Let's think step by step.
- Difference = 574 - 139.
- 574 - 139
- ones: 4 - 9 can't, borrow -> 14 - 9 = 5, write 5
- tens: 6 - 3 = 3, write 3
- hundreds: 5 - 1 = 4, write 4
- written: 5 3 4 -> answer 435
Answer: 435


Question: 'I have read 56 pages of this 300-page book.' 'I have read 75 pages.' How many pages have they not read between them?
Let's think step by step.
- Pages read together = 56 + 75.
- 6 + 5 = 11 -> write 1, carry 1

- carry 1 -> write 1
- written: 1 3 1 -> answer 131
- Pages left = 300 - 131.
- 300 - 131
- ones: 0 - 1 can't, borrow -> 10 - 1 = 9, write 9
- tens: 9 - 3 = 6, write 6
- hundreds: 2 - 1 = 1, write 1

Question: Dinner costs $72.86. You add a 10% tip and pay $100.00. How much change?
Let's think step by step.
- Bill is 7286 cents.
- 10% tip = 7286 / 10 = 728.
- Total = 7286 + 728.
- 6 + 8 = 14 -> write 4, carry 1
- 8 + 2 + 1 = 11 -> write 1, carry 1
- 2 + 7 + 1 = 10 -> write 0, carry 1
- 7 + 0 + 1 = 8 -> write 8
- written: 4 1 0 8 -> answer 8014
- Change = 10000 - 8014.
- 10000 - 8014
- ones: 0 - 4 can't, borrow -> 10 - 4 = 6, write 6
- tens: 9 - 1 = 8, write 8
- hundreds: 9 - 0 = 9, write 9
- thousands: 9 - 8 = 1, write 1

Question: A bus leaves at 8:32. The ride takes 38 minutes and the walk home takes 15 minutes. What time do you arrive?
Let's think step by step.
- Total travel minutes = 38 + 15.
- 8 + 5 = 13 -> write 3, carry 1
- 3 + 1 + 1 = 5 -> write 5
- written: 3 5 -> answer 53
- Leave at 8:32. Add 53 minutes: 32 + 53 = 85 minutes.
- 85 is more than 60, so subtract 60: 85 - 60 = 25, and add 1 hour: 8 + 1 = 9.
Answer: 9:25

- 4 + 1 = 5 -> write 5
- written: 4 5 -> answer 54
- Leave at 9:05. Add 54 minutes: 5 + 54 = 59 minutes.
Answer: 9:59

Question: A garden is 11 meters by 10 meters. Fencing costs $3 per meter. How much to fence it?
Let's think step by step.
- Perimeter = 11 + 10 + 11 + 10.
- 1 + 0 = 1 -> write 1

- written: 1 2 -> answer 21
- 1 + 1 = 2 -> write 2
- 2 + 2 = 4 -> write 4
- written: 2 4 -> answer 42
