Add short reference to Mathjax Latex Commands [duplicate]

Question

Some new users don't know and not familiar with the $\LaTeX$ syntax. It is perfectly normal but it would be better if we refer them a nice reference that explains the basics.

Also, I suggest that we can add a link to this question in the help page.

Answer 1

The math mode can be used for inline in $...$ as $x^2+x$ and for centered new line $$....$$ as; $$x^2+x$$

MathJax supports essentially the commands native to $\LaTeX$ as well as those defined by amsmath and amssymb (with some exceptions in both directions). For a complete list, see the MathJax reference.

Here some helpful one;

• subscripts x_2 $x_2$, if more than one char use braces x_{12} $x_{12}$
• supercripts x^2 $x^2$, if more than one char use braces x^{12} $x^{12}$
• \operatorname{name} for names of the operators with non-italic and spacesing
• \mathbb{Z} for groups, fields as \mathbb{Z_p} $\mathbb{Z_p}$, $\mathbb{F_q}$
• \mathcal{O} for calliographic letters, \mathcal{O}, $\mathcal{O}(n \log n)$
• align to align the equations; as \begin{align*} A & = B \\ & = C \end{align*} aligned with = $$$$ \begin{align*} A & = B \\ & = C \end{align*} $$$$
• use \dots for ...
