The pattern behind the list
Look at the last digit of each answer. From 4 × 1 to 4 × 10 it goes like this, and then the same pattern repeats every ten facts all the way up to 4 × 100:
- 4
- 8
- 2
- 6
- 0
- 4
- 8
- 2
- 6
- 0
Working out big facts
You do not need to learn all 100 facts by heart. Use the method for the 4 times table instead: Times 4 means doubling twice: double the number, then double the answer.
Double 100 to get 200, then double again to get 400.
4 × 100 = 2 × 200 = 400
