Your goal is to add two input numbers without using any of the following math operators:
Additionally, you can't use any built-in functions that are designed to replace those math operators.
Smallest code (in number of bytes) wins.
Most of the programs i've seen either concatenate two arrays containing their numbers, or make
first numberof a character, append
second numbercharacters, then count them all.
