- tens: 6 - 4 = 2, write 2
- hundreds: 6 - 5 = 1, write 1
- written: 9 2 1 -> answer 129
Answer: 129


Question: A bus leaves at 8:12. The ride takes 22 minutes and the walk home takes 10 minutes. What time do you arrive?
Let's think step by step.
- Total travel minutes = 22 + 10.
- 2 + 0 = 2 -> write 2
- 2 + 1 = 3 -> write 3
- written: 2 3 -> answer 32
- Leave at 8:12. Add 32 minutes: 12 + 32 = 44 minutes.
Answer: 8:44


Question: Dinner costs $22.40. You add a 10% tip and pay $40.00. How much change?
Let's think step by step.
- Bill is 2240 cents.
- 10% tip = 2240 / 10 = 224.
- Total = 2240 + 224.
- 0 + 4 = 4 -> write 4
- 4 + 2 = 6 -> write 6
- 2 + 2 = 4 -> write 4
- 2 + 0 = 2 -> write 2
- written: 4 6 4 2 -> answer 2464
- Change = 4000 - 2464.
- 4000 - 2464
- ones: 0 - 4 can't, borrow -> 10 - 4 = 6, write 6
- tens: 9 - 6 = 3, write 3
- hundreds: 9 - 4 = 5, write 5
- thousands: 3 - 2 = 1, write 1
- written: 6 3 5 1 -> answer 1536
Answer: $15.36


Question: If 4 shirts cost 20 dollars, how much do 3 shirts cost?
Let's think step by step.
- 4 cost 20 dollars, so 1 costs 5 dollars.
- 3 * 5
- 3 * 5 = 15 -> write 5, carry 1
- carry 1 -> write 1
- written: 5 1 -> answer 15
Answer: 15 dollars


Question: You have 34 cookies and pack them 8 per bag. How many full bags, and how many cookies are left over?
Let's think step by step.
- Keep subtracting 8 until too little remains.
- 34 - 8
- ones: 4 - 8 can't, borrow -> 14 - 8 = 6, write 6
- tens: 2 - 0 = 2, write 2
- written: 6 2 -> answer 26
- 26 - 8
- ones: 6 - 8 can't, borrow -> 16 - 8 = 8, write 8
- tens: 1 - 0 = 1, write 1
- written: 8 1 -> answer 18
- 18 - 8
- ones: 8 - 8 = 0, write 0
- tens: 1 - 0 = 1, write 1
- written: 0 1 -> answer 10
- 10 - 8
- ones: 0 - 8 can't, borrow -> 10 - 8 = 2, write 2
- tens: 0 - 0 = 0, write 0
- written: 2 0 -> answer 2
- Subtracted 8 exactly 4 times; 2 left, which is less than 8.
Answer: 4 bags, 2 leftover


Question: A bus leaves at 8:16. The ride takes 22 minutes and the walk home takes 15 minutes. What time do you arrive?
Let's think step by step.
- Total travel minutes = 22 + 15.
- 2 + 5 = 7 -> write 7
- 2 + 1 = 3 -> write 3
- written: 7 3 -> answer 37
- Leave at 8:16. Add 37 minutes: 16 + 37 = 53 minutes.
Answer: 8:53


Question: A bus leaves at 9:37. The ride takes 34 minutes and the walk home takes 10 minutes. What time do you arrive?
Let's think step by step.
- Total travel minutes = 34 + 10.
- 4 + 0 = 4 -> write 4
- 3 + 1 = 4 -> write 4
- written: 4 4 -> answer 44
- Leave at 9:37. Add 44 minutes: 37 + 44 = 81 minutes.
- 81 is more than 60, so subtract 60: 81 - 60 = 21, and add 1 hour: 9 + 1 = 10.
Answer: 10:21
