BSEP Integers and Signed Number Operations Practice

Question 1: What is -7 + 15?

8 (Correct answer)
-8
22
-22

Correct 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.

Question 2: What is the value of -4 × (-3)?

12 (Correct answer)
-12
7
-7

Correct answer: 12

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?

9 (Correct answer)
-9
0
1/9

Correct answer: 9

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

Question 4: Evaluate: 5 - (-8)

13 (Correct answer)
-3
3
-13

Correct answer: 13

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?

-5, -2, 0, 3 (Correct answer)
-2, -5, 0, 3
0, -2, -5, 3
3, 0, -2, -5

Correct 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.

Question 6: What is (-18) ÷ (-6)?

3 (Correct answer)
-3
12
-12

Correct answer: 3

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