Here are the solutions to the mental maths problems: Step 1: Solve 5,000 - 4,075. 5,000 - 4,075 = 925 The answer is 925. Step 2: Solve 5 - 7. 5 - 7 = -2 The answer is -2. Step 3: Solve [3]8 - 2. First, find the cube root of 8. [3]8 = 2 Then, subtract 2. 2 - 2 = 0 The answer is 0. Step 4: Solve -7 + 10. -7 + 10 = 3 The answer is 3. Step 5: Solve 8 - (-9). Subtracting a negative number is the same as adding its positive counterpart. 8 - (-9) = 8 + 9 = 17 The answer is 17. Step 6: Solve 12 × 13. 12 × 13 = 156 The answer is 156. Step 7: Solve (-2)^3. (-2)^3 = (-2) × (-2) × (-2) (-2) × (-2) = 4 4 × (-2) = -8 The answer is -8. Step 8: Solve (1)/(3) × (9)/(2). Multiply the numerators and the denominators. (1)/(3) × (9)/(2) = (1 × 9)/(3 × 2) = (9)/(6) Simplify the fraction by dividing both numerator and denominator by their greatest common divisor, which is 3. (9)/(6) = (9 ÷ 3)/(6 ÷ 3) = (3)/(2) The answer is (3)/(2). Step 9: Solve 654 + 246. 654 + 246 = 900 The answer is 900. Step 10: Solve 4^3. 4^3 = 4 × 4 × 4 4 × 4 = 16 16 × 4 = 64 The answer is 64.
