What is Multiplication?



Multiplication is all about GROUPS of things arranged in ways you can count them more quickly than just adding, adding and adding. You can think of the multiplication sign as just a lot of addition signs together. For example 3 + 3 + 3 is the same as 3 GROUPS OF 3 or 3 x 3.

6 + 6 + 6 + 6
is the same as
4 GROUPS OF 6
and the same as
4 x 6
and the same as
   6
x 4 (you read from bottom to top: 4 groups of 6).

7 + 7 + 7 + 7 + 7
is the same as


7 GROUPS OF 5
and the same as
5 x 7
and the same as
   7
x 5 (bottom to top: 5 groups of 7)
