Is there a way to start Calc, taking the region as input and replacing it with the value?

Is there a way to start Calc, taking the region as input and replacing it with the value?

[Marcin Borkowski]

Well, the subject is basically what I want.  I'd like to be able to
type, e.g., "2+3", mark it as a region, and press *something* only to
get it *replaced* by "5".

C-u C-x * g C-x * y q is pretty close, but not the same (and way too
long to be comfortable).

If there's no such thing, I could probably write it in Elisp myself,
but why reinvent the wheel?

Best,

Exactly for this purpose I use macro-math:

Thanks a lot, seems to be exactly what I meant (though rounding would
be less useful for me)!  Meanwhile, I recalled about the embedded mode,
which does a very similar thing.
