Well, any of Expand, Simplify, Together, Apart ... will do (at least with the actual expression, you posted). However, why did you post the expression in TeX syntax? Wouldn't it be easier to type 4(a/4+b/4 c)? /Sigmund On Nov 3, 11:26 am, AES <sieg... at stanford.edu> wrote: > I have a simple, totally algebraic symbolic calculation that displays > its output in the form (rewritten here using TeX notation) > > 4 ( {a \over 4 } + { b \over 4 c } ) > > where a, b and c are fairly simple products of purely algebraic > quantities; \over is the TeX notation for a display fraction; and the > curly brackets are just for TeX purposes and are not there in the actual > output. > > Is there any Assumption for Simplify, or any other _simple_ way, to get > rid of those (utterly!!!) superfluous 4's? > > [I suppose the real question is, why doesn't M cancel 'em the hell out > in the first place?!?!]
