moderated Re: Windows 10 calculator refuse to display the answer
I realize this does not answer your question, but it does present another option should you prefer it. I am not a huge fan of the Win10 calculator app, preferring the more "old-school" calculator. I archived the installer for Microsoft Calculator Plus on my Google Drive quite a while back.
It's another option, and it neither removes nor replaces the Win10 Calculator App when installed. It's what I keep on my taskbar as the calculator of choice.

To think is to differ.
