I'm a mathematician working in algebra. I've been using TeX since 1987, but couldn't write my Ph.D. thesis with it. Sob!

I teach LaTeX at my university, besides the mathematics courses. I'm the author of some LaTeX packages and even of one Plain TeX package. At my site it's possible to download my book on LaTeX programming (in Italian, sorry).

Here's my motto for TeX.SX:

Pronto prontissimo son come il fulmine: sono il factotum della città. (From "Il barbiere di Siviglia", music by Gioachino Rossini, libretto by Cesare Sterbini.)

comment Need for loading of expl3 code?
\fp_eval:n is very powerful and perhaps there will be a user interface to it, which there isn't at present.

comment Conditionally Remove Brackets
There is also \IfValueT that's perhaps more intuitive than \IfNoValueF, in this case.

comment Are there more to applications of \iftrue and \iffalse?
@Jesse \iftrue and \iffalse can sometimes get handy, but in general the \newif abstraction is better.

\expandafter\let\expandafter\calculate\csname fp_eval:n\endcsname will do the same; what's bothering you?

Beware of using html.sty: it's a rather old and unmaintained package.

comment Are there more to applications of \iftrue and \iffalse?
After \newif\ifbigger, \biggertrue and \biggerfalse are just \let\ifbigger=\iftrue and \let\ifbigger=\iffalse, so the third code is exactly the same as the first one.

comment Roman pagenumbering + \usepackage[greek]{babel}
This question appears to be off-topic because it is about a bug already solved in a new version of the relevant package.

comment Line break in large formula and error message in align?
You can't use \left in one line and \right in another; by the way, they aren't necessary in this context.

Using \DeclareMathOperator for “Var” and “Cov” should be recommended

comment Is any downside in using align instead of \[…\]?
Welcome to TeX.SX! Yes, there are downsides; never use align for one liners.
