How it works
Both sides of the equals make the same number.
Work out the side you can, then find what makes the other side match.
Use times facts or division to find the missing number.
Worked examples
Work out one side
- ? = 10 × 4
- 10 × 4 on one side.
- The other side must be the same.
- So the answer is 40.
The answer is the missing number
- 9 × 5 = ?
- Work out 9 × 5.
- That is the missing number.
- So the answer is 45.
Both sides have a times
- 3 × 4 = ? × 6
- 3 × 4 = 12, so the other side is 12.
- What times 6 makes 12?
- So the answer is 2.
