Simple bc examples

I'm trying to figure out this bc calculator, but the man page doesn't seem to be very helpful to me.  Can I just get a quick and simple example of a short bc program for the SunOS 5.7 version?

Thanx.  I tried that earlier, but was being a dummy and didn't put the last line that prints everything out in there.  Duh.
