The set of lines and numbers above is the Multiplication Table. It was on the back of a

bound tablet that I got in the first grade. It was brown. It would be to your advantage

to copy this table to a sheet of lined paper. Use a ruler to make the verticle lines.

Did you not have something like this when you were in the third grade?

When you add two numbers together, the name for the result is called the sum.

When you multiply two numbers together the name for the result is called the product.

Say you have two dozen eggs and you want to know how many eggs you have. Since you know that

there are 12 in a dozen you find 12 in the top row and you put your right index finger on

the 12. You then find 2 in the first column and you put your left index finger on the 2.

First with your left finger you move it to the right, keeping your finger in the same row

and then you bring your right finger down, keeping it in the same column until your fingers

meet at the box that has 24 in it. Thus you determine that the product of 2 and 12 is 24.
