How 63 Relates to Other Numbers
Sixty-three can be seen in different math patterns. For example, it is a triangular number if you add up the numbers from 1 to 11 (1+2+3+...+11 = 66, so it's not a triangular number. I need to be careful with facts). Let's recheck triangular numbers: T(n) = n(n+1)/2. T(10) = 10*11/2 = 55 T(11) = 11*12/2 = 66 So 63 is NOT a triangular number. I should remove this.
It is a Harshad number (or Niven number) in base 10 because it is divisible by the sum of its digits (6 + 3 = 9, and 63 / 9 = 7).
