# Multiplying by 10

This chapter explores how to multiply by 10. This is a very simple chapter and you’ll find that multiplying by 10 is very simple.
Suppose we wanted to multiply 2 by 10. First we would arrange the numbers like the following.
First we multiply 2 by zero and get;
…and then multiply 2 by 1 as shown below.
Above we see that when you multiply 10 by 2 the answer is 10.
Suppose we wanted to multiply 66 by 10. First we would arrange the numbers like the following.
First we multiply 0 by 6 to get 0.
Then multiply 6 by the other zero as shown below;
In the next column we place an extra zero as shown below.
Then we multiply 1 by 6 as shown below.
Then we multiply 1 by the other 6 and get 6 as shown below.
As we see above when you multiply 66 by 10 you get 660.
