Multiplication is the process of adding equal sets together. 22+2+= 6 We added 2 three times.

3
Instead of repeatedly adding, we can multiply. x 2 3 6

4
This means “3 groups of 2 equals 6 in all”. x 2 3 6

5
This means “2 groups of 3 equals 6 in all”. x 3 2 6

6
This means “3 groups of 4 equals 12 in all”. x 4 3 12

7
This means “4 groups of 3 equals 12 in all”. x 3 4 12

8
x 6 This means “2 groups of 6 equals 12 in all”. 2 12

9
We can also use multiplication to find the total number in this set without having to count them.

10
3 x 6 = 18 3 6

11
Or we can turn it the other way and show it like this.

12
6 x 3 = 18 3 6

Distributive Property This example says we have 8 groups of 2d+9. Instead of writing 2d+9 eight times then adding there is a shorter was using multiplication.
