CalcSharp

CalcSharp is .Net application that evaluates mathematical expressions step by step.

It uses a different approach from a conventional calculator, which is more
natural to the way people calculate. When you calculate on a conventional
calculator, each time you enter a new number you lose sight of the previous
one. And if you make a mistake in the middle of a long expression, you have
to start all over. In CalcSharp, you can see all of what you are calculating,
and expressions can easily be edited.
