Wow. Two thoughts occur to me:
A) You're only 43? Is that in hexadecimal, or what? Could you supply your birth year and let me do the math for you? You do know that you have to borrow if the subtrahend digit is bigger than the minuend digit, right?
-and-
2) How the hell you made it to 43 with all those get-offs defies logic.
