Question: A bus leaves at 9:42. The ride takes 33 minutes and the walk home takes 8 minutes. What time do you arrive?
Let's think step by step.
- Total travel minutes = 33 + 8.
- 3 + 8 = 11 -> write 1, carry 1
- 3 + 0 + 1 = 4 -> write 4
- written: 1 4 -> answer 41
- Leave at 9:42. Add 41 minutes: 42 + 41 = 83 minutes.
- 83 is more than 60, so subtract 60: 83 - 60 = 23, and add 1 hour: 9 + 1 = 10.
Answer: 10:23


Question: A bus leaves at 10:27. The ride takes 26 minutes and the walk home takes 15 minutes. What time do you arrive?
Let's think step by step.
- Total travel minutes = 26 + 15.
- 6 + 5 = 11 -> write 1, carry 1
- 2 + 1 + 1 = 4 -> write 4
- written: 1 4 -> answer 41
- Leave at 10:27. Add 41 minutes: 27 + 41 = 68 minutes.
- 68 is more than 60, so subtract 60: 68 - 60 = 8, and add 1 hour: 10 + 1 = 11.
Answer: 11:08


Question: Dinner costs $38.51. You add a 10% tip and pay $60.00. How much change?
Let's think step by step.
- Bill is 3851 cents.
- 10% tip = 3851 / 10 = 385.
- Total = 3851 + 385.
- 1 + 5 = 6 -> write 6
- 5 + 8 = 13 -> write 3, carry 1
- 8 + 3 + 1 = 12 -> write 2, carry 1
- 3 + 0 + 1 = 4 -> write 4
- written: 6 3 2 4 -> answer 4236
- Change = 6000 - 4236.
- 6000 - 4236
- ones: 0 - 6 can't, borrow -> 10 - 6 = 4, write 4
- tens: 9 - 3 = 6, write 6
- hundreds: 9 - 2 = 7, write 7
- thousands: 5 - 4 = 1, write 1
- written: 4 6 7 1 -> answer 1764
Answer: $17.64

Let's think step by step.
- Difference = 844 - 700.
- 844 - 700
- ones: 4 - 0 = 4, write 4

- hundreds: 8 - 7 = 1, write 1
- written: 4 4 1 -> answer 144
Answer: 144


Question: A car drives 58 miles per hour for 5 hours. How far does it travel?
Let's think step by step.
- Distance = speed * time = 58 * 5.
- 58 * 5
- 8 * 5 = 40 -> write 0, carry 4
- 5 * 5 + 4 = 29 -> write 9, carry 2
- carry 2 -> write 2
- written: 0 9 2 -> answer 290
Answer: 290 miles
