Most multiplication tables of 1-11 follow a pattern (Excluding 3 and 7). This helps me to know how a number might be divisible by something, or help me remember a multiplication table if I forget it.
- 1: Pretty obvious
- 2: The one’s place digit will end in 0, 2, 4, 6, 8
- 4: The one’s place digit only goes in the order of 0, 4, 8, 2, 6
- 5: The one’s place digit can only be 0 or 5
- 6: The one’s place digit can only be 0, 6, 2, 8, 4
- 8: Follows the one’s place digit restriction of 4, just in a different pattern.
- 9: Where N < 10, adding (N * 9)'s digits together will always make 9.
- 10: The one’s digit is always 0
- 11: Where N < 10, (N * 11)'s digits are always the same.
- 12: Where N < 5, (N * 12)'s one’s digit is double the ten’s digit.
