Calcute: freeware calculatorCalcute: freeware calculatorUpgrade your regular Windows calculator: replace it with this unobtrusive scientific tape calculator. With sleek functionality, it improves upon traditional calculators. It can take very little space on your desktop if you want:
Calcute is more evolved than regular calculators. It is in fact an
expression evaluator. Unlike limited hand-held devices
where numbers disappear as soon as you enter the next one, Calcute lets
you enter a 
complete expression as if you
were using a regular text editor. You can see what you are doing so
you can easily make corrections. Type what you want to
calculate, press Enter to get the answer. The
calculator keypad can remain hidden or it can be
shown if you prefer to click buttons with the mouse instead of
typing.
You can stretch the display area to any size in order to retain and review past calculations, as if this were a paper tape calculator. But here you can also go back up the tape, edit past expressions and re-calculate them. You can even retain your work by saving everything to a file, to be restored later.
A number of interesting features are present in this little tool. Browse the site to learn about them, or just download the software and try it out. It's free! It's also clean: no spyware, no adware, nothing more than this handy calculator.
Enjoy!
