ANSWER KEY:

Adding Like Terms:

1. 6 + 2 = 8a5
2. -2 + 2= 0p
3. 23 + 11 = 34q12
4. 3 + 1 +10 = 14b2
5.  10 + 5 = 15a3
6. -9 + 8 = -1 + 13= 12t8
7. 15 + 12 + 17 = 44y4

Subtracting Like Terms:

1. 11 - 9 = 2g9
2. 4 -5 = -16
3. 18 – 13 = 5 n4
4. 1+ -7 = -6h2
5. -8 –1 – 1 = -10z3
6. 16-9 = 7-1 = 6 t15
7. 3 – 4 = -1 + -7 = -8 r2

Division problem:

1. 5 * 6 = 30 (+, + = +)
2. -4 * 9 = -36 (-, + = -)
3. 24 ÷ -6 = -4 (+, - = -)
4. -32 ÷ -8 = 4 (-, - = +)
