Aside from the standard multiplication algorithm (algorithm really means steps or methods) that we already know, there is another method to do multiplication. That is, to place the numbers in squares. This method can be used for multiplying 2-digit numbers. We will call this method the *Square Diagonal Multiplication Algorithm*

**Steps in Multiplication Algorithm**

1. Create a 2 by 2 square and place the numbers on top and on the right side. Each digit should be assigned to one row and one column. The example is shown below for 63 × 17.

2. In each square, draw a diagonal slanting to the right. Continue reading
