The pattern behind the list
Look at the last digit of each answer. From 8 × 1 to 8 × 10 it goes like this, and then the same pattern repeats every ten facts all the way up to 8 × 40:
- 8
- 6
- 4
- 2
- 0
- 8
- 6
- 4
- 2
- 0
Working out big facts
You do not need to learn all 40 facts by heart. Use the method for the 8 times table instead: Times 8 means doubling three times in a row.
Double 40 three times: 40 → 80 → 160 → 320.
8 × 40 = 2 × 2 × 2 × 40 = 320
