers near Base 50, see the 2nd video on Glad2teach website ( link below the video above ). 45^2 45 is at a distance of (minus) 5 from Base 50. So subtract that from 25, you get 20 _ _ ( you get first two Answer digits ) Now for the last 2 Answer digits, simple write the square of that distance (minus) 5 That is 25 So the final Answer of 45^2 = 2025 ( Ins't that easy !! ) Shahryar ( Glad2teach )

@wackyLegends , You got it right !! That extra 0 comes as for 1004 the Base is 1000 ( it has 3 zeros thus 3 places to go )

if da number, like previous comment, does range from 20-89, what do u do

omg thank you so much for this! amazing

You're videos are very helpful! Thank you for posting them! I wish I knew this stuff when I was in school so I would've had less homework and more play time! I am going to show your videos to my kids! Thanks again!

ky eshte nje ushqim per truri.faleminderit

ur all the tricks are awesome and so easy but caN U ALSO GIVE ME A TRICK to remember all the trick for different sums

I was like 1016 no wait 10016 FUUUUUUUUUUUUUUUUUUUUUUUU

Thanks !! If one is really keen to acquire knowledge then all the hurdles can be overcome. All the Best - Shahryar ( Glad2teach )

Thanks for making math so simple. I wish I knew these tricks in high school. You are great!!! Keep posting!!!

I did 103. So I did 103+3=106. So first 3 numbers is 106. Then 3^2 = 9 then I got 1069 as my answer, but it was actually 10609. Help please

Thank you so much does these videos! I've showed them to everyone!!!

i love your enthusiasm for math. This subject I can never understand and never will. Parents didn't care much to help and when one of my parents tried to help, she ended up screaming her head off, day after day because I don't GET it. Asked teachers and was lucky to get a minute with them. The school system failed me back then, 40yrs. ago, and doing worse now. That's where it lies.

Simply amazing. i really wish they had videos like these when i was growing up. Thank you!

why have stopped publishing the videos. All tricks are awesome. Please upload more

I like these and the way of teaching is so nice. thank you

I found one to share with you since you're so good at these.

Thanks for keeping the discussion erudite Ancient works of India I have referred to above were in Sanskrit (one of the oldest Languages). These books were translated in Arabic by great Arab Scholars like Khwārizmī (aka Algoritmi) & Al-Biruni which were then translated into Latin (English) These Arab Scholars gave credit where it belonged & called it Al-Arqam Al-Hind meaning Numerals of India. Great Fibonacci called it Modus-Indorum (Methods of India) in his famous book Liber Abaci Glad2teach

You Sir, are amazing! I have a maths exam tomorrow, I'm sure these methods will come in handy and save me lots of time!! Thank you.

hello glad2teach... please upload more videos... i love all your lessons...

That is amazing. Sick method as well

Thanks for taking the time to post.

It does work and it is very easy !! Use the right base (Base50). See the 2nd EasyCal video on glad2teach website ( link below the video above )

You should use Base50 to square or multiply any number near 50. See the 2nd EasyCal video on Glad2teach website (direct link given below the video above). Shahryar Badar Khan(Glad2teach)

Thanks for the trick! Super helpful

Thanks for your kind advice !! Shahryar (Glad2teach)

Glad to learn. Thanks a lot for sharing

Wish i had known these math tricks yrs ago!! I'll be able to use them. TY so very much!!

simply genius man... mazaa aa gaya!!!

Love his ascent! :3

Knowledge is a collective heritage. 5000 years old Indus Valley Civilization (ancient India) has made remarkable contributions to this pool. 1) Hindu Numerals (our 10 digits from 0 to 9 ). No modern Math could be possible without them 2) Decimal Place Value System (Base 10). As you know Roman Counting was not Place Value thus highly difficult. 3) Pingala first used Binary System (Base 2). Without this there would have been no modern computing. No word limit left. Shahryar (Glad2teach)

Wow I think this trick is fantastic. Thanks for showing it to me

There's another video posted for #'s 30-70. Same idea, but your base# is 50 instead of 100. Find the distance of the # from 50 ie: 40. 40 is 10 less than 50 so subtract 10 from 25 (1/2 of 50) and that is your first 2 digits (15) then find the root of that distance 10^2 =100 ....so 00 are the last 2 digits the 1 gets added to the 2nd digit 5 making the answer 1600!

Very interesting trick sir thank you so much for solving fast method

wow ur videos are so simple and awesome i love ur videos :) btw i subscribed :)

CharlesIddesleigh, thanks for expressing your kind gratitude. 'Thank You' goes a long way. You should watch all the EasyCal videos on this KZfaq channel and also there are 3 more free vids on glad2teach website (link given below the video above). You can build a strong foundation in fast Math. There is a paid tutorial as well ( full EasyCal Series on faster Arithmetic & Algebra) if you later become keen to take your skills to the next level. Best Wishes Shahryar Badar Khan (Glad2teach)

This is an application of the formula (a+b)^2 = a^2 + 2ab + b^2. We just do 104^2 = (100 + 4)^2 = 10000 + 2*400 + 16. A similar example is 49^2 = (50 - 1)^2 = 2500 - 100 + 1 = 2401. Numbers closer to 100 work well because how well they fall into place.

Thanks for this video I am confuse in when mam teach the square but when I see your video clearly I explained thanks

Amazing, i wish i had this back in high school

thank u very much, will be applying these tricks,

found this interesting. i wish you would go more into detail. for instance numbers below 50. I tried applying your method and it was confusing for numbers under 50. as far as the 100 being the base, i get that and that is awesome. i would just like to see more examples.

Love your videos!!!!!!!!!!!!!

Awesomeee...... beyond my expectation... I never thought dat it is as easy as u teach...... thank u sir.....

I love your work this is great stuff. I want to to some video teachings myself and I am using paint but I like how your stuff looks. What program are you using and are you using a tablet to write?

Leisure Math !! ... I liked that terminology. Shahryar (Glad2teach)

thankyou so much I m loving this

Wahoo it is a nice nd fast way . U r superb sir ji 😊😊

Thank You For The Great Job

This is amazing. Thanx.

love your video!

Ur awsome man!!!!!i freaking luv ur videos!!!!!pls meake more of 'em dude!!!!!! u totally rock!!!!!

Thank you sir, it is really helpful for faster calculation.

LOVE IT!!

The title of the video says everything: it is about tricks, a kind of heuristics that you can use to solve real-world problems. Hence, they are quite useful - I can't think why someone would waste his/her time to attack a video like this! Our friend Shahryar is doing a good job by teaching these techniques for us!!

that is owesome! thank u so much for teaching us

@glad2teach i second that .... math is addictive when you understand it and you want more out of it. Also, TEACHING math is another one of my addictions!! Thanks so much for all the shortcuts!!! keep them coming :-P

This is great! Thank you!

awesome!! thanks a lot

Cool video, thank you!

thank you so much,you helped me a lot

THAT WAS REALLY AWESOME.

It's very amazing easy way to calculate fast , thank you very much :)

Having to bone up on my math. My son is going into AP this year and I'm afraid I won't be able to keep up / help him much longer. Thanks for the help!

thanks,this was helpful!

sooooo great make more teach me all the quick ways u are a boss

this really helped, thanks. You have earned a sub.

thanks sir..superb trick

AMAZING!

glad2teach.. i really admire your math-tricks.. i am a mathstudent and since I learnd your tricks I can calculate faster than my professor :D

You're awesome; thanks!

Wow this is an amazing tip! Thanks alot! :)

Good question !! Because it is the distance of Base that counts. 112 is at the distance of 12 ( not 2 ) from 100 . Shahryar

Thank You very much smart and easy way ............ thanks alot

Can you use the Japanese Multiplication method in these? Thanks.

awesome, great trick, makes me wonder about some things...

i love the tricks :))

superb sir.sir i want to learn basic fundamentals of maths like trignometry and calculus also.please suggest me what should i do

Thanks man!

Most viewed video of your and thanks again for teaching me new math

you video is very.very,very,very,very,very,very,very thankful. i can not give my happiness by this. my whole class and friend amazed by this

Thank you so much! You're the best :)

Very quick and awesome
