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.
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.
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.
Evaluate: 5 - (-8)
Answer: 13
Subtracting a negative number is the same as adding the positive: 5 - (-8) = 5 + 8 = 13.
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.
What is (-18) ÷ (-6)?
Answer: 3
Dividing two numbers with the same sign yields a positive result: (-18) ÷ (-6) = +3.
