The 3 times table involves adding 3 repeatedly
Here is the 3 times table:
1 × 3 = 3
2 × 3 = 6
3 × 3 = 9
4 × 3 = 12
5 × 3 = 15
6 × 3 = 18
7 × 3 = 21
8 × 3 = 24
9 × 3 = 27
10 × 3 = 30
More than 10:
11 × 3 = 33
12 × 3 = 36
Repeated Addition[]
3 = 3
3 + 3 = 6
3 + 3 + 3 = 9
3 + 3 + 3 + 3 = 12
3 + 3 + 3 + 3 + 3 = 15
3 + 3 + 3 + 3 + 3 + 3 = 18
3 + 3 + 3 + 3 + 3 + 3 + 3 = 21
3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 = 24
3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 = 27
3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 = 30
3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 = 33
3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 = 36
Tips & Tricks[]
- Add the number's digits up. If the sum equals 3 or a multiple of 3, it is divisible by 3 (930 = 9 + 3 + 0 = 12. Divisible by 9. 550 = 5 + 5 + 0 = 10. Not divisible by 3) (This also works for the 9 times table, except if it equals 9 or a multiple of 9, it is divisible by 9)
- Review the commutative property quickly (5 × 3 = 3 × 5)
