Kinda tries to do chain rule and fails, also bad/

Simplifies +,-,* properly but doesn't yet handle / properly. Can try to
do the chain rule but this will take some work, may need to just be
restarted all together.  Also, having a hard time keeping track of the
coefficients throughout the chain rule application, this should be an
easy fix though.  Just needs more time, I think we are on the right
track.
