\[+ - = ! / ( ) [ ] < > | ' : * \ \]数学表达式\pm \mp
\sqrt{\frac{a}{b}}
\sqrt [ a ] {b} \quad
\int_0^\infty \mathrm{e}^{-x}\,\mathrm{d}x
\int\limits_a^b \iint\limits_a^b
\sum_{i=1}^{10} t_i 或者 \displaystyle\sum_{i=1}^{10} t_i
\sqrt[n]{1+x+x^2+x^3+\dots+x^n}
k_{n+1} = n^2 + k_n^2 - k_{n-1}
f(n) = n^5 + 4n^2 + 2 |_{n=17}
\frac { n! }{ k!(nk)! } = \binom { n }{ k }
\frac { \frac { 1 } { x } + \frac { 1 } { y }} { y-z }
^3/_7
\begin{equation}
x = a_0 + \cfrac{1}{a_1
+ \cfrac{1}{a_2
+ \cfrac{1}{a_3 + \cfrac{1}{a_4} } } }
\end{equation}
\begin{equation}
\frac{
\begin{array}[b]{r}
\left( x_1 x_2 \right)\\
\times \left( x'_1 x'_2 \right)
\end{array}
}{
\left( y_1y_2y_3y_4 \right)
}
\end{equation}
基本矩阵
\begin{matrix}
a & b & c \\
d & e & f \\
g & h & i
\end{matrix}
要指定表格中列的对齐方式，请使用带*的版本
\begin{matrix}
-1 & 3 \\
2 & -4
\end{matrix}
=
\begin{matrix*}[r]
-1 & 3 \\
2 & -4
\end{matrix*}
通常使用水平、垂直和对角三组点（称为椭圆(ellipses)）来填充某些列和行。这些可以分别使用\cdots,\vdots和指定\ddots：
A_{m,n} =
\begin{pmatrix}
a_{1,1} & a_{1,2} & \cdots & a_{1,n} \\
a_{2,1} & a_{2,2} & \cdots & a_{2,n} \\
\vdots & \vdots & \ddots & \vdots \\
a_{m,1} & a_{m,2} & \cdots & a_{m,n}
\end{pmatrix}
数组环境
\begin{array}{c|c}
1 & 2 \\
\hline
3 & 4
\end{array}
M = \begin{bmatrix}
\frac{5}{6} & \frac{1}{6} & 0 \\[0.3em]
\frac{5}{6} & 0 & \frac{1}{6} \\[0.3em]
0 & \frac{5}{6} & \frac{1}{6}
\end{bmatrix}
运算符是一个用单词表示的函数
如三角函数（sin, cos, tan），对数和/指数（log, exp），极限（lim），以及迹和行列式（tr, det）
\[\arccos \cos \csc \exp \ker \limsup \min \\ \arcsin \cosh \deg \gcd \lg \ln \Pr\\ \arctan \cot \det \hom \lim \log \sec\\ \arg \coth \dim \inf \liminf \max \sin\\ \sinh \sup \tan \tanh \]\times

通用点（省略号），用于文本（公式之外）。它根据上下文自动管理自身前后的空格，这是一个更高级别的命令。
\ldots

输出与上一个类似，但没有自动空白管理；它在较低级别上工作。

\hdotsfor{n}
\(\hdotsfor{n}\)
要在矩阵中使用，它会创建一行跨越n列的点。
向方程添加文本
50 \text{ apples} \times 100 \text{ apples}
= \text{lots of apples}^2
在Colors中描述的包xcolor允许我们为方程添加颜色。
black, blue, brown, cyan, darkgray, gray, green, lightgray, lime, magenta, olive, orange, pink, purple, red, teal, violet, white, yellow.
k = {\color{red}x} \mathbin{\color{blue}-} 2
\color{red} C^2 \\
\color{yellow} A = \color{blue}{B} \mathbin{\color{red}{-}} \color{green}{C}
