Your use cases are valid and should be respected and supported. What I was saying is, there are other people who prefer keyboard for efficiency, and they don't need keypad. Make it optional and hideable so that all users are happy. It's very simple change in terms of code diff, but it seems very hard in terms of design choice since even Microsoft doesn't get it.

Making the keypad optional adds user confusion. It might be a worthwhile tradeoff if doing so is necessary to save screen space, but if the keypad is actually accounting for such a significant portion of your screen real estate, I'd love to see your monitor.

As I hinted in my previous comment, power users of Windows, don't use apps bundled with Windows! :D

You can download a calculator that is designed to your preferences. I actually wrote a calculator in Autohotkey that was a keylogger constantly checking if last typed characters can be interpreted as a mathematical expression - if so, the expression was evaluated and displayed as a tooltip, and pressing a shortcut could be pressed to paste an equal sign and that evaluated value. Never finished it though, demotivated by how hard it was to port to other OSes.
