希腊字母
斜体小写希腊字母一般用于在方程中显示变量.

黑板粗体
黑板粗体（Blackboard bold）一般用于表示数学和物理学中的向量或集合的符号. 备注：
 * 语法:
 * 效果:$$\mathbb{ABCDEFGHIJKLMNOPQRSTUVWXYZ}$$
 * 1) $$\{ \,$$花括号$$\} \,$$中只有使用大写拉丁字母才能正常显示，使用小写字母或数字会得到其他符号.

正粗体

 * 语法:
 * 效果:$$\mathbf{0 \ 1 \ 2 \ 3 \ 4 \ 5 \ 6 \ 7 \ 8 \ 9}$$
 * $$\mathbf{a \ b \ c \ d \ e \ f \ g \ h \ i \ j \ k \ l \ m \ n \ o \ p \ q \ r \ s \ t \ u \ v \ w \ x \ y \ z}$$
 * $$\mathbf{A \ B \ C \ D \ E \ F \ G \ H \ I \ J \ K \ L \ M \ N \ O \ P \ Q \ R \ S \ T \ U \ V \ W \ X \ Y \ Z}$$


 * 备注:花括号{}内只能使用拉丁字母和数字，不能使用希腊字母如\alpha等.

斜粗体

 * 语法:
 * 效果:$$\boldsymbol{0 \ 1 \ 2 \ 3 \ 4 \ 5 \ 6 \ 7 \ 8 \ 9}$$
 * $$\boldsymbol{a \ b \ c \ d \ e \ f \ g \ h \ i \ j \ k \ l \ m \ n \ o \ p \ q \ r \ s \ t \ u \ v \ w \ x \ y \ z}$$
 * $$\boldsymbol{A \ B \ C \ D \ E \ F \ G \ H \ I \ J \ K \ L \ M \ N \ O \ P \ Q \ R \ S \ T \ U \ V \ W \ X \ Y \ Z}$$
 * $$\boldsymbol{\alpha \ \beta \  \gamma \  \delta \  \epsilon \  \zeta \  \eta \  \theta \  \iota \  \kappa \  \lambda \  \mu \  \nu \  \xi \  o \  \pi \  \rho \  \sigma \  \tau \  \upsilon \  \phi \  \chi \  \psi \  \omega}$$


 * 备注:使用 可以加粗所有合法的符号.

斜体数字

 * 语法:
 * 效果:$$\mathit{0123456789}\!$$

罗马体

 * 语法:
 * 效果:$$\mathrm{0123456789}\ $$
 * $$\mathrm{ABCDEFGHIJKLMNOPQRSTUVWXYZ}\ $$
 * $$\mathrm{abcdefghijklmnopqrstuvwxyz}\ $$


 * 备注:罗马体可以使用数字和拉丁字母.

哥特体

 * 语法:
 * 效果:$$ \mathfrak{0 \ 1 \ 2 \ 3 \ 4 \ 5 \ 6 \ 7 \ 8 \ 9}$$
 * $$ \mathfrak{a \ b \ c \ d \ e \ f \ g \ h \ i \ j \ k \ l \ m \ n \ o \ p \ q \ r \ s \ t \ u \ v \ w \ x \ y \ z}$$
 * $$ \mathfrak{A \ B \ C \ D \ E \ F \ G \ H \ I \ J \ K \ L \ M \ N \ O \ P \ Q \ R \ S \ T \ U \ V \ W \ X \ Y \ Z}$$


 * 备注:哥特体可以使用数字和拉丁字母.

手写体

 * 语法:
 * 效果:$$\mathcal{ABCDEFGHIJKLMNOPSTUVWXYZ}$$
 * 备注:手写体仅对大写拉丁字母有效.

希伯来字母

 * 语法:
 * 效果:$$\aleph\beth\gimel\daleth$$

括号
您可以使用  和   来显示不同的括号： 备注：
 * 可以使用  控制括号的大小，比如代码

显示︰
 * $$\Bigg ( \bigg [ \Big \{ \big \langle \left | \| x \| \right | \big \rangle \Big \} \bigg ] \Bigg )$$

空格
注意TeX能够自动处理大多数的空格，但是您有时候需要自己来控制.

顏色
＊註︰輸入時第一個字母必需以大寫輸入，如.
 * 語法:
 * 字體顏色︰
 * 背景顏色︰
 * 支援色調表:


 * 例子:
 * $$ {\color{Blue}x^2}+{\color{Brown}2x} - {\color{OliveGreen}1}$$
 * $$ {\color{Blue}x^2}+{\color{Brown}2x} - {\color{OliveGreen}1}$$



小型數學公式
當要把分數等公式放進文字中的時候，我們需要使用小型的數學公式. 此功能並不常用. ——应当推广此用法！
 * 10 的 $$f(x)=5+\frac{1}{5}$$ 是 2. 　並不好看. 
 * 10 的 $$ 是 2. 　✅好看些了. 

可以使用 \begin{smallmatrix}...\end{smallmatrix}

或直接使用Smallmath模板. $$

強制使用PNG
假設我們現在需要一個PNG圖的數學公式.

若輸入  的話：
 * $$2x=1$$
 * ↑ 這並不是我們想要的.

若你需要強制輸出一個PNG圖的數學公式的話，你可於公式的最後加上 （小空格，但於公式的最後是不會顯示出來）.
 * 輸入 的話：
 * $$2x=1 \,$$
 * ↑ 以PNG圖輸出.

你也可以使用 ，這個亦能強制使用PNG圖像.
