At first, I thought the OP was putting up a calculator from some kind of Bowflex machine given the thread title. Now that I know it's just for normal olympic bar and plates. WTF?
Seriously, WTF man?
If there's anyone out there having trouble adding up the weight in the gym, perhaps your money would be better spent on math books and a tutor rather than gym fees and supplements.
Hopefully Print will show up soon to punch you in the face.
