Found a big problem with order of operations.

I believe this is because I'm using right tail recursion, but I'm not really
sure how I could change it for this program.

order of operations is being observed perfectly, but then operations are being
performed from right to left, not left to right.  I think I may be reducing
too frequently, honestly.
