Factors

Using division and the associative property

Associative Property Review



Changing the grouping of the factors does not
change the product.

(3 x 2) x 3 = 18

3 x (2 x 3) = 18

Think: "grouping." Associative Property


When Multiplying:

** First multiplying the parenthesis ( )

** Then multiply the last number to get your product.


(5 x 7) x 2
35 x 2 = 70
is the same as...
5 x (7 x 2)
5 x 14 = 70




Another Way To Look At It...

When Multiplying:


(2 x 5) x 3 = 2 x (5 x 3)
10 x 3 = 2 x 15
30 = 30


or


(2 x 3) x 4 = 2 x (3 x 4)

6 x 4 = 2 x 12

24 = 24
