I'm not certain exactly what you are looking for here, but maybe this simple example will help. Copy and paste the entire expression into one cell of a notebook and evaluate. You could develop an annotated derivation this way by adding steps and reevaluating. Print["Starting equation"] radius == HoldForm[1 + 1] Print["Evaluate the rhs"] %% // ReleaseHold Print["Add x to both sides"] # + x & /@ %% Print["Square the result."] #^2 & /@ %% Print["Expand the right hand side."] MapAt[Expand, %%, 2] David Park djmpark at comcast.net http://home.comcast.net/~djmpark/ From: Sam Takoy [mailto:sam.takoy at yahoo.com] Hi, When Mathematica prints an expression not terminated by a semicolon, I find it hard to match up the output with what I was trying output when a block of commands has many commands not terminated by a semicolon. Is there a way to get Mathematica to output the LHS so when I have R=1+1 it outputs R = 2 or something like that. Thanks!
