As stated before, multiplication is just a quick way to do addition problems. To add 10 + 10 +

10 + 10 + 10 = 50 is the same as multiplying 10 x 5 = 50. However, to be able to solve more difficult

problems quickly and accurately, you must understand and know the multiplication table below.

The same table can be found on page 65 for easy reference.

Here's how to use the table: Any number in the left-hand column multiplied by any number in

the top line equals the number under the one in the top line and opposite the one in the left-hand

column. Let's multiply 7 (left-hand column) by 8 (top line): 7 x 8 = 56. What is 9 x 9?
