Talk:Commutative matrix multiplication

Hi User:Michael_Hardy, unfortunately I have reverted all your changes, because I don't see an easy way to revert individual changes. I prefer a consistent &lt;math&gt; style because I think that this is closer to the semantics. I do not want to write something in italics, but I want to say "this is a formula". Also see MOS:MATH with respect to changing other peoples style. From what I have learned in complex function theory, logarithm is a single-valued function, but there are several definitions depending on the domain and the $$2\cdot\pi\cdot i$$ offset. After encountering several problems with distinction of function (or operator) application and multiplication I'm used to explicitly write the multiplication dot.
