Step 1: Setup
Set up your multiplication problem like this:

	1	1
x	1	1

Step 2: Multiply
1 x 1 = 1. Put 1 below the line and 0 as a reminder on top:

	0
	1	1
x	1	1
		1

Step 3: Multiply
1 x 1 = 1. Take 1 and add 0 from the previous step to get 1. Enter 1 at the bottom:

	1	1
x	1	1
	1	1

Step 4: Add 0
Enter a 0 at the bottom right as a place holder, because you now move over one digit:
