Eh? A lot do, going back to the HP9830 (and I think
the HP9820, but
it's been a few months since I used that machine). You can type in a
long expression and then evalulate it. You can also recall the
expression, change it and re-evalulate. Yes, these machines are almost
40 years old now...
I guess I've been brainwashed by too many cheap calculators. Looking
in my desk drawer, there are a bunch that I've used maybe once and
discarded. The latest is a solar-powered job with an all-but
invisible decimal point display, so to use it, you pretty much have
to keep track of the point mentally.
