The pattern behind the list
Look at the last digit of each answer. From 2 × 1 to 2 × 10 it goes like this, and then the same pattern repeats every ten facts all the way up to 2 × 50:
- 2
- 4
- 6
- 8
- 0
- 2
- 4
- 6
- 8
- 0
Working out big facts
You do not need to learn all 50 facts by heart. Use the method for the 2 times table instead: Times 2 means doubling: add the number to itself.
Times 2 means doubling: 50 + 50 = 100.
2 × 50 = 50 + 50 = 100
