### About the Number 2112 (two thousand one hundred twelve)

This nBAB about the number `2112` came about as a result of a nBAB about the number 31. The nBAB about number 31 prompted nBABs to be created for the numbers 80, 30, and 70 (in that order). The nBAB about the number 70 was BAB# `2112`. This in of itself would not have prompted MathBabbler to create this nBAB, but `2112` was the name of one of MathBabbler's favorite albums when he was going to college. Note: The Canadian band Rush released the album `2112` in 1976.

What's a happy number?

```   "A happy number is defined by the following process. Starting
with any positive integer, replace the number by the sum of
the squares of its digits, and repeat the process until the
number equals 1 (where it will stay), or it loops endlessly
in a cycle which does not include 1. Those numbers for which
this process ends in 1 are happy numbers while those that do
not end in 1 are unhappy numbers."

```   2^2 + 1^2 + 1^2 + 2^2 = 10
1^0 + 0^1 = 1
