* use tag: start <nowiki><math></nowiki>, and the end close it <nowiki></math></nowiki>. Like: <math>E = mc^2</math>

* <math>\alpha</math>

* Superscript <math>a^x</math>

* Subscript <math>b_1</math>

* Grouping <math>a^{x+y}, i_{1...n}</math>

* Combining sub & super without and with horizontal separation <math>a_2^3</math> or <math>{a_2}^3</math>

* Super super <math>a^{b^x}</math>

* Sum <math>\sum_{k=1}^N k^2</math>

* Sum (force \textstyle) <math>\textstyle \sum_{k=1}^N k^2</math>

* Product <math>\prod_{i=1}^N x_i</math>

* Product (force \textstyle) <math>\textstyle \prod_{i=1}^N x_i</math>

* Limit <math>\lim_{n \to \infty}x_n</math>

* Limit (force \textstyle) <math>\textstyle \lim_{n \to \infty}x_n</math>

* Fractions <math>\frac{a}{b}=c</math> or use 'over' <math>{a \over b}=c</math>

* Small fractions <math>\tfrac{x}{y} = z</math>

* Matrices <math>\begin{matrix}
x & y \\
z & v
\end{matrix}
</math>
or
<math>
\begin{vmatrix}
x & y \\
z & v
\end{vmatrix}
</math>
or
<math>
\begin{pmatrix}
x & y \\
z & v
\end{pmatrix}
</math>
or
<math>
\begin{bmatrix}
x & y \\
z & v
\end{bmatrix}
</math>
or
<math>
\begin{Bmatrix}
x & y \\
z & v
\end{Bmatrix}
</math>
or
<math>
\begin{bmatrix}
0 & \cdots & 0 \\
\vdots & \ddots & \vdots \\
0 & \cdots & 0
\end{bmatrix}
</math>

*Parenthesizing big expressions, brackets, bars <math>\left ( \frac{1}{2} \right )</math>

* Simultaneous equations <math>
\begin{cases}
3x + 5y + z \\
7x - 2y + 4z \\
-6x + 3y + 2z
\end{cases}
</math>

* Multiline equations <math>
\begin{align}
f(x) & = (a+b)^2 \\
& = a^2+2ab+b^2 \\
\end{align}
</math>

* Multiline equations (more) <math>
\begin{array}{lcr}
z & = & a \\
f(x,y,z) & = & x + y + z
\end{array}
</math>
