Q3. b) 24
Explanation: Negative x Negative = Positive, so (-4) x (-6) = 24
Q4. c) -5
Explanation: On a number line, numbers decrease as we move left, so -5 lies to the left of -3
Q5. b) -4
Explanation: (-36) divided by 9 = -4, since a negative number divided by a positive number gives a negative result
Q6. Negative
Q7. 0
Q8. Negative
Q9. -24

Q11. Position of submarine = -350 + 120 = -230 metres
The new position of the submarine is 230 metres below sea level.
Q12. (-5) x 3 = -15
(-2) x (-4) = 8
(-15) + 8 = -7
The value is -7.
Q13. Three negative integers greater than -10 are: -9, -7, -5
Any three integers from -9 to -1 are acceptable answers.
Q14. Left Hand Side: (-12) x [3 + (-5)] = (-12) x (-2) = 24
Right Hand Side: [(-12) x 3] + [(-12) x (-5)] = (-36) + (60) = 24
Since LHS = RHS = 24, the distributive property is verified.
Q15. Temperature on Monday = -4 degree Celsius
Temperature dropped by 3 degrees means we subtract 3.
Temperature on Tuesday = (-4) + (-3) = -7 degree Celsius
