Here are the solutions to the questions: 2.4 Solve this word sum and show your calculations. Jack's scores in five successive rounds were 25, -5, -10, 15 and 10. Step 1: Sum all the scores to find the total. Total = 25 + (-5) + (-10) + 15 + 10 Step 2: Group positive and negative numbers. Total = (25 + 15 + 10) + (-5 - 10) Step 3: Perform the additions and subtractions. Total = 50 + (-15) Total = 50 - 15 Total = 35 Jack's total at the end was 35. 35 QUESTION 3 3.1 Calculate: (10 - 6)^3 Step 1: Perform the operation inside the parentheses. 10 - 6 = 4 Step 2: Cube the result. 4^3 = 4 × 4 × 4 4^3 = 16 × 4 4^3 = 64 64 3.2 Calculate: sqrt(24+1) + sqrt(10-1) Step 1: Perform the operations inside each square root. sqrt(24+1) = sqrt(25) sqrt(10-1) = sqrt(9) Step 2: Calculate the square root of each number. sqrt(25) = 5 sqrt(9) = 3 Step 3: Add the results. 5 + 3 = 8 8 3 done, 2 left today.
