I just balanced my checkbook, but instead of using a calculator I did the math on paper. I'm kind of ashamed to say that it took me a couple of tries to remember how to do subtraction in numbers that big.

"Carry the one....no wait, do I carry the one? Where does the one go? I THINK I carry the one. Wait, if I do that then I have more money than I started out with. Something's not right."

I got it eventually. The subtraction gears in my head haven't been used since about fourth grade. Pretty rusty.

What always got me in trouble was decimals and percentages. I can't for the life of me figure out how to calculate a 15% tip on a restaurant bill. Do any of you guys have any handy tips on that to get my inner calculator working again?

math, money
