From Armin Richter:
Calculator Pro is a scientific windows calculator that can solve large mathematical terms. Therefore Calculator Pro supports a lot of mathematical calculations i.e. complex numbers, matrices, as well as several unit conversions. Furthermore, Calculator Pro can be used for plotting simple curves, 2-dimensional diagrams, simple animations, etc.. Basically, the Calculator Pro is based on a multi-line text box, which makes the handling very easy and transparent. Also, that text box allows for keeping all carried out calculations present. The Calculator Pro offers a lot of more features, so just test them!
This program does scientific calculations using all the standard operators similar to a TI-83. The program is free. It installs in both English and Dutch and the internet update function Works!!! A big plus! This program is nice and I highly recommend it.
Cons
I had to figure out how to set the text size it was set at 635 LOL. Click the tool icon and then font size and you can change it.
