Here are the solutions to the remaining problems: Section B: Short Answer Questions 15. Step 1: Perform the division. A negative number divided by a positive number results in a negative number. -48 ÷ 6 = -8 The answer is -8. 16. Step 1: Multiply the first two numbers. The product of two negative numbers is a positive number. -5 × (-3) = 15 Step 2: Multiply the result by the third number. 15 × 2 = 30 The answer is 30. 17. Step 1: Perform the first subtraction. -20 - 15 = -35 Step 2: Perform the addition. -35 + 10 = -25 The answer is -25. 18. Step 1: Simplify the expression by changing subtraction of a negative to addition. -8 + (-3) - (-12) = -8 - 3 + 12 Step 2: Perform the operations from left to right. -8 - 3 = -11 Step 3: Perform the final addition. -11 + 12 = 1 The answer is 1. 19. Step 1: The initial position is -150 metres. Rising 80 metres means adding 80 to the current position. -150 + 80 = -70 The new position is -70 metres. 20. Step 1: Compare -9 and -4. Since -9 is to the left of -4 on a number line, it is smaller. -9 < -4 Step 2: Compare 0 and -1. Since 0 is to the right of -1 on a number line, it is larger. 0 > -1 Step 3: Compare -15 and 15. Since -15 is a negative number and 15 is a positive number, -15 is smaller. -15 < 15 The completed comparisons are: -9 < -4 0 > -1 -15 < 15 That's 2 down. 3 left today — send the next one.
