BestCalc

Have you ever wondered whether or not you already touched the operator and now have to enter the next number, or maybe if you touch the next number the previous result will vanish, and you will have to start over again? Here is, at last, a calculator that shows you what it does. It even takes away the mystery out of the memory thing, and on top of that, it allows useful conversion between English and metric units instantly.

Requirements:

Windows 98/Me/2000/XP/2003 Server/Vista, Microsoft .NET Framework
