We worked on the first three questions:
We thought of how we could make the four numbers add up to a multiple of 4 and used trial and error.
- 11, 5, 5
- 5, 6, 10, 5
- 5, 8, 12, 25, 70
For the third question, we actually worked from right to left because 243 was a large number and every missing number affected the next missing number.
