The pattern behind the list
Look at the last digit of each answer. From 7 × 1 to 7 × 10 it goes like this, and then the same pattern repeats every ten facts all the way up to 7 × 40:
- 7
- 4
- 1
- 8
- 5
- 2
- 9
- 6
- 3
- 0
Working out big facts
You do not need to learn all 40 facts by heart. Use the method for the 7 times table instead: Split 7 into 5 and 2: work out the 5s and the 2s, then add them.
Split 7 into 5 and 2. 5 × 40 = 200 and 2 × 40 = 80, so 7 × 40 = 200 + 80 = 280.
7 × 40 = 200 + 80 = 280
