The first part of this trick requires two numbers. So, pick any two. The trick works a bit better when at least one number is 10 or more. So, for this instructable, I will choose 15 x 19.

There are the 3 steps:

a) Multiply vertically on the left: 2 x 2 = 4.

This gives the first figure of the answer.

b) Multiply diagonally and add: 2 x 3 + 1 x 2 = 8

This gives the middle figure.

c) Multiply vertically on the right: 1 x 3 = 3

This gives the last figure of the answer.

Final answer = 483

Works for any two 2 digit numbers. Sometime you have to carry numbers but its still easy. You know how you read about people who can multiply huge numbers? This is how they do it.
