Dear Dolerbom, thanks for sharing your emotions. Time indeed flows so fast. I had created this video in the summer of 2007 and since then 1 million people have watched it. However I did not realise that my Math video would leave a lasting impression, someone would feel nostalgic about it. God Bless Shahryar ( Glad2teach )
As a teacher of ancient Vedic Maths and the modern Maths I can tell you that both the Western and Indian Methods can peacefully coexist. Vedic Maths is designed more towards the speed (mental) and the western system is more theoratical (more steps involved thus more systematic). Learn both and become smart at Mathematics.

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. I salute you. We must love Vedic Math. I am so glad there are people like you keeping it alive. It makes me so proud to be Indian. Keep it up, and try to teach it to as many people as you possibly can. I just wish people would share many other aspects of our great Indian heritage so freely with the world.
Dear Beeandhoney, yes I am a Math teacher. I feel supremely honoured when people leave such sweet comments like you have. Teaching is indeed a noble profession. From my long experience of being a student and then a teacher I can tell you " To teach is to learn twice ". You get better every time.
This method blew my mind, I cant believe it actually worked! I memorized the times table when I was a kid, but I couldn't do long multiplication in my head because of how many equations I had to do. With this method I only have to do 3 equations in my head, it's so much easier. I'm still shocked how much easier this is, this is INSANE.
this is a nice trick. I wanted to make sure it works in all cases, so I translated the trick into math and I get: ab = 100*(a+b-100) + (a-100)(b-100) ab = 100a +100b - 10000 + ab - 100a - 100b + 10000 ab = ab seems good to me. cheers
+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.

In the second its even easiee, because its basically 9500 - 95 = (1 unit deducted as if you multiply by 100). By 98 will be -190 = 9310, and so on. etc etc.
This method does invariably work. What he's effectively saying is this: Let A and B be two numbers less than 100 and let An = 100 - A and Bn = 100 - B. Then A* B = (100 - An) *(100 - Bn) = 100*100 - 100*Bn - 100*An + An*Bn = 100(100 - Bn) - 100*An + An*Bn = 100*B - 100*An + An*Bn = 100(B-An) + An*Bn. Since both A and B are less than 100, 100(B-An) is a number less than or equal to 9800, that's why he places the result of 100(B-An) as the two most significant digits. Since A and B are symmetrical, you also have A*B = 100(A-Bn) + An*Bn.
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
+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.
sir, just i want to say that aweeeeeeeeesome👌👌👌👌👌these tricks will very helped for meeeeee for my pre medical exam..... thanks u sir...i want to these type of more mathematical tricks..
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
+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
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.
This is where this method comes from: 98 x 97 = (100 - 2) x (100 - 3) ==> This is where the -2 and -3 comes from! = 100 x 100 - 3 x 100 - 2 x 100 + 2 x 3 Note: -2 x -3 = 2 x 3. Factor 100, our "base" in this problem, from the first three terms: = 100 x (100 - 3 - 2) + 2 x 3 = 100 x (100 - 2 - 3) + 2 x 3 This last one seems obvious and may even seem pointless at first but I wrote this out to show the method. We can either do 98 - 3 or 97 - 2 to obtain 95 and this is because it doesn't matter whether we subtract 2 or 3 first from 100. Get this? = 95 x 100 + 2 x 3 = 9,500 + 6 = 9,506 I like using these "base" shortcuts. After some practice you can start to do these pretty fast! You are free to pick a base that is convenient for the problem. A base of 100 was convenient for this problem. Enjoy!
Is there a way to simplify the math when the numbers aren't in the 90's? For example: 63x 47 you end up having to multiply 37x53 which defeats the purpose to begin with.
But what if there's a number 24 or 23 will this formula work too then we must think our base first and it will not work in 5 sec so pks make a video of my question

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.

This method does invariably work.
What he's effectively saying is this:
Let A and B be two numbers less than 100 and let An = 100 - A and Bn = 100 - B. Then
A* B = (100 - An) *(100 - Bn) = 100*100 - 100*Bn - 100*An + An*Bn = 100(100 - Bn) - 100*An + An*Bn = 100*B - 100*An + An*Bn = 100(B-An) + An*Bn.
Since both A and B are less than 100, 100(B-An) is a number less than or equal to 9800, that's why he places the result of 100(B-An) as the two most significant digits.
Since A and B are symmetrical, you also have A*B = 100(A-Bn) + An*Bn.

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)

Easy:

what if 192*124？

is it only for 90 to 99
+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

I thought this is called VEDIC mathematics
guys this only works easily when it is between 90 and 100
fantastic tricks Sir
thats why i hate maths
math is the best thing ever I love math..... I wish math was a person I would hug him until he is dead
Natnael turn :) me too
Natnael turn i hate maths as well -_-
everyone hates maths except for maths teachers
Ethan Goeske No, most teachers act like they like it but they usually become a teacher for the money...
What the hell
Hes Helping u To do Times and hell is a bad word
Thankyou sir❤️
this only work from 91 to 99.
i was thinking same, u r ri8
Yeah, he said numbers naire 100
calculators are much faster...
How you do 57×38= ?
Hey thanks it's a great technique for calculating the no within a seconds,great job......
very nice, i wanna know what's the software or like that something... in which you wrote with the pencil or anything else
Thanks
Thank you for the math trick you have showed us.
This is so cool.
For those of us who have been told to be bad at math this is such a badass thing to master.
This is where this method comes from:
98 x 97 = (100 - 2) x (100 - 3) ==> This is where the -2 and -3 comes from!
= 100 x 100 - 3 x 100 - 2 x 100 + 2 x 3
Note: -2 x -3 = 2 x 3.
Factor 100, our "base" in this problem, from the first three terms:
= 100 x (100 - 3 - 2) + 2 x 3
= 100 x (100 - 2 - 3) + 2 x 3
This last one seems obvious and may even seem pointless at first but I wrote this out to show the method. We can either do 98 - 3 or 97 - 2 to obtain 95 and this is because it doesn't matter whether we subtract 2 or 3 first from 100. Get this?
= 95 x 100 + 2 x 3
= 9,500 + 6 = 9,506
I like using these "base" shortcuts. After some practice you can start to do these pretty fast! You are free to pick a base that is convenient for the problem. A base of 100 was convenient for this problem.
Enjoy!
Is there a way to simplify the math when the numbers aren't in the 90's? For example: 63x 47 you end up having to multiply 37x53 which defeats the purpose to begin with.
My new favorite math teacher!
I learned more from this 1 video in a few minutes than I did in school in 1 week
this'll be a big help on the asvab
this is a great method for calculating numbers in the tens
Wow. I can't wait to tell my calculator he is getting a promotion
Thank you so much for your awesome channel !
I bet my teacher is going to give me 20 bucks for this Trick
This guy: I can teach anyone math me: let me introduce myself
Good trick to multiply numbers in a easy way
bro i thought this was fake like most other videos but then i tried it but it actually worked thanks man
Omg thank you so much easily if I see number less then 100 I will do it
Yes
Wow thank you so much bless you
I love your video because it easy to understand than the other calculated
Just subscribed! Thanks for this. Amazing video
nice trick to do it buddy ! but can you tell me from where did you find that trick ? no seriously i want to know it buddy ?
How did you get the 100
Where was this when I was in school? :(
It did work for that number, but when I tried another number it didn’t
man you're math genius,would you please teach me how you do?
finally something helpful. thanks for not filling youtube with crap
Hey dude. You've got awesome video. Big thumbs up for! Keep it up.
Super cool i love your trick thank you so much keep up the good work
Omg...learning something every day. Love it!😀
Please publish some videos on ages of ratio
its a vedic maths trick this techqnique is being discovered in INDIA from many ancient period really my india is the greatest
But what if there's a number 24 or 23 will this formula work too then we must think our base first and it will not work in 5 sec so pks make a video of my question
that was cool sir....wish u be my math teacher....
