Reaper
I got 9th place in the longest game of Reaper, Game 18, and 16th in Game 19. I also managed to get a score of 2797 in Boxy, the temporary game that existed on October 4th.
negativebplusorminus
My username is from the quadratic formula, which states that the roots of the equation 
are
![\[x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\]](http://latex.artofproblemsolving.com/d/0/1/d01fd749d6550b117a645c357f01b3c9377e5756.png)
which, when read aloud, is "negativebplusorminus..."

which can be derived from inputting that equation into itself.
Notable Work

Welcome to the AoPSWiki! The AoPSWiki is a wiki (or a publicly editable online resource) project administered by the Art of Problem Solving for supporting educational content useful to avid math students. Unlike most online resources, the AoPSWiki is meant to be easily readable by even the least advanced student. Also, the AoPSWiki, being a wiki, can be edited by anyone! AoPSWiki runs on the MediaWiki software. |
