When writing a mathematical essay (much like fishing) you need a hook, line and sinker.  Ponder on a math problem and don’t say you never heard one before “if I gave you a penny a day and doubled it everyday, how much would you have by the end of the month?”  Got a case of the dumb dumbs? –Don’t feel bad at one point or another, everybody’s been there.  Math essays are not that difficult.  The fundamentals of this gender of essay are the same as the basic five paragraph essay, except the game changes.  You want to produce a quick answer making the punch line descriptive to how that answer was obtained.  The conclusion was a reflection of the solution not the answer.  With a little thought, average Joe and simple Jane can do this math, but in the essay you want to give out the answer to this question fast enough, but not before you’re readers have thought about it…aim for about the second paragraph or so, that’s your hook.
