You can post complex math equations in a simple and fast way using Markdown and KaTex. No need to take screenshots to write about math, use [KaTex](https://khan.github.io/KaTeX/) syntax to display formulas, equations, symbols, and functions unline and in block as described bellow. It will serve you well for mathematical blogs and notes taking.

### Inline math
To add a math element in text, surround it by double dollar marks `$$\sqrt{x}$$`, and it will automatically convert it to look like this: $$\sqrt{x}$$.

### Block math
To add a math element in block, use either ```math``` or ```katex``` command code between block code fences ` ``` `, like this:

    ```katex
    \cfrac{a}{1 + \cfrac{1}{b}}
    ```

```katex
\cfrac{a}{1 + \cfrac{1}{b}}
```

        <content type="html"><![CDATA[##Emphasis

Standard Markdown allows you to do some basic formatting, for example making text *italic* or **bold**. Bold and italic is about as much formatting allowed in standard Markdown. Various Markdown implementaions over time have come up with different extensions. P4 implements a number of them. 

By surrounding text with specific punctuation marks, you can do the following formatting. You can choose whichever style you prefer, the only rule being is that the same character must be used to open and close an emphasis span.

Use `*` or `_` for *italic text*: 

    *italic text* or _italic text_

Use `**` or  `__` for **bold text**:

    **italic text** or __italic text__
    
Use `==`to ==highlight==:

    ==highlight==	

Use `~~` to ~~strikethrough~~:

    ~~strikethrough~~

Use `++` to ++underline++:

    ++underline++
    
Use `^` for A^superscript^ or A~subscript~:

    ^superscript^ or ~subscript~

        <content type="html"><![CDATA[##Lists

Markdown supports both ordered (numbers) and unordered (bullets) lists.

- For **ordered list** use numbers followed by period. You can use sequential numbers or keep all numbers as `1.`:


    1.
    2.
    
1. 
2. 


- For **unordered list** you can use either `-`, `*`, or `+`  interchangably to create unordered bullet list:



    + Item 1
    * Item 2
    - Item 3
     - Sub-lists are made with extra space
        - Third level


- Item 1
+ Item 2
* Item 3
  - Sub-lists are made with extra spaces
     - Third level

You can also mix the two and use a combination of ordered list and underordered sublist.

Markdown supports inline and reference style images. To add an inline style image, use the following notation `![...](...)`, whereby you insert a link to an image in round brackets `(Link to Image)`:

    ![](http://i.imgur.com/MB6vVNv.png)

![](http://i.imgur.com/MB6vVNv.png)

You might have noticed that the image notation is similar to the link notation with the only difference being an exclamation mark `!` that goes before the first set of square brackets.]]></content>

You can insert a link into your text in Markdown using `[...](...)`, whereby you type the name of the link in square brackets `[P4]`, followed by the link itself in round brackets `(https://onp4.com)` like that [P4](https://onp4.com):

    [P4](https://onp4.com)
  
You can also type a link as is `https://...`, but this is not recommended, as it is regarded as text.

Inline code is helpful when writing about programming or showing a source code.  

For simple **mark-up**, put a word between single back-ticks:

    `code block`
    
 `code block`

For more **technical text**, use double back-ticks specifying the language, for example:

- JS

        ``js console.log(123)``
        
        ``js console.log(123)``


- HTML

        ``html <div class="text"     style="border:1px solid red">Hello world</div>``

    ``html <div class="text" style="border:1px solid red">Hello world</div>``



- Keystrokes

        ``key Enter``

 ``key Enter``


- Path 

        ``path C:\Program Files\virus.exe``

 ``path C:\Program Files\virus.exe``]]></content>

        <content type="html"><![CDATA[##Headings
Headings are usually set using a hash before a title. The number of hashes determine the depth of the heading. Hash heading depths range from 1-6:

    H1: # Heading 1
    H2: ## Heading 2
    H3: ### Heading 3
    H4: #### Heading 4
    H5: ##### Heading 5
    H6: ###### Heading 6

# H1
## H2
### H3
#### H4
##### H5
###### H6


Alternatively, for H1 you can use `----` instead of `#` underneath the heading, and for H2 `====` instead of `##`:

    H1: Heading 1
    -------------
    H2: Heading 2
    =============


You can also use inline formatting and links inside the headings:

    #*Heading in italic*
    #Link in the heading to [P4](https://onp4.com)]]></content>

Markdown is a simple formatting tool that helps turn plain text into a pretty document, --- be it a post, a blog, a paper, a book or just a couple of notes. 

It enables faster creating and editing of posts. You can mark up your text in nearly any way you like. It is widely used, easy to pick up and makes writing much more productive.

Markdown gives you a nice durable way to create readable text that you will be able to read and edit any time. It eliminates dependency on a single software app and lets you create, publish and share with confidence.

When presenting content in Markdown, the input looks as nice as the output.
