They all seem to be using a very mathematical sort of dialect (thus we can see... or to find x we need to complete a square, with no word on how one might accomplish this \"completion of a square\"), which in my opinion is counterproductive--the very people needing help with math are the very ones who won't understand the language! Anyways, that's a bit long-winded, so here's the problem:\r
