SpeQ -- Small Powerful Math Program (Discovery)
Windows Calculator is a joke -- who wants to use the on-screen version of a $5 dollar calculator. Most replacements are far more powerful but kind the "lots of buttons" calculator interface. SpeQ break the calculator-look mode. It looks more like a text editor that lets you enter calculations -- and even say your work. SpeQ can be used by anyone for simple math problems but it is powerful enough to be useful to engineers and scientists.
