Is MathGroup becoming a LaTeX newsgroup? What is wrong with pasting ordinary Mathematica expressions in InputForm? In any case: 4 (a/4 + b/(4 c)) // FactorTerms a + b/c Or maybe: 4 (a/4 + b/(4 c)) // Together (b + a c)/c David Park djmpark at comcast.net http://home.comcast.net/~djmpark From: AES [mailto:siegman at stanford.edu] 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?!?!]
