Calculator: Add more assignment operators (+=, -=, *=, /=...)

The calculator has the “=” operator, the “+” and “-” operators, etc.

It would be nice to also have the “+=”, “-=”, etc. operators.

Note on how I use the calculator: I write down my recurring expenditure (monthly and annually) so that I can see how much I spend per month/per year.

Welcome.

The ability to execute JavaScript code is superb, but I prefer something like “calculator” with live rendering, and directly integrated into the tool.

Nevertheless, thanks for the idea.
