Before you start

Move along the whole numbers. Notice that each one has a next one, and that only zero has nothing before it.

The line stops at 0 on the left because that is where the whole numbers start — but it never has to stop on the right.

1.Match each calculation to its answer.
- 25 × 4
- 25 + 4
- 25 - 4
- 100 ÷ 4
- 4 × 4
- 21
- 16
- 100
- 29
- 25
2.Which pair gives the same answer both ways round?
- a) 9 - 4 and 4 - 9

- c) 9 - 4 and 4 + 9
- d) 9 ÷ 4 and 4 ÷ 9
3.Tap the whole number that is halfway between 40 and 60.
