Insert mathematical formula in MD document and mathematical formula in typora

Markdown It's a markup language , It can't be simpler ！ Just a few symbols , You can make concise and generous document notes .
therefore , How to be elegant MD Insert formula in document ？（ Below to Typora Insert LaTeX For example ）

First of all, we need to know what is LaTeX
Then learn how to MD Use it in .
 

LaTeX The mathematical formula

What is? LaTeX The mathematical formula , You can check the official website ：The fastest math typesetting library for the web.
In my submission , It's like Typora equally , Just use simple text symbols , You can make up complex mathematical formulas , Can be easily embedded in web pages or MD In the document .
 

Insert an introverted formula

The introverted formula follows the text directly , Don't occupy a single line . With ${\hat{f}}_i^k$ For example （ This is not a picture ）, Such a superscript Introverted mathematical formula , Just type... In the document ：

 $\hat f_i^k$

among $$ Identify the introverted formula , Just fill in the middle LaTeX that will do .（ Copy it into the document , Experience it. ）
 

Insert in line formula

In line formulas occupy a separate line , Take the following inline formula as an example ：
$$r_i^k=MLP\left(p_i\oplus p_i^k\oplus \left(p_i-p_i^k\right)\oplus \Vert p_i-p_i^k\Vert \right)$$
A formula block is required （ Similar code block ）：

$$
r_i^k = MLP\left( {
   {p_i} \oplus p_i^k \oplus \left( {
   {p_i} - p_i^k} \right) \oplus \left\| {
   {p_i} - p_i^k} \right\|} \right)
$$

among $$ Is a formula block , Fill in the middle LateX that will do .（ Copy it into the document , Experience it. ）
 

How to write quickly LaTeX The formula

See here , For how to insert a formula , You may already know . But how to write quickly LaTeX Well ？
Three options （ The last one is the most stupid ！）

1 Study LaTeX grammar （ Programmer in ）

In fact, writing LaTeX Understand as writing code , No problem at all , Any symbol in a mathematical formula , They all provide corresponding character expressions （ grammar ）.
How to learn grammar , You should be able to find a lot on the Internet ...
When you learn , Sure Read while writing ：

2 Convenient visual writing

LaTeX Formula editor

3 from MathType transformation （ Students join the party ！）

I'm sure you're right MathType I'm familiar with them , open preset — Cut and copy presets , Follow the screenshot below to set .

Then we write formulas normally , After that , Choose ,Ctrl+C Direct copy , stay MD Directly in the document Ctrl+V Paste , both LaTeX Format formula ！
Maybe after pasting , You also need to delete both ends of the formula \], about MD document \] It's redundant .
