Now there are a few videos that I would like you to watch that explain a few different methods that you can use in multi-digit multiplication.
The Standard Method:

This method follows four easy steps to two digit multiplication:
Step 1: multiply the entire top number by the ones digit (including carrying)
Step 2: add a zero to hold your place value
Step 3: multiply the entire top number by the tens digit (including carrying)
