Follows the same general format (240 * 100 calculations) as @PutneyCat's entry: https://scratch.mit.edu/projects/186608592/ See https://scratch.mit.edu/projects/187024496/ for more information - this calculator does NOT handle algebra well and fails on anything more complex than y=(.. something something x..). Support for the x variable is hacked in! On my computer this runs for a total time of 49.5 seconds. Not near as fast as @PutneyCat's (linked above), which runs for 30.5 seconds here; oh well! Mine is better at solving most of the equations. I haven't tested, but it should be able to do most of the bonus equations. Unfortunately, that only gets me (at most) 0.3s off of my total score.. which is nearly 20s greater than PutneyCat's :)
