Multiplying whole numbers starts with a solid knowledge of a multiplication table

I may never say this enough! The more you know your multiplication table, the easier it is going to be for you to perform multiplication.

When numbers are multiplied, each number is called a factor. The result of multiplying numbers is called a product

Look at the following multiplication problems.You can get your answer right off a multiplication table.Note that 0 × 6 = 0. In fact, any number times 0 = 0.

The following is a multiplication of two-digit by a one digit (46 × 7)

Study this example carefully!

Notice that when the product of the ones is greater than 9, you must rename the tens and ones. In our example above, 42 ones were renamed 4 tens and 2 ones. Then, the 4 tens are added to the 28 tens in the tens column to get 32 tens. It can be time-consuming to write the tens and the ones when doing multiplication. You can also do the following: |

For example, multiply 46 by 37. Look at the way it is done below and notice that you already performed the multiplication for 46 × 7 and 46 × 3
