  1. What is -7 + 15?

    Answer: 8

    Start at -7 on the number line and move 15 steps in the positive direction: -7 + 15 = 8. When adding a positive number to a negative number, subtract the smaller absolute value from the larger and keep the sign of the larger.

  2. What is the value of -4 × (-3)?

    Answer: 12

    The product of two negative numbers is always positive. -4 × -3 = +12. The rule: negative × negative = positive.

  3. What is the absolute value of -9?

    Answer: 9

    Absolute value represents the distance from zero on the number line, which is always non-negative. |-9| = 9.

  4. Evaluate: 5 - (-8)

    Answer: 13

    Subtracting a negative number is the same as adding the positive: 5 - (-8) = 5 + 8 = 13.

  5. Which list places these numbers in order from least to greatest: -2, 0, -5, 3?

    Answer: -5, -2, 0, 3

    On the number line, -5 is furthest left (least), then -2, then 0, then 3 (greatest). More negative = smaller value.

  6. What is (-18) ÷ (-6)?

    Answer: 3

    Dividing two numbers with the same sign yields a positive result: (-18) ÷ (-6) = +3.
