Math

First of all, it is helpful to put a \$ so it doesnt take it as $\LaTeX$. If Joe owed Mike 49 dollars on friday, and he paid 23 dollars from it, then you use the 2 numbers, 49 and 23 and make a expression. The expression would be $49-23$. And $49-23=26$.

in this case the formula would be what Joe owes subtracted by how many dollars Joe paid Mike, so 49-23=26

also @cryptoaops, I'm pretty sure you know me. I'm dd0

btw, I upvoted your post. 

Thanks, guys   !!!
