Answer Key
Click to reveal answers
1. -7 + 12 = 5
2. -15 - (-8) = -15 + 8 = -7
3. -6 x 9 = -54
4. -48 / (-6) = 8
5. |-23| = 23
6. -8, -3, 0, 2, 5
7. 8 - (-12) = 8 + 12 = 20 degrees
8. -4 + (-15) = -19 (multiply first)
9. -45 + 20 - 15 = -40 feet
10. b must be negative (positive x negative = negative)
