How it works
Nines: ten times, then one less. 3 × 9 is 3 × 10 − 3.
Eights: double, double, double. Sevens: five, then two more.
Turn a fact round if it helps: 8 × 3 = 3 × 8.
Worked examples
Nines
- 3 × 9 = ?
- Think 3 × 10 = 30.
- Take one 3 off: 30 − 3 = 27.
- So the answer is 27.
Division with nines
- 81 ÷ 9 = ?
- Think what times 9 makes 81.
- 9 × 9 = 81.
- So the answer is 9.
Eights
- 8 × 3 = ?
- Double 3 is 6. Double 6 is 12. Double 12 is 24.
- So 8 × 3 = 24.
- So the answer is 24.
