Trick for multiplication of 11 with any number

In today's post i will tell you the trick to Multiply any 2 digit number with 11 and get answer in just a second.

Trick is simple and easy to remember take any 2 digit number, lets take 23 for example
23 * 11 = ?
->the first digit of our answer will be the first number itself in our case its 2 as we are multiplying with 23 so the answer will be =>2---
->the last digit of the answer will be the last number itself in our case 3 (same reason as above) =>--3
->sum of first and last digit will give us our middle digit 2+3 (5) =>-5-
23 * 11 = 25

lets try for 57 * 11
-> first number = 5--
->last number = --7
->middle numbers 5+7 = 12, carry 1 to its previous number which is 5 so (5+1=6),now our first number is 6
the answer for 57 * 11 = 627

similarly  68 * 11 = 6 (14) 8 (carry 1 to its previous number)
answer will be => 748

Note :- This trick will only work for the multiplication of 11 only
try for some other combination like 47 * 11, 30 * 11 for your better practice
