The pattern behind the list
Look at the last digit of each answer. From 24 × 1 to 24 × 10 it goes like this, and then the same pattern repeats every ten facts all the way up to 24 × 20:
- 4
- 8
- 2
- 6
- 0
- 4
- 8
- 2
- 6
- 0
Working out big facts
You do not need to learn all 20 facts by heart. Use the method for the 24 times table instead: 24 is double 12, so work out the 12s answer and double it.
Work out 12 × 20 = 240, then double it: 240 + 240 = 480.
24 × 20 = 2 × 240 = 480
