### Multiply By 11…

Welcome back!!!

In the previous blog we had seen **Find the answer without knowing the question**.

Let’s begin.

Consider the problem:

35 X 11

To solve this problem, simply add the digits, 3 + 5 = 8, put the 8 between the 3 and the 5, and there is your answer:

385

Suppose the problem is

84 X 11

Although 8+4=12, here the sum of two digits is in double digits, so the answer is NOT 8124!

As before, the 2 goes in between the numbers, but the 1 needs to be added to the 8 to get the correct answer:

924

With even more practice, you will be able to perform many calculations faster than someone using a calculator.
