Question 1

What is -7 + 15?

Accepted Answer

8

Answer

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.

Question 2

What is the value of -4 × (-3)?

Accepted Answer

12

Answer

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

Question 3

What is the absolute value of -9?

Accepted Answer

9

Answer

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

Question 4

Evaluate: 5 - (-8)

Accepted Answer

13

Answer

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

Question 5

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

Accepted Answer

-5, -2, 0, 3

Answer

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