I watched the video, then i did a Multiplication test and my teacher was shocked and thought that i was cheating on it but i wasn't, and my teacher thinks i'm a genius but i owe it all to glad2teach thanks very much!
Actually, it does. 1: 86x26 8x2=16 & 6x6=36 ,so for now, the number is 1636. Now after we do the rainbow multiplication, we get (8x6=48) + (6x2=12) = 60 Now, we add this 60 to 163 of 1636( i.e. we exclude the last digit), so we get 60+163=223 So, now the final answer becomes 2236 2: 52x46 Here, 5x4=20 & 6x2=12,so the preliminary number is 2012 Now, the rainbow product gives (5x6=30) + (4x2=8) = 38. Adding 38 to 201 gives 239. So,the final answer becomes 2392. Same is true for 95x99.
@varun2416 , 44 * 54 can be easily multiplied in 10 secs by using Rainbow Multiplication trick explained above (or you can even use Base50 as both no. are close to 50 )
You are right in saying that regular practice of Math is indispensable. But no matter how much you practice conventional methods they still would have limitations. It would still take lot of time to execute them (as you have to write down so many steps) That is why knowing these smart tricks is so important for a student .
Dear henchflex , You did everything right . It is just that you did not bother to Carry Forward at the end. The different answer parts you got were 63 ( 55 ) (12 ) , now simply add 5 of 55 and 1 of 12 to the left ( this is the std carry forward system of Math ) Answer is 68 62 Useful Tip: After putting the first part, there is only one place left for each part. Thus we simply forward ( add to the left ) the ten's digit of any 2 digit number we get. It is easy.
Dear hughaldrich , your ques 98x97 , Glad that you found out the answer yourself ( saved me the time to explain it again ) Useful tip : Since the numbers you have chosen to multiply are very close to a Base (100), thus you can also use Base method of multiplication ( watch the 3rd free video on glad2teach website )
To help you better understand my technique ( Rainbow Multiplication ) I am solving your question: 47 times 86 = ? Multiply first with the first and last with the last digit. We get 32__42 (pls note that 4 of 42 would be carried towards the left ) Now do the Rainbow ( multiply inside with inside, outside with outside and add them to get 80 ). 8 of 80 gets added to 32 to get 40 So we get 40 42 ( Answer ) Hope that helps you ( Shahryar, Glad2teach )
Tasos you can surely multiply 89 x 96 in 6 secs . Best part is you can choose any of the 2 EasyCal tricks [ Base Multiplication (BM) or Rainbow Multiplication (RM) ]. In this case I would prefer BM as both numbers are near Base100. Watch my video, Be Human Calculator on UA-cam 89 is at distance 11 from Base100 and 96 is at 4 . Subtracting the distance in a cross manner. 89-4 = 85 _ _ ( 2 more places to go ) 4 times 11 is 44 ( simply multiply the 2 distances) Final Ans = 85 44
Dear beabotelya, Rule of Carry Forward is when you have place for just one digit and you get a two digit number, you simply carry forward (to the left) the digit in ten's place. By carrying forward we add that digit to the next digit already present. It does not matter if the ten's digit is above 5 or not. It has nothing to do with that . Hope the explaination was of some help.
Dear rockvsaustinwm26, glad that I could help. Somebody has posted a comment below saying that I have just "Humanised" Mathematics. That's it. Though he said it sarcastically but it is by far the best compliment I have received as a Math teacher. Shahryar ( A.k.a Glad2teach )
Thank you so very much for your videos! I can't tell you how much they have helped me. Math was a nightmare to me. Now it's just plain fun. Thank you again! Take care, Bladen
Dear cwj415, glad that you figured out by yourself that this method does work for multiplying all 2 Digit x 2 Digit numbers . If you have any further query or confusion do let me know , i will be Glad2teach :)
Rayyan the EasyCal trick of instantly ( and mentally ) calculating Percentages and Discount is part of 30 EasyCal Videos of Fast Math Tricks. You can also use that trick to convert any fraction into a percentage. Like you can instantly find out what % you got if let's say you scored 142 marks out of total 160 marks in a test.
Dear d0tty11 , thanks for putting your comment. Though I don't agree that this method of multiplication will not work for Algebra. In fact this method works better and faster in Algebra as in Algebra there are no carry forwards ( thus one less step ) . Using the same technique ( Rainbow Multiplication trick ) you can multiply in a single step any Binomial x Binomial , Bino x Trino , Trino x Trino so on . See the Binomial multiplication video on Glad2teachalgebra channel to see what I mean .

@Doct8r, I humbly accept your gratitude and appreciation. Genius ...... I am as ordinary or as special as we all are. God has endowed all of us with this wonderful and powerful organ called brain. We just need to learn how to use it .
Dear SuperBlaze999 , glad that you are loving these 26 techniques of fast Algebra. The EasyCal trick you are trying to use is Rainbow Multiplication. In fact in the 26 Videos you have downloaded I have explained in detail how to apply this technique to multiply bigger numbers as well ( 3 digits or more ) . Do learn it from there. You have done everything right. Just carry forward (add to the left) the ten's digit (3) of middle term ( 37 ). You will get the answer. Read my comments below
sk20081 , it is difficult to explain the trick in text (watch the vid above). 47 * 86 = Multiply 1st digit with 1st digit and put the answer as it is ( no need to carry forward ) . So 4 x 8 = 32 ____ From here simply carry forward the ten's digit of every 2 digit no. we get Multiply last D with last D, 7 x 6 = 42 ( so 4 is carried forward to the middle ) Now do the Rainbow, 4x6 + 7x8 = 80 (as expected 8 is carried) So 32 + 8 = 40__ Final answer is 4042
32x21. 32x20=640. 32x1=32. 640+32=672. 44x52. 44x50=2200. 44x2=88. 2200+88=2288. I love watching videos like yours. The above is a method I came up with, although it is probably an already established method.
damn your good, i left school 24 years ago and have forgotten most tricks, my kids now ask me maths questions and it takes me a while to tell them and explain it to them your version is quicker than how i learnt it back in the 70's-80's maybe they can learn your way faster than my old rusty fashioned way
Dear SupaKaream, learning anything new is always a life changing experience, especially if someone has struggled with it for very long. Glad that my easycal videos series helped you learn Algebra. Regards Shahryar ( a.k.a glad2teach )
There is a very useful EasyCal Trick to calculate the percentages or discount easily ( and that too mentally ). It is done by simply Shifting the decimal towards the left and then adding. Trick is part of 30 EasyCal Video of Faster Math Tricks. But Qzak I am not able to fully understand what you are looking for as 31% of 1271 is 394.01 not 41 .
Jenica You keep the 4 from 64 in the line so it's 14_4 and you have to add the remaining 6 to the number you get from rainbow mulitiplication, which us 72, you add 7 to 14 = 21 add remaining 6 to 2 (from 72) = 8 and add number 4 that you had = 2184
There are no rules. This trick will work for multiplying all two digit numbers directly. Just take care of carry forwards. You can watch the complete video of this trick ( with more examples ) by downloading the free trial copy from glad2teach website

To see this technique in action watch my Live Seminar video I have uploaded. Click on my name (glad2teach), the name of that video is " Teaching to be Super-Sonic at Math"
To henchflex: the last digits you say is 12. so it will be 63_12 but becos the last digits has two digits, so u carry foward the 1. then u will end up with 6862 (the third digit is the additional of 1[the second digit of the last digits] and 5[the last digit of the middle digits])
. missiondoe , In Full Easycal-Algebra Series (26 Videos of Faster Algebra Tricks) you learn to multiply even huge 5 digit numbers directly (not just 2 or 3 digit numbers). All the tricks have been explained with many examples so that you can master them with ease. .
Dear abhinayan27, glad that you could benefit from my Math Videos. I cannot even say which is my favourite colour, let alone the numbers ( which are infinite !! ). Numbers are indeed beautiful.
Hello missiondoe , The trick to multiply directly with a 3 digit number has been already explained by me in 26 EasyCal Videos of Faster Algebra. Your try is admirable. But you don't have to reinvent the wheel. Just watch the video and you are done. All the Best !!
it looks similar, but its not the same. foil is used for multiplying binomials, and the answers can b written in any order. this is used for multiplying integers and the answers display exactly where they will appear in the final number, and are not interchangeable.
6x4=24;6x9=36 so answer is in form 24_36 finding missing numbers '_': [6x9=54 (outer)] + [4x4=16 (inner)] = 70 since last digit is '0', we don't put it in the missing '_' space, but add the 7 to number in front of '_' like this: 2436 + 0700 ------ 3136

Sir i am saurabh gawande from maharashtra at washim in taluka karanja lad.I am little bit good in But sir when i saw your videos that i am practising today! Thanks Sir! I am always thankful to you! And iam, 13 years old boy so thank you!
Dear GTAvideofue , glad to know that I have an ardent fan like you. Wish you all the success in life. PS: Do record your Convocation Speech and upload it to youtube.
(2x2=4) So the first digit is 4. [(2x5=10)+(4x2=8)]=18 so you have to add the one to the 4 because you only have one space so your first two digits are 58. Then you multiply (4x5=20) so you carry the two leaving you with 600.
Dear Aaaron, your issue is different. You are trying to install the exe file of EasyCal Videos on a Mac. You need a PC to do so. If you have a PC then pls install EasyCal File on it and the Video would start to play immediately. You can then email us your Product Key If not, then I would get your order cancelled and fully refunded in 24 hours. Shahryar (Glad2teach)
@BobByler Hey Bob, I just checked out your site and videos. And I have to say I'm not satisfied at all, it's like reading from a Math book sorry. As a child I always hated math, but Mr Shahryar, your videos really helped me. Gotta say its like a life changing experience, never thought I could learn Algebra so easily. Really appreciate it, much love.
This is simply FOIL (First-Outer-Inner-Last) multiplication. e.g. 44 * 52 = (40 + 4)*(50 + 2) = (40 * 50) + (40 * 2) + (4 * 50) + (4 * 2) This trick is the same thing but in a more compact form.
Dear lightjello , your ques 72 x 62 = ? You should be able to do this calculation easily using the EasyCal trick of Rainbow Multiplication explained above (in the vid) or below (in the comments). Atleast try it ....
Wow, i really enjoy your videos i just found out yesterday and its a really good use, specially if you are a teacher. I am going to try this out with my students, sounds faster and easier :) thanks!
I tried it -9x9 (first digits) = 81, so thats 81_ _ -9x9 (last digits) = 81, so thats 81 _ 1 -Do the rainbow mutiplication, and you'll get 162 -Now when you did step 2, you got 81 as a result, so lets say the result would be 8181. When you do the rainbow multiplication, you get 162 as a result. Add 8+2 and you get 10, then you transfer 10 to the next number, and stay only with a 0, so it means you will have 1+1+6=8. Then, do 8+1=9. You get 9801. Basicly its this: 8181 +162 ------- 9801
@ntt4rz its working too, you have to add, from left to right, the 421, from the fist operations steps, with the second results. 421+ 14 _+-- 2x7 _6_= --2x3 621
I soooo need the full video set but you do not have it for mac operating system. you make it so simple to solve these problems and I really need help with quadratic equations. Could you recommend another way to get your videos.
All your examples make a perfect sense. However, I'm stuck in this one : 78 times 28. I get the first digits by multiplying 7*2 = 14 and last digits 8*8=64. Thus, I get 14_64. Doing rainbow multiplication to fill the blank space, I multiply 7*8 = 56 and 8*2=16. Adding 56+16=72. Now, I'm adding 7 with 17 to get 24 and letting 2 sit in the blank space. As a result the figure I derive is 24264 which is mathematically wrong. Could you throw some light on this? Thanking you in advance.
Great technique, can you do the opposite easily? 31 % 1271 = 41 41 % 1271 = 31 Please let me know if there's an easy way to do this, now that I have mastered multiplication :)
Hi Shahryar, thanks for the quick reply. I don't have a PC but I have been trying to use CrossOver to play the video. Is it possible to 'unlock' the video and then play it with VLC on a Mac. Honestly these videos are really helpful I just want to be able to play them on my Mac.
That's a tough one given the 'carry-overs'. But using this model, 9*3 = 18, (6*2)+(3*9)=39, 3*6=18. Then 18 with 39 goes 18+3 followed by 9. 219 followed by 18, so 2208. The 1 of the last '18' gets carried over to the 9, which turns to 10, which has its 1 carry over to the 21, making it 22. 2208
it wokrs, you idiots xD 9x2 is 18 _ then 6*3 is 18, so you leave 8 at last number, then you have 1 in mind on blank space. Then thge number of multi[plying and adding is 12+27+1*(this one was in mind)= 40 so you add 4 to 18 it gives you 22then you have 08... 2208
i would like to watch the rest of the videos, so i went to the link, it has a cost, i dont mind, but the link is about algebra, and i am not interested on algebra, only in aritmetic, can anyone help me on this.
Am I doing this wrong, or doesn't it work with 45*78? 4*7 = 28 (28_) 5*8 = 40 (28_40) 4*8 + 5*7 20 + 35 = 55(28(55)40 5 28540 33540 What did I do wrong? Or what do I have undone?
How would I know which method to use for certain problems...this method or the method used in Be Human Calculator? Ex. 22x32. I get the wrong answer with this method but right with your other method that I mentioned...
you can use the other method for that 2 3 98*97 97-2 or 98-3 =95 the first digits 2*3= the last digits answer=9506 credits goes to glad2teach for learning me this
I watched the video, then i did a Multiplication test and my teacher was shocked and thought that i was cheating on it but i wasn't, and my teacher thinks i'm a genius but i owe it all to glad2teach thanks very much!
Actually, it does.
1: 86x26
8x2=16 & 6x6=36 ,so for now, the number is 1636.
Now after we do the rainbow multiplication, we get (8x6=48) + (6x2=12) = 60
Now, we add this 60 to 163 of 1636( i.e. we exclude the last digit), so we get 60+163=223
So, now the final answer becomes 2236
2: 52x46
Here, 5x4=20 & 6x2=12,so the preliminary number is 2012
Now, the rainbow product gives (5x6=30) + (4x2=8) = 38.
Adding 38 to 201 gives 239.
So,the final answer becomes 2392.
Same is true for 95x99.
thank you very much
@varun2416 , 44 * 54 can be easily multiplied in 10 secs by using Rainbow Multiplication trick explained above (or you can even use Base50 as both no. are close to 50 )
You are right in saying that regular practice of Math is indispensable. But no matter how much you practice conventional methods they still would have limitations. It would still take lot of time to execute them (as you have to write down so many steps) That is why knowing these smart tricks is so important for a student .
Dear henchflex , You did everything right . It is just that you did not bother to Carry Forward at the end.
The different answer parts you got were
63 ( 55 ) (12 ) , now simply add 5 of 55 and 1 of 12 to the left ( this is the std carry forward system of Math )
Answer is 68 62
Useful Tip:
After putting the first part, there is only one place left for each part. Thus we simply forward ( add to the left ) the ten's digit of any 2 digit number we get. It is easy.
You are most welcome ..The whole endeaver of Glad2teach is to make Mathematics really easy for everyone .
Dear hughaldrich , your ques 98x97 ,
Glad that you found out the answer yourself ( saved me the time to explain it again )
Useful tip : Since the numbers you have chosen to multiply are very close to a Base (100), thus you can also use Base method of multiplication ( watch the 3rd free video on glad2teach website )
To help you better understand my technique ( Rainbow Multiplication )
I am solving your question: 47 times 86 = ?
Multiply first with the first and last with the last digit.
We get 32__42 (pls note that 4 of 42 would be carried towards the left )
Now do the Rainbow ( multiply inside with inside, outside with outside and add them to get 80 ).
8 of 80 gets added to 32 to get 40
So we get 40 42 ( Answer )
Hope that helps you ( Shahryar, Glad2teach )
Tasos you can surely multiply 89 x 96 in 6 secs . Best part is you can choose any of the 2 EasyCal tricks [ Base Multiplication (BM) or Rainbow Multiplication (RM) ]. In this case I would prefer BM as both numbers are near Base100. Watch my video, Be Human Calculator on UA-cam
89 is at distance 11 from Base100 and 96 is at 4 . Subtracting the distance in a cross manner.
89-4 = 85 _ _ ( 2 more places to go )
4 times 11 is 44 ( simply multiply the 2 distances)
Final Ans = 85 44
Thank you for posting these helpful videos! I wish they would have taught us this method in school.
Dear beabotelya, Rule of Carry Forward is when you have place for just one digit and you get a two digit number, you simply carry forward (to the left) the digit in ten's place. By carrying forward we add that digit to the next digit already present.
It does not matter if the ten's digit is above 5 or not. It has nothing to do with that . Hope the explaination was of some help.

sk20081 , it is difficult to explain the trick in text (watch the vid above).
47 * 86 = Multiply 1st digit with 1st digit and put the answer as it is ( no need to carry forward ) . So 4 x 8 = 32 ____
From here simply carry forward the ten's digit of every 2 digit no. we get
Multiply last D with last D, 7 x 6 = 42 ( so 4 is carried forward to the middle )
Now do the Rainbow, 4x6 + 7x8 = 80 (as expected 8 is carried) So 32 + 8 = 40__
Final answer is 4042
32x21. 32x20=640. 32x1=32. 640+32=672.
44x52. 44x50=2200. 44x2=88. 2200+88=2288.

You keep the 4 from 64 in the line so it's 14_4 and you have to add the remaining 6 to the number you get from rainbow mulitiplication, which us 72, you add 7 to 14 = 21 add remaining 6 to 2 (from 72) = 8 and add number 4 that you had = 2184
There are no rules. This trick will work for multiplying all two digit numbers directly. Just take care of carry forwards.

the last digits you say is 12.
so it will be 63_12
but becos the last digits has two digits, so u carry foward the 1.
then u will end up with
6862 (the third digit is the additional of 1[the second digit of the last digits] and 5[the last digit of the middle digits])

6x4=24;6x9=36
so answer is in form 24_36
finding missing numbers '_':
[6x9=54 (outer)] + [4x4=16 (inner)] = 70
since last digit is '0', we don't put it in the missing '_' space, but add the 7 to number in front of '_' like this:
2436 +

Sir i am saurabh gawande from maharashtra at washim in taluka karanja lad.I am little bit good in But sir when i saw your videos that i am practising today! Thanks Sir! I am always thankful to you! And iam, 13 years old boy so thank you!
Dear GTAvideofue , glad to know that I have an ardent fan like you. Wish you all the success in life.
PS: Do record your Convocation Speech and upload it to youtube.
Wow, thanks for the tip! This is so helpful!
(2x2=4) So the first digit is 4. [(2x5=10)+(4x2=8)]=18 so you have to add the one to the 4 because you only have one space so your first two digits are 58. Then you multiply (4x5=20) so you carry the two leaving you with 600.
Yes, great videos. These are great for homeschoolers too.
Dear Aaaron, your issue is different. You are trying to install the exe file of EasyCal Videos on a Mac. You need a PC to do so. If you have a PC then pls install EasyCal File on it and the Video would start to play immediately. You can then email us your Product Key If not, then I would get your order cancelled and fully refunded in 24 hours. Shahryar (Glad2teach)
this site should be more popular
@BobByler Hey Bob, I just checked out your site and videos. And I have to say I'm not satisfied at all, it's like reading from a Math book sorry.
As a child I always hated math, but Mr Shahryar, your videos really helped me. Gotta say its like a life changing experience, never thought I could learn Algebra so easily. Really appreciate it, much love.
This is simply FOIL (First-Outer-Inner-Last) multiplication.
e.g. 44 * 52 = (40 + 4)*(50 + 2)
= (40 * 50) + (40 * 2) + (4 * 50) + (4 * 2)
This trick is the same thing but in a more compact form.
awesome job! I go to primary school and I see this very helpful thanks :)
Dear lightjello , your ques 72 x 62 = ?
You should be able to do this calculation easily using the EasyCal trick of Rainbow Multiplication explained above (in the vid) or below (in the comments). Atleast try it ....
Very good, easy-to-understand video
Thanks very much
the best maths trick so far ...........
Wow, i really enjoy your videos i just found out yesterday and its a really good use, specially if you are a teacher. I am going to try this out with my students, sounds faster and easier :) thanks!
if i had a chance i would just go on youtube and learn bc i learn so much more if i see it on youtube
I found out what I did wrong thx slot for these videos you a a life saver :)
Thank you sir, wish you many blessings
I tried it
-9x9 (first digits) = 81, so thats 81_ _
-9x9 (last digits) = 81, so thats 81 _ 1
-Do the rainbow mutiplication, and you'll get 162
-Now when you did step 2, you got 81 as a result, so lets say the result would be 8181. When you do the rainbow multiplication, you get 162 as a result. Add 8+2 and you get 10, then you transfer 10 to the next number, and stay only with a 0, so it means you will have 1+1+6=8. Then, do 8+1=9. You get 9801. Basicly its this:
8181
+162
-------
9801
this is a great way to learn multiplication!!!!!!!!!!!!!!!
dude i'd luv if u make an hour long video of all that u know,i mean tricks..thanks i'm glad2learn frm u glad2teach :)
@ntt4rz
its working too, you have to add, from left to right, the 421, from the fist operations steps, with the second results.
421+
14 _+-- 2x7
_6_= --2x3
621
I soooo need the full video set but you do not have it for mac operating system. you make it so simple to solve these problems and I really need help with quadratic equations. Could you recommend another way to get your videos.
u r a great teacher sir
do you carry over every time you get a # more than 10? and how do you know how many spaces to leave?
Thanks a lot sir.I am a ibps po aspirant and this is surely going to go a long way in helping me.
All your examples make a perfect sense. However, I'm stuck in this one : 78 times 28. I get the first digits by multiplying 7*2 = 14 and last digits 8*8=64. Thus, I get 14_64. Doing rainbow multiplication to fill the blank space, I multiply 7*8 = 56 and 8*2=16. Adding 56+16=72.
Now, I'm adding 7 with 17 to get 24 and letting 2 sit in the blank space. As a result the figure I derive is 24264 which is mathematically wrong.
Could you throw some light on this? Thanking you in advance.
@glad2teach colours are infinite too!
Great technique, can you do the opposite easily?
31 % 1271 = 41
41 % 1271 = 31
Please let me know if there's an easy way to do this, now that I have mastered multiplication :)
Hi Shahryar, thanks for the quick reply. I don't have a PC but I have been trying to use CrossOver to play the video. Is it possible to 'unlock' the video and then play it with VLC on a Mac. Honestly these videos are really helpful I just want to be able to play them on my Mac.
Great tutorial, keep up the great work!
OMFG keep these videos coming!!
@glad2teach im going to tell mrs.davis (my math teacher) thanks!
how to purchase this .... vedic maths books .
All use this simple method. And to multiply 68*40 is more harder than just to multiply 1-9 with 1-9!
It does work...
29*77=14_63
then by rainbow 63+14=77
14+7_(7+6)3=21_(12)3
Carry forward 1 from 12 and add it to 21=2223
Hi does this method works in 3 digits X 3 digits ??
Sir all of your videos are so awesome . Thank you so much ... they all are really helpful
It does work for 86 x 26, 52 x 46, and 95 x 99.
Yes, I am
Thank-you, I'll come again.
How to multiply 96*23 = ?? ....I'm not getting it through that method ...can u explain it please
That's a tough one given the 'carry-overs'. But using this model, 9*3 = 18, (6*2)+(3*9)=39, 3*6=18. Then 18 with 39 goes 18+3 followed by 9. 219 followed by 18, so 2208. The 1 of the last '18' gets carried over to the 9, which turns to 10, which has its 1 carry over to the 21, making it 22. 2208
A Britto 9*3 = 18. LOL.
Brad Eyman
What's wrong with it? It's Obamamath!
it won't work with this method
it wokrs, you idiots xD 9x2 is 18 _ then 6*3 is 18, so you leave 8 at last number, then you have 1 in mind on blank space. Then thge number of multi[plying and adding is 12+27+1*(this one was in mind)= 40 so you add 4 to 18 it gives you 22then you have 08... 2208
It is never too late .. Isn't it
This way really super , really thank you its making me really faster on hard calcu. math problems
i would like to watch the rest of the videos, so i went to the link, it has a cost, i dont mind, but the link is about algebra, and i am not interested on algebra, only in aritmetic, can anyone help me on this.
Am I doing this wrong, or doesn't it work with 45*78?
4*7 = 28 (28_)
5*8 = 40 (28_40)
4*8 + 5*7
20 + 35 = 55(28(55)40
5
28540
33540
What did I do wrong? Or what do I have undone?
ccan you do 28x18 ? i keep getting the wrong answer where did i go wrong ?
What app are you using? Please answer
Very very easy method use for every learning child
Ok I get it now.
Thanks for the tutorial.
How would I know which method to use for certain problems...this method or the method used in Be Human Calculator? Ex. 22x32. I get the wrong answer with this method but right with your other method that I mentioned...
Jessica Tinajero 22*32=6_4, now 4+6=10, put this 0 in the gap, 1left, left for left. so it is added with 6, its 6+1=7. so 704
you can use the other method for that
2 3
98*97
97-2 or 98-3 =95 the first digits
2*3= the last digits
answer=9506
credits goes to glad2teach for learning me this
if there is a zero in the middle do we take that out of the answer?
wow.. amazing trick.. thanks for sharing genious.
