ASSOCIATIVE/COMMUTATIVE/DISTRIBUTIVE/IDENTITY/INVERSE Properties Worksheet
Directions:
The following expressions have been simplified. Tell which property was
used in each step. As always, SHOW ALL WORK TO RECEIVE ANY CREDIT.
ex.) 5 (2 + x) - 8x
=
(10 + 5x) - 8x
=
Distributive Property
10 + (5x – 8x)
=
Associative Property
10 + -3x
=
-3x + 10
1.)
2.)
Commutative Property
3a – 5b + 7a=
3a + 7a - 5b=
________________________
10a – 5b
________________________
23 + 5c + 7d – c – d - 27=
23 - 27 + 5c - c+ 7d – d =
3.)
Combining Like Terms
________________________
-4 + 4c + 6d
________________________
4c + 6d - 4
________________________
3 (2 + y) - 4y=
(6 + 3y) - 4y =
________________________
6 + (3y - 4y) =
________________________
6 + -y
________________________
-y + 6
________________________
Directions:
Simplify the expression and tell which property you used for each step.
Hint: you should have about as many steps as there are lines. Use #1, 2,
and 3 as examples.
4.)
3 (4 + r) =

Directions:
Identify the properties (distributive, commutative, associative, identity
or inverse) that make the below statements true.
8.) (y + 4) – 7 = y + (4
- 7)
9.)
7x + 0 = 7x
