Basic Algebra

<mi> i stands for identifier

<mo> o stands for operator

<mn> n stands for number

<mrow> grouping

Subexpressions are grouped using the <mrow></mrow> tag.

<msup> Superscripts are defined using the <msup></msup> tag.
<msub> Subscripts are defined using the <msub></msub> tag.

Presentation Markup, but

Typographic decisions often carry mathematical meaning.

<mi> i stands for identifier

<mo> o stands for operator

<mn> n stands for number

This makes it hard to draw a clear line between presentation and content.
