Whitespace

As a general rule it's better to put space between pieces of a formula if there is the slightest possibility of ambiguity. (It's more work for a PPer to have to go through every formula adding whitespace to improve legibility than it is for the PPer to check that no formula has been rewrapped at an inopportune location.) So your example

e^(a + bi) = e^a(cosb + isinb)

would be much easier to read with some extra whitespace:

e^a(cos b + i sin b)

Also, in this example the added parentheses seem to be inconsistent with general practice for sub/superscripts: braces would be preferable

e^{a + bi}

Names for symbols

It's a much better idea to name a symbol for its function than for its alphabetic heritage. Hence the summation symbol Σ would be better rendered as [Sum] than as [Sigma]. Also, the limits of summation (and of integration) are conventionally read from bottom to top, so your example read out loud would be

e to the z equals the sum from n=0 to infinity of z to the n over n factorial

In my view a better rendering of the sum would be {n=0}[Sum][infinity], or perhaps the LaTeXesque {Sum]_{n=0}^[infinity], here using braces to avoid introduction of parentheses not present in the original and to be consistent with the standard grouping used with sub/superscripts. When a symbol does not have a standard abbreviation, it's preferable to use the full name ("infinity") rather than contrive a contraction ("infin" in your example).
