M-x calc

this does take some time to get used to but it is a very god rpn
calculator. It does algebra and other things.

M-x calc

in calc mode you can enter alibraic mode by using the ' character.

1 <RET>
'
pi <RET>
+ 
= <RET>

calc-mode is hard to use. there is excellent documentation for it in the
emacs manual.
