Multiplication

There is not just one way to multiply.  The traditional way is to line up the one's, ten's and so on, then multiply up and across from the bottom right number then the same thing for the bottom left number and add the answer. Like shown below:

 12

x 2

 24

Other ways are lattice and the partial methods.

Lattice method uses a box.

This example is multiplying 134x39 and the answer is across the bottom, 5226.

The Partial method multiplies the bottom number by the top numbers but using its place value. As shown below: 

Whatever way you choose to multiply is fairly simple, with some practice.
