Rewrite the following expressions using the associative property. Do not evaluate the expressions; in other words, don't come up with the final answer, but just rewrite them.

1. (1 + 2) + 3

2. 1 + (2 + 3)

3. 2 • (3 • 4)

4. (2 • 3) • 4



Rewrite the following expressions using the commutative property. Do not evaluate the expressions; in other words, don't come up with the final answer, but just rewrite them.

5. 2 • 3

6. 1 + 2

7. 2(3 + x)

8. 3 + 4x



Rewrite the following expressions using the distributive property. Evaluate the expression to their simplest form after distributing.

9. 4(3 + 2)

10. –2(5 + x)

11. 3(10 – y)

12. –3(4 – x)



Identify which property is true in each of the following problems.

13. Why is it true that 3 + 2 = 2 + 3?

14. Why is it true that x • y = y • x?

15. Why is it true that –4(3 – y) = –12 + 4y?

16. Why is it true that (2 + x) + y = 2 + (x + y)?
