# Speed Multiplication by 111 : Vedic Maths

Multiplication of a number consisting of only ones with another number becomes very easy using **Vedic Maths** techniques. You must see the earlier post on shortcut for multiplying a number by 11

**MULTIPLYING A NUMBER BY 111**

To multiply a two-digit number by 111, add the two digits and if the sum is a single digit, write this digit TWO TIMES in between the original digits of the number. Some examples:

36×111= 3996

54×111= 5994

The same idea works if the sum of the two digits is not a single digit, but you should write down the last digit of the sum twice, but remember to carry if needed. So

57×111= 6327

because 5+7=12, but then you have to carry the one twice.

For 3 digit numbers

Carry if any of these sums is more than one digit.

Thus 123×111 = 1 | 3 (=1+2) | 6 (=1+2+3) | 5 (=2+3) | 3

Similarly,

241×111 = 26751

For an example where carrying is needed

Say, 352×111=3 | 8 (=3+5) | 10 (=3+5+2)| 7 (=5+2)| 2

= 3 | 8 | 10 | 7 | 2 = 3 | 9 | 0 | 7 | 2

= 39072

(Because of the carries, it may be easier to do the sums and write the answer down from right to left.)

Let me know, if you liked this **Vedic Maths** trick.

3 of them are awesome..nice i lyk it

really it is good

really it is to good.

i likd these tricks,its veryuseful for cmptitiv xams and also fr smrt wrk

tricks given are awesome……………..thanks for that

if u have more tricks share with me na……….sravani.rayala366@gmail.com

i m grateful to u sravani.rayala366@gmail.com

great job………………………. enjoyed knowing tricks thanks a lot

its good keka

hi Gud Mrg Frnds……….. i like this type of tricks…….

I think first multiplyling by 999 and then dividing with 9 will take less time.

Ex. 123*111= 123*999/9= 122877/9=13653. And in this process we can multiply with 1111 or 11111 or 222 or 4444 or the like.

And the process to multiply with 999 or the like,

Process 1:

If number of 9 is equal to or greater than the number of digits to be multiplied:

3154*9999=

first we have to substract 1 from the very number & write down it from the left. Here, 3154-1=3153.

Now we substract it from 9999. Here, 9999-3153=6846. & write it to the write of 3153. It is the answer required. 3154*9999= 31536846.

3154*99999=315396846.

Process 2:

If the number of nine is less than the digit of the number:

456*99=

first we leave the number equal to number of 9 from right side. Here no of 9 is 2, so we leave 56. Now we add 1 with the remaining number and substract it from original one. Here, 4+1=5, 456-5=451. Now we write it to the left side. Next, we substract the digit we kept aside (here 56) from the number more than 1 of the multiplicator ( i.e, (99+1)-56=44) and write it to the right. Therefore, 456*99=45144.

Ex 2. 526*9

6 kept aside. (52+1)=53, (526-53)=473, now ((9+1)-6)=4,

therefore, 526*9=4734

yah its nice yaaa

Its a very nice method but what to do when to multiply by 2222 or 444 as mentioned

I think first multiplyling by 999 and then dividing with 9 will take less time.

Ex. 123*111= 123*999/9= 122877/9=13653. And in this process we can multiply with 1111 or 11111 or more.

i really liked the trick.it was worth learning nd above all “vedic mathematics” is what the world dies for.
