上標、下標

上標用a^b就是$a^b$，但是如果上標的字元不只一個字，就必須用{}包起來，例如：a^{b+c}才會是$a^{b+c}$，如果直接寫 a^b+c會變成$a^b+c$。下標則是X_i，跟上標一樣，如果下標字元不只一個字，也要用{}包起來，例如：X_{i+1}就是 $Xi+1$。

除法

\frac{a-b}{c} → \frac{a-b}{c}

開根號

\sqrt{a+b+c} → \sqrt{a+b+c}

加總

\sum_{n=1}^{\infty} 2^{-n} = 1 → \sum_{n=1}^{\infty} 2^{-n} = 1

括號的大小

((x))可以產生$((x))$，但如果要讓外圍的括號放大，就必須把外圍的括號加上\big才行。例如：\big((x)\big)表示\big((x)\big) 由小到大可用的分別是\big、\Big、\bigg、\Bigg 例如： \Bigg(\bigg(\Big(\big((a+b)+c\big)+d\Big)+e\bigg)+f\Bigg)表示\Bigg(\bigg(\Big(\big((a+b)+c\big)+d\Big)+e\bigg)+f\Bigg)

矩陣

用\begin{bmatrix}與\end{bmatrix}包起來，其中的行列用\\來換行。
\begin{bmatrix}a & b & c\\d & e & f\end{bmatrix}表示$\begin{bmatrix}a & b & c\\d & e & f\end{bmatrix}$
或用pmatrix來產生括弧的矩陣： \begin{pmatrix}a & b & c\\d & e & f\end{pmatrix}表示\\begin{pmatrix}a & b & c\\\\d & e & f\\end{pmatrix}

對齊

使用\begin{align}與\end{align}，其中上下行需要對齊的字元後面加上&。 \begin{align}y=a&+b+c+\\d&+e+f\end{align}表示

\[ \begin{align}y=a&+b+c+\\d&+e+f\end{align} \]

由於是a&與d&，可以看到a與d對齊了。
