Are you doing this as an exercise, a learning experience, or to get usable tool?

If the latter, have you tried the bc package? It does nearly what you are trying to do.
I entered "5 * 10", it returned 50, I entered "quit" to get back to my shell prompt:
Code:
bc -q
5 * 10
50
quit

Multiplication is written using the multiplication sign "×" between the terms ...

-- Multiplication - Wikipedia, the free encyclopedia
This means more work for you in the script -- test $2 for an "x", substitute a "*" and continue with (( ... )), bc, etc. If one is trying to make a client happy, then there is often more such work required from the provider ... cheers, drl
