Question: A bus leaves at 10:35. The ride takes 20 minutes and the walk home takes 9 minutes. What time do you arrive?
Let's think step by step.
- Total travel minutes = 20 + 9.
- 0 + 9 = 9 -> write 9
- 2 + 0 = 2 -> write 2
- written: 9 2 -> answer 29
- Leave at 10:35. Add 29 minutes: 35 + 29 = 64 minutes.
- 64 is more than 60, so subtract 60: 64 - 60 = 4, and add 1 hour: 10 + 1 = 11.
Answer: 11:04


Question: Class A collected 189 cans and class B collected 100 cans. How many more did class A collect?
Let's think step by step.
- Difference = 189 - 100.
- 189 - 100
- ones: 9 - 0 = 9, write 9
- tens: 8 - 0 = 8, write 8
- hundreds: 1 - 1 = 0, write 0
- written: 9 8 0 -> answer 89
Answer: 89


Question: A bus leaves at 7:40. The ride takes 24 minutes and the walk home takes 5 minutes. What time do you arrive?
Let's think step by step.
- Total travel minutes = 24 + 5.
- 4 + 5 = 9 -> write 9
- 2 + 0 = 2 -> write 2
- written: 9 2 -> answer 29
- Leave at 7:40. Add 29 minutes: 40 + 29 = 69 minutes.
- 69 is more than 60, so subtract 60: 69 - 60 = 9, and add 1 hour: 7 + 1 = 8.

Question: 'I have read 31 pages of this 350-page book.' 'I have read 27 pages.' How many pages have they not read between them?
Let's think step by step.
- Pages read together = 31 + 27.
- 1 + 7 = 8 -> write 8
- 3 + 2 = 5 -> write 5
- written: 8 5 -> answer 58
- Pages left = 350 - 58.
- 350 - 58
- ones: 0 - 8 can't, borrow -> 10 - 8 = 2, write 2
- tens: 4 - 5 can't, borrow -> 14 - 5 = 9, write 9

Question: A car drives 50 miles per hour for 4 hours. How far does it travel?
Let's think step by step.
- Distance = speed * time = 50 * 4.
- 50 * 4
- 0 * 4 = 0 -> write 0
- 5 * 4 = 20 -> write 0, carry 2
- carry 2 -> write 2
- written: 0 0 2 -> answer 200
Answer: 200 miles


Question: A bus leaves at 7:11. The ride takes 26 minutes and the walk home takes 5 minutes. What time do you arrive?

- 6 + 5 = 11 -> write 1, carry 1
- 2 + 0 + 1 = 3 -> write 3
- written: 1 3 -> answer 31
- Leave at 7:11. Add 31 minutes: 11 + 31 = 42 minutes.
Answer: 7:42


Question: A bus leaves at 8:20. The ride takes 33 minutes and the walk home takes 11 minutes. What time do you arrive?
Let's think step by step.
- Total travel minutes = 33 + 11.
- 3 + 1 = 4 -> write 4
- 3 + 1 = 4 -> write 4
- written: 4 4 -> answer 44
- Leave at 8:20. Add 44 minutes: 20 + 44 = 64 minutes.
- 64 is more than 60, so subtract 60: 64 - 60 = 4, and add 1 hour: 8 + 1 = 9.
