Here are the solutions to the mathematics problems from the image. EXERCISE 4: Use any method to calculate the following. 1. Step 1: Add the ones digits: 2 + 1 = 3. Step 2: Add the tens digits: 7 + 8 = 15. Write 5, carry 1. Step 3: Add the hundreds digits: 5 + 9 + 1 (carry) = 15. Write 5, carry 1. Step 4: Add the thousands digits: 3 + 2 + 1 (carry) = 6. 3572 + 2981 = 6553 3. Step 1: Add the ones digits: 5 + 5 = 10. Write 0, carry 1. Step 2: Add the tens digits: 1 + 8 + 1 (carry) = 10. Write 0, carry 1. Step 3: Add the hundreds digits: 7 + 2 + 1 (carry) = 10. Write 0, carry 1. Step 4: Add the thousands digits: 6 + 0 + 1 (carry) = 7. 6715 + 285 = 7000 5. Step 1: Add the ones digits: 2 + 5 = 7. Step 2: Add the tens digits: 6 + 2 = 8. Step 3: Add the hundreds digits: 5 + 8 = 13. Write 3, carry 1. Step 4: Add the thousands digits: 4 + 3 + 1 (carry) = 8. 4562 + 3825 = 8387 7. Step 1: Add the ones digits: 7 + 4 = 11. Write 1, carry 1. Step 2: Add the tens digits: 4 + 8 + 1 (carry) = 13. Write 3, carry 1. Step 3: Add the hundreds digits: 9 + 3 + 1 (carry) = 13. 947 + 384 = 1331 9. Step 1: Add the ones digits: 6 + 3 = 9. Step 2: Add the tens digits: 7 + 5 = 12. Write 2, carry 1. Step 3: Add the hundreds digits: 3 + 7 + 1 (carry) = 11. Write 1, carry 1. Step 4: Add the thousands digits: 8 + 4 + 1 (carry) = 13. 8376 + 4753 = 13129 EXERCISE 5: Replace the letters with the correct numbers. The image provides the solutions for 'a' and 'b' in the number pyramid examples. For 'a', the calculation shown is 3231 - 1647 = 1584. This is correct. For 'b', the calculation shown is 2131 + 1252 = 3383. This is correct. 3 done, 2 left today. You're making progress.
