Estimate the answer: Same as above

Perform the calculation:

40 3 × 10 7 ------ 400 30 280 21 ------ 731 Verify your answer: Check that the answer is reasonable and accurate.

Calculate 43 × 17

Perform the calculation: 432 - 24 = 408, 408 - 24 = 384, ... 384 - 24 = 360, ... 18 times.

Perform the calculation: 432 ÷ 24 = 432 × (1/24) = 432 × (5/120) = 18

Visualize the numbers: Imagine a rectangle with sides 40 and 20, and add 3 and -3 to account for 43 and -7 to account for 17. Estimate the answer: 400 ÷ 20 = 20

Perform the calculation: 43 × 17 = (40 + 3) × (20 - 3) = 40 × 20 - 40 × 3 + 3 × 20 - 3 × 3 = 800 - 120 + 60 - 9 = 731
