Comment (by ywwg):

 I tried the version linked above.  The fonts are nicely sized now and the
 input behaves as I'd expect.  It seems to work nicely, and at least for
 simple math it's fine.  I didn't check the results of more complex
 operations against a regular calculator so I can't vouch for the
 correctness of the higher math.

 I also think it should use × instead of * and ÷ instead of /.
