I just learned of this calculator:
http://qamacalculator.com/
It works like any other, but it won't give you the answer until you tell
it a "reasonable" estimate of the correct value!
The tricky part, apparently, was defining "reasonable" -- single digit
mulitplications require the exact answer, but other things are more
accepting.
Also, it's only $20! I bought one.
It would be neat to have a front-end for the cell server that does
something like this...

That is an interesting idea. It would be neat to have a front-end like

this. You could take it even farther and make someone draw an estimate
of a graph, etc.
Thanks,

Another idea is an RPN front-end, which given the syntatical unambiguity

of RPN ought to be easy...and fun to give to students and see them wrap
their heads around it.
