Multiplication or separate expressions when evaluating lines in a cell?
When I evaluate an expression like the following, Mathematica multiplies the three results together to produce one numerical answer -- 7.55312899932103487`*^20 in this case. Note: the following three lines are all in _one_ cell. (* 1st word *) N[(2*Pi/1*^-6)*1.40] (* 2nd word *) N[(2*Pi/1*^-6)*1.45] (* 3rd word *) N[(2*Pi/1*^-6)*1.50] When I place each comment after its expression like this N[(2*Pi/1*^-6)*1.40] (* 1st word *) N[(2*Pi/1*^-6)*1.45] (* 2nd word *) N[(2*Pi/1*^-6)*1.50] (* 3rd word *) then evaluation of the cell returns the three results I expect. Of course (?), if I place each expression in its own cell, then each expression is evaluated correctly. I was surprised when the three (what I thought were separate) lines were evaluated as a product because, when I evaluated them in a different notebook during a previous session, they were evaluated normally -- as three separate expressions. I am running ver 3.0 for Win 95. I have been changing the Prining Style Environment in my notebooks some (in a feeble attempt to see how my notebook will printout before actually printing it). There is nothing unusual in the cells before the cell I'm trying to evaluate (properly?) -- just some text cells and an input cell with some function definitions.
