Summarize the following:
Any number times 1 is equal to itself. Any number times zero equals zero. Multiply the bottom right number by the top right number. Multiply the bottom right number by the top left number. Multiply the bottom right number by the top right and then the top left numbers. Shift the second row one digit to the left. Multiply the bottom left number by the top right and then the top left numbers. Add the columns together. You want to multiply 34 x 6. You start by multiplying the 1s column (4 x 6), but you can't have 24 1s in the 1s column. Keep 4 1s in the 1s column. Move the 2 10s over to the 10s column. Multiply 6 x 3, which equals 18. Add the 2 that you carried over, which will equal 20.

Summary:
Start with 1s and 0s. Memorize the multiplication table. Practice single-digit multiplication problems Multiply 2-digit numbers times 1-digit numbers. Multiply 2 2-digit numbers. Multiply and regroup the columns.
