Multiplication of 11 with any number of 3 digits.

Maths Tricks , short cut tricks for maths to make calculation easy and fast

Multiplication of 11 with any number of 3 digits. Let me explain this rule by taking examples 1. 352*11 = 3---(3+5)---(5+2)---2 = 3872 Means insert the sum of first and second digits, then sum of second and third digits between the two terminal digits of the number 2. 213*11 = 2---(2+1)---(1+3)---3 = 2343: Example.
Here an extra case arises
Consider the following examples for that

1) 329*11 = 3--- (3+2) +1--- (2+9-10) ---9 = 3619
Means, if sum of two digits of the number is greater than 10, then add 1 to previous digit and subtract 10 to the associated digit.
2) 758*11 = 7+1---(7+5-10)+1---(5+8-10)---8 = 8338; Is this maths trick helpful? (10361) (3029) Post / Read comment (40)

Easier method is to write the number and write it again, but move it to the tenth.
Like this:
353*11 = 353

let us take 758*11 as a example: here write the unit digit as it is,then from the unit digit add unit digit and tenth place value,then write hundred^th value as it is.
if we get no like 15 or something write the unit place value and move the tenth place

yes...it works all digits of 111,1111,11111 and so on...
adding digits upto digits of second number
329*111=3---(3+2)---(3+2+9) ----(2+9)---9=36519
Means, if sum of two digits of the number is greater than 10, then add 1 to previous digit and subtract 10

Ravi Garg (8 years ago)

I am taking same example--
329*11
3--(3+2)--(2+9)--9
in this case on adding 2 and 9 we get 11 i.e, greater than 10 so we can simply break the number from 11 to 1 and 1. This means add 1 to previous number and take 1 for associate number
3--5+1---1--9=3619

shilpa patel (7 years ago)

Easy trick for a MULTIPLICATION OF 11 WITH ANY NUMBER OF any DIGITS is
Number*10=Ans+Number
Example. Number=8956 multiply with 11
so, first 8956*10=89560 then add 8956 and final ans is 98516

any value multiplied by 11 can be done in this way too. add zero at the last of the given number and add the result to the given number.
