## Math Magician Trick to check multiplication of any two given numbers is done correctly

We are going to introduce amazing trick to check multiplication of any two given numbers is done correctly.  Let us check how its steps goes.

First Step  : Check the sum of the digits of the numbers we are going  to be multiplied .

Second Step :Multiply the results obtained in step 1 and find its sum of digits you got.

Third Step :Get the sum of the digits of the real answer you got .

Forth Step :Compare the digits in step two and three If its same then it means you have multiplied correctly.

Examples

Let us consider an example to understand better Example 1: 403*255=102765

We need to check whether 102765 is the correct answer. So lets follow the steps

First Step :Check the sum of the digits of the numbers we are going  to be multiplied.Digits of 403 403=4+0+3=7 Digits of 255 255=2+5+5=3

Second  Step:Multiply the results obtained in step 1 and find its sum of digits you got. we get, 7x 3=21 finding sum of digits of 21 21=2+1=3

Third Step:Get the sum of the digits of the real answer you got .102765 102765=1+0+2+7+6+5=21=2+1=3

Forth Step:Compare the digits in step two and three If its same then it means you have multiplied correctly.In this case both times answer is 3. So We can say 403*255=102765 is exactly right.

This is a good way to impress your friend. Its a good magic and math magician multiplication trick.
