Multiplying numbers by 10
Multiplying a unit number by 10 moves it into the tens column. Multiplying a tens number by 10 moves it into the hundreds column. You can think of it like taking the zero from the 10, and putting it at the end of the number you are multiplying, so 2 x 10 = 20, and 20 x 10 = 200
Can you think what 33 x 10 will be? Put the zero from the ten at the end of the 33, and it gives you the answer, 330.
