GitQuest Days 12 & 13: Addition, Subtraction, Multiplication
Today I completed addition and subtraction. I also included a multiplication function. All combinations of positives, negatives, and zero are supported. Leading zeros are removed, and there is no such thing as negative zero. The multiplication algorithm is pretty naive and what one would learn in grade school. I didn't think the integers would be big enough to require more sophisticated algorithms. They are big-enough integers. Maybe at a later time.
Next up, division and modulus. Check it out.
