X70%

The back button doesn't work. It just keeps popping the keyboard. Otherwise, great work.

P70%
by P####:

This app seems to be more along the lines of an APL interpreter not a generic big number calculator. When I tried doing some simple computations, 5*5+500*500, I got the result of ((5*5)+500)*500. This seems to be the correct result for APL but not for a regular calculator. This should be in the title of the app.

M70%
by M####:

Looks like fun. How much work would it be to run it from a terminal on os x, linux, or windows? Are there any plans for an output command?
