Inspect this multiplication problem:


      4

This is a multiplication problem presented in a vertical format. It is the same as each of these multiplication problems:


  4 x 2 = 		2 x 4 = 		  2
						x 4

In each case you get the same answer: 8.

Here are a few more examples for you to study:


	  3			   4			   5
	x 3			 x 2			 x 1
       -----			-----			-----
	  9			   8			   5

Now you will try a few of these yourself.
