Question: A bus leaves at 9:32. The ride takes 38 minutes and the walk home takes 6 minutes. What time do you arrive?
Let's think step by step.
- Total travel minutes = 38 + 6.

Question: A garden is 9 meters by 12 meters. Fencing costs $3 per meter. How much to fence it?
Let's think step by step.
- Perimeter = 9 + 12 + 9 + 12.

- written: 1 2 -> answer 21
- 1 + 1 = 2 -> write 2
- 2 + 2 = 4 -> write 4
- written: 2 4 -> answer 42
- Fence cost = 42 * 3.
- 42 * 3
- 2 * 3 = 6 -> write 6
- 4 * 3 = 12 -> write 2, carry 1
