<>排版
* 行内公式：用\ 或者 $ 包裹公式
如：$ \ x+y=1 $
* 独立公式：用 $ 包裹公式。
如：
( x + y ) \sqrt(x+y) ( x+y)
特殊字符：# $ % & ~ _ ^ \ { }有特殊意义，如果需要使用需要在前面添加英文句号.来经行转义
<>给公式添加轮廓
\boxed命令给公式加一个方框
1. x + y = 1 \boxed {x+y=1} x+y=1
2. x + y = 1 \boxed x+y=1 x+y=1
3. x + y = 1 x+ \boxed y=1 x+y=1
<>希腊字母
<>上、下标和根号、分数
用^来表示上标， 用_来表示下标，根号用\sqrt表示，上下标如果多余一个字符或符号，需要用{}括起来。\quad表示添加空格，分数用\frac表示
<>运算符
“+ - * / = ”直接输入，可以通过\limits和\nolimits命令显示制动是否压缩，特殊运算则用以下特殊命令。
\pm; \times; \div; \cdot; \cap; \cup; \geq; \leq; \neq; \approx; \equiv
;\sum; \prod; \lim; \int;
± × ÷ ⋅ ∩ ∪ ≥ ≤ ≠ ≈ ≡ ∑ ∏ lim ∫
\pm\; \times\; \div\; \cdot\; \cap\; \cup\; \geq\; \leq\; \neq\; \approx\;
\equiv\sum\; \prod\; \lim\; \int\;±×÷⋅∩∪≥≤=≈≡∑∏lim∫
特殊：x\to0
x → 0 x\to0 x→0
