xcalc
xcalc is a scientific calculator for the X Window System.
Installation
Install the xorg-xcalc package.
Configuration
There are several options you can set in your X resources files to make xcalc look much better than the default black text on white background. The position, label, function and colour can be individually changed for each button. See xcalc(1) § CUSTOMIZATION for more information.
Theming
xcalc has a built in theme emulating the looks of a Texas Instruments TI-30. See xcalc(1) § COLORS on how to enable it.
If you just want some nicer looking colours, you can try out this theme.

Change the division label
You can change the division symbol to a forward slash if you prefer.
