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]

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!
