There may be hundreds of equations there.

As a side note to the topic in discussion, I'd like to point out that I hope those hundreds of equations are better written than the first one, which is the quadratic formula, and it reads something like x=(-b+-√b^2-4xaxc)/2xa. At least in my android mobile. Holy crap!
