It wouldn't surprise me - I'll often do the same with Python on non-Windows systems rather than bothering with the native calculator; I'm not even sure if Linux has one (or if it's the same across distros), and Python is ubiquitous, fast, and has familiar syntax.

Same here, I don't have an actual calculator program so python is generally the quickest way for me.
