1 Associative Property By Monica Yuskaitis

2 The Associative Property is like a man and woman getting married. First, they are each counted separately, then after they are married they are counted as one, even though they are still separate people.

3 Before a couple are married they are considered as two separate people.

4 After the marriage they are considered as one.

5 These numbers are all separate = 6 x 3 x 8 x 4 =

6 The numbers with parentheses around them are counted as one number. (4 + 5) = 6 x 3 x (8 x 4) =

7 Therefore, the operations inside the parentheses must be done first. (4 + 5) = 6 x 3 x (8 x 4) =

8 The numbers are associated together.

9 Definition Associative Property – the addition or multiplication of a set of numbers is the same no matter how the numbers are grouped. (4 + 3) + 9 = (3 + 9) = 16

10 Definition Parentheses – the enclosing symbols ( ) which indicate that the terms within are considered as one unit. (4 + 3) + 9 = 16

11 Definition Parentheses – ( ) are also called grouping symbols (4 + 3) + 9 = 16

12 Order of Operations The operations within parentheses must be done first before the other operations. (4 + 3) + 9 = = 16

13 Solve these problems (76 – 13) + 20 = 60 – ( ) = ( ) – 125 = 75 – (25 -13) = 88 + (55 – 13) =

14 Check Did you remember to do the operations in the parentheses () first?

15 Solve these problems Let n = 5 (16 – n) + 4 = n – (3 + 1) = (n + n) – 8 = 24 – (n +7) = 14 + (n + 13) =

16 Check Did you remember to do the operations in the parentheses () first?

17 Insert parentheses to make each equation true 11 – = – 8 = 13 8 – = – 2 = – (5 + 1) = 5 15 – (10 – 8) = 13 (8 – 2) +7 = 13 (9 + 3) – 2 = 10
