Well, it does matter since you want some kind of MMa script, I and i behaves differently. Is this waht you are after?: expr = a + I*b + d - I*e + r; Row[(ComplexExpand[{1, I} Through[{Re, Im}[expr]]]), "+"] or more safe but with additional brackets HoldForm[+##] & @@ (ComplexExpand[{1, I} Through[{Re, Im}[expr]]])

So you need I and to use == not = first of all.

Is i meant to be an imaginary unit?
