calculate answer units based on calculation units
... like the programming language Frink (http://futureboy.us/frinkdocs/) does.
Examples of Frink calculation with units, on their web-based interface:

http://futureboy.us/fsp/frink.fsp?fromVal=unit_price+%3D+%2875+cents%29+%2F+%281.74+oz%29+-%3E+dollars+%2F+lb&toVal=&lookup=
Some sample calculations and what I want them to look like:

Great feedback. I need to do a lot of work on the Instacalc parser, but having units tag the numbers is one of them. Thanks for the thoughtful example!
