There is a easy way to get the multiplication with 11.

suppose if any one ask you 53*11

then what you will do?

You will multiply that is

53
53*
____
583
_____ This is the final result.

but this may take some time to calculate.

So we can use a trick to calculate this with in a second.

53*11= 5+3=8 so place this 8 between 5 and 3 that is 583 there for the answer is 583

This is known as MATHMAGIC

If the calculation with 3 digit number

then 583*11= 5+3=8

Now place this 8 in between 5 and 3

that is 5883

5(58 8+3)3
5(5(8+1)1)3
5(591)3
5(5+9)13
5(14)13
(5+1)413
6413

very simple. Just try it.

I hope you understood.

There is another magic with eleven. The total of digits first, third, five and so on will equal that from second, fourth, sixth digit etc, when the figure is divisible by eleven. So, if you want to know whether a number is divisible by eleven, just total as above.

Thus 121 the first and third digit equal the second. In 132, also the same. In 1320, 0+3 = 2+1. Hence, divisible by eleven. You may check even very large number.
