This calculator allows natural entry of expressions (i.e. 17-(9*8) - 7 + 34.23). Then it goes beyond just giving you a result, the "steps" box, shows you how it solved the expression step by step. Results are given simultaneously in dec/hex/oct/bin. Great for students and home use. It takes the mystery out of solving complex expressions.
Version 3.3 improves installer and user interface.
