# Typora math

• YAML Front matters now supports ending with three dots (…), based on the Yaml spec, “2.2. Structures”:

YAML uses three dashes (“—”) to separate directives from document content. This also serves to signal the start of a document if no directives are present. Three dots ( “…”) indicate the end of a document without starting a new one, for use in communication channels.

Three dot ending is also supported in Pandoc Markdown and Jekyll.

• Code Fences now is better GFM / CommonMark compatible. You can put extra </code> or , for example:

Previously, typora support this via inserting a zero-with whitespace, now it is no longer needed, and will be rendered as a red dot like what it is a source code mode. Please remove zero-with whitespace if they cause rendering issues in other markdown engines.

• Typora now follows GFM / CommonMark to parse as ordered list, for example:

• Use GFM compatible tables, please note that if you create table in hybrid editing mode, you will generate a well formatted and compatible table source code that follow changes and future changes will not affect your docs.

• Leading or trailing pipes are optional in table rows, and it does not make any differences.

• But please note that table will stop at block elements:

• The header row must match the delimiter row in the number of cells. If not, a table will not be recognized:

• Fix some other parsing bugs.

• One more thing: Typora v1.0 is coming! You could subscribe to our newsletters at https://typora.io/#subscribe to get notified. No spam, promised.

Typora supports rendering normal mathematics using Tex/LaTeX syntax. The rendering process is processed by MathJax.

### Math Block (Display Math)

Math blocks are LaTeX expressions wrapped by mark and line break, for example:

will be rendered as

\begin{align*} y = y(x,t) &= A e^{i\theta} \\ &= A (\cos \theta + i \sin \theta) \\ &= A (\cos(kx - \omega t) + i \sin(kx - \omega t)) \\ &= A\cos(kx - \omega t) + i A\sin(kx - \omega t) \\ &= A\cos \Big(\frac{2\pi}{\lambda}x - \frac{2\pi v}{\lambda} t \Big) + i A\sin \Big(\frac{2\pi}{\lambda}x - \frac{2\pi v}{\lambda} t \Big) \\ &= A\cos \frac{2\pi}{\lambda} (x - v t) + i A\sin \frac{2\pi}{\lambda} (x - v t) \end{align*}

In typora, you could just press and key to input a math block, in input mode, use Up/Down arrow key or / + key to finish editing, or just click the ✓ button, or somewhere else.

### Inline Math

First of all, please enable inline math feature from preferences panels -> Markdown section. Preferences panel can be opened From menu bar: -> , or use shortcut key — / + . This setting will be applied after Typora restarts.

Inline math use syntax like this , e.g: .

### TeX Commands available in Typora

You could find the all supported TeX commands in http://docs.mathjax.org/en/latest/input/tex/macros/index.html.

You could add new commands using or. For example:

### Chemistry Expressions

Typora has the built-in mhchem extension, which can be used to render Chemistry Expressions, you could use like this:

Which will be rendered as

For more details, please refer https://mhchem.github.io/MathJax-mhchem/.

### Cross Reference

Typora supports TeX-style reference syntax, for example:

### Auto Numbering

Typora supports auto-numbering math blocks. To turn on this feature, please open preferences panel, and enable “Auto Numbering Math Equations” under the “Markdown” section.

### Force Refresh

When Math rendering goes wrong, like output math too wild/narrow, or equation numbering becomes incorrect, you can trigger force refresh for all math from the → menu.

### Line Breaking

Starting from v0.11.0, Typora upgraded to MathJax v3, which does not support line break using or in MathJax v2, the behavior is same with LaTeX, unless you put them in a enviroment, for example:

So you could use as a workaround.

From v0.11.1, Typora provides a new option “Apply Line Break at \\” under → → . By enabling it, typora will auto wrap your math content with if your content contains or to achieve the same behavior as previous versions. But it may bring some unexpected issues, so if you met any math issues after enabled it, please try disable the option, and report to us, if it is the cause.

Use instead of enabling “Apply Line Break at \\” is recommended for adding line breaks in math.

## Using Snip with Typora

Equations can be inserted into Typora by either pasting or a PNG image into your Typora document. You can get both of these compatible formats when using Snip. We recommend using the LaTeX formats for adding math to a Typora document, but PNG images for tables.

To ensure that Snip is configured to work seamlessly with Typora, go to Settings (Preferences on Mac) > Formatting and select:

• delimiters for inline math
• delimiters for block mode math

Then go to Settings (Preferences on Mac) > Image Export and choose the Typora preset.

Make sure Typora is configured to work with LaTeX by going to Preferences > Markdown and enable inline math:

### Block mode math in Typora

To insert a block mode equation into Typora, follow these simple steps:

1. Display the equation want you to insert into your document on your screen.

2. Click the screenshot button on the Snip app or enter the keyboard shortcut /.

3. Click and drag the crop box around your desired equation, release to Snip.

4. Check your Snip result, then click the block mode math LaTeX format row ( delimiters) to copy to your clipboard.

5. Click into your Typora document where you would like to insert your equation and enter the shortcut / to paste.

6. Click away from the equation editing box to hide the LaTeX source code.

Here is a short video showing all the steps together:

### Inline math in Typora

To insert inline math into Typora, follow these steps:

1. Display the equation you want to insert into your document on your screen.

2. Click the screenshot button on the Snip app or enter the keyboard shortcut /.

3. Click and drag the crop box around your desired equation, release to Snip.

4. Check your Snip result, then click the inline math LaTeX format row ( delimiters) to copy to your clipboard.

5. Now click into your Typora document where you would like to insert your equation and enter the shortcut / to paste. You will see a preview of the equation below the code.

6. Type a space or to hide the LaTeX source code in your document.

Here is a short video showing all the steps together:

### Images in Typora

For non-math STEM content like tables, we recommend using the PNG output format instead of LaTeX (since Typora does not support any text-mode LaTeX features like the environment).

Snip has an image export setting optimized for Typora that will copy a high resolution (600 DPI) PNG to your clipboard which can then be resized once it’s been pasted into your Typora document.

Here are the steps for using PNGs from Snip in Typora with a table example:

1. Display the image of the table you want to to insert into your document on your screen.
2. Click the screenshot button on the Snip app or enter the keyboard shortcut /.
3. Click and drag the crop box around your desired equation, release to Snip.
4. Check your Snip result, then click the Copy PNG button to copy the image to your clipboard.
1. Now click into your Typora document where you would like to insert your equation and enter the shortcut / to paste.
5. You will see a small menu with an option to Zoom or Zoom to 12%. Use this option to change the size of the image in your document.

### Math Blocks

You can render LaTeX mathematical expressions using MathJax.

To add a mathematical expression, input and press the ‘Return’ key. This will trigger an input field which accepts Tex/LaTex source. For example: [ mathbf{V}_1 times mathbf{V}_2 = begin{vmatrix} mathbf{i} & mathbf{j} & mathbf{k} \\ frac{partial X}{partial u} & frac{partial Y}{partial u} & 0 \\ frac{partial X}{partial v} & frac{partial Y}{partial v} & 0 \\ end{vmatrix} ]

In the markdown source file, the math block is a LaTeX expression wrapped by a pair of ‘$$’ marks:  1234567$$mathbf{V}_1 times mathbf{V}_2 = begin{vmatrix}mathbf{i} & mathbf{j} & mathbf{k} \\frac{partial X}{partial u} & frac{partial Y}{partial u} & 0 \\frac{partial X}{partial v} & frac{partial Y}{partial v} & 0 \\end{vmatrix}$$You can find more details here. In typora, you could just press and key to input a math block, in input mode, use Up/Down arrow key or / + key to finish editing, or just click the ✓ button, or somewhere else. ### Inline Math First of all, please enable inline math feature from preferences panels -> Markdown section. Preferences panel can be opened From menu bar: -> , or use shortcut key — / + .

You could add new commands using or. For example:  12345$$defbold#1bold{this is now bold}$$### Chemistry Expressions Typora has the built-in mhchem extension, which can be used to render Chemistry Expressions, you could use like this:  1 ce{CH4 + 2 left( ce{O2 + 79/21 N2} right)} ​ (ce{Hg^2+ ->[I-] HgI2 ->[I-] [Hg^{II}I4]^2-}) (ce{[{(X2) 3}2]^3+}) Which will be rendered as For more details, please refer https://mhchem.github.io/MathJax-mhchem/. ### Cross Reference Typora supports TeX-style reference syntax, for example:  1234567 Here is a labeled equation:$$x+1oversqrt{1-x^2}label{ref1}$$This is a referece : ref{ref1} Here is a labeled equation: [ x+1oversqrt{1-x^2}label{ref1} ] This is a referece : (ref{ref1}) ### Auto Numbering Typora supports auto-numbering math blocks. To turn on this feature, please open preferences panel, and enable “Auto Numbering Math Equations” under “Markdown” section. img ### Troubleshooting ### Force Refresh When Math rendering goes wrong, like output math too wild/narrow, or equation numbering becomes incorrect, you can triple force refresh for all math from → menu. ### Limitations Sours: https://www.dazhuanlan.com/tahao/topics/959020 ## Math typora ### Overview Markdown is created by Daring Fireball; the original guideline is here. Its syntax, however, varies between different parsers or editors. Typora try to follow GitHub Flavored Markdown, but may still have small incompatibilities. Table of Contents ### Block Elements ### Paragraph and line breaks A paragraph is simply one or more consecutive lines of text. In markdown source code, paragraphs are separated by two or more blank lines. In Typora, you only need one blank line (press once) to create a new paragraph. Press + to create a single line break. Most other markdown parsers will ignore single line breaks, so in order to make other markdown parsers recognize your line break, you can leave two spaces at the end of the line, or insert . Headers use 1-6 hash () characters at the start of the line, corresponding to header levels 1-6. For example: In Typora, input ‘#’s followed by title content, and press key will create a header. Or type ⌘1 to ⌘6 as a shortcut. ### Blockquotes Markdown uses email-style > characters for block quoting. They are presented as: In Typora, typing ‘>’ followed by your quote contents will generate a quote block. Typora will insert a proper ‘>’ or line break for you. Nested block quotes (a block quote inside another block quote) by adding additional levels of ‘>’. ### Lists Typing will create an unordered list. (The symbol can be replace with or .) Typing will create an ordered list. For example: ### Task List Task lists are lists with items marked as either [ ] or [x] (incomplete or complete). For example: You can change the complete/incomplete state by clicking on the checkbox before the item. ### (Fenced) Code Blocks Typora only supports fences in GitHub Flavored Markdown, not the original code block style. Using fences is easy: type  and press . Add an optional language identifier after  and Typora runs it through syntax highlighting: ### Math Blocks You can render LaTeX mathematical expressions using MathJax. To add a mathematical expression, enter and press the ‘Return’ key. This will trigger an input field which accepts Tex/LaTex source. For example: $\mathbf{V}_1 \times \mathbf{V}_2 = \begin{vmatrix} \mathbf{i} & \mathbf{j} & \mathbf{k} \\ \frac{\partial X}{\partial u} & \frac{\partial Y}{\partial u} & 0 \\ \frac{\partial X}{\partial v} & \frac{\partial Y}{\partial v} & 0 \\ \end{vmatrix}$ In the markdown source file, the math block is a LaTeX expression wrapped by a pair of ‘$$’ marks:

You can find more details here.

### Tables

Standard Markdown has been extended in several ways to add table support., including by GFM. Typora supports this with a graphical interface, or writing the source code directly.

Enter and press the key. This will create a table with two columns.

After a table is created, placing the focus on that table will open up a toolbar for the table where you can resize, align, or delete the table. You can also use the context menu to copy and add/delete individual columns/rows.

The full syntax for tables is described below, but it is not necessary to know the full syntax in detail as the markdown source code for tables is generated automatically by Typora.

In markdown source code, they look like:

You can also include inline Markdown such as links, bold, italics, or strikethrough in the table.

By including colons () within the header row, you can set text in that column to be left-aligned, right-aligned, or center-aligned:

A colon on the left-most side indicates a left-aligned column; a colon on the right-most side indicates a right-aligned column; a colon on both sides indicates a center-aligned column.

MultiMarkdown extends standard Markdown to provide two ways to add footnotes.

You can create reference footnotes like this1 and this2.

will produce:

Hover over the ‘fn1’ or ‘fn2’ superscript to see content of the footnote. You can use whatever unique identified you like as the footnote marker (e.g. “fn1”).

Hover over the footnote superscripts to see content of the footnote.

### Horizontal Rules

Entering or on a blank line and pressing will draw a horizontal line.

### YAML Front Matter

Typora now supports YAML Front Matter. Enter at the top of the article and then press to introduce a metadata block. Alternatively, you can insert a metadata block from the top menu of Typora.

Enter and press the key to create a “Table of Contents” section. The TOC extracts all headers from the document, and its contents are updated automatically as you add to the document.

### Span Elements

Span elements will be parsed and rendered right after typing. Moving the cursor in middle of those span elements will expand those elements into markdown source. Below is an explanation of the syntax for each span element.

Markdown supports two styles of links: inline and reference.

In both styles, the link text is delimited by [square brackets].

To create an inline link, use a set of regular parentheses immediately after the link text’s closing square bracket. Inside the parentheses, put the URL where you want the link to point, along with an optional title for the link, surrounded in quotes. For example:

will produce:

This is an example inline link. ()

This link has no title attribute. ()

To create an internal link that creates a ‘bookmark’ that allow you to jump to that section after clicking on it, use the name of the header element as the href. For example:

Reference-style links use a second set of square brackets, inside which you place a label of your choosing to identify the link:

In Typora, they will be rendered like so:

This is an example reference-style link.

The implicit link name shortcut allows you to omit the name of the link, in which case the link text itself is used as the name. Just use an empty set of square brackets — for example, to link the word “Google” to the google.com web site, you could simply write:

### URLs

Typora allows you to insert URLs as links, wrapped by brackets. For example becomes [email protected].

Typora will also automatically link standard URLs (for example: www.google.com) without these brackets.

### Images

Images have similar syntax as links, but they require an additional char before the start of the link. The syntax for inserting an image looks like this:

You are able to use drag and drop to insert an image from an image file or your web browser. You can modify the markdown source code by clicking on the image. A relative path will be used if the image that is added using drag and drop is in same directory or sub-directory as the document you’re currently editing.

If you’re using markdown for building websites, you may specify a URL prefix for the image preview on your local computer with property in YAML Front Matter. For example, Enter in YAML Front Matter, and then will be treated as in Typora.

### Emphasis

Markdown treats asterisks () and underscores () as indicators of emphasis. Text wrapped with one or will be wrapped with an HTML tag. For example:

produces:

single asterisks

single underscores

GFM will ignore underscores in words, which is commonly used in code and names, like this:

wow_great_stuff

do_this_and_do_that_and_another_thing.

To produce a literal asterisk or underscore at a position where it would otherwise be used as an emphasis delimiter, you can backslash escape it with a backslash character:

Typora recommends using the symbol.

### Strong

A double or will cause its enclosed contents to be wrapped with an HTML tag, e.g:

produces:

double asterisks

double underscores

Typora recommends using the symbol.

### Code

To indicate an inline span of code, wrap it with backtick quotes (). Unlike a pre-formatted code block, a code span indicates code within a normal paragraph. For example:

will produce:

Use the function.

### Strikethrough

GFM adds syntax to create strikethrough text, which is missing from standard Markdown.

becomes

### Emoji :happy:

Enter emoji with syntax . To make it easier, an auto-complete helper will pop up after typing and the start of an emoji name.

Entering UTF-8 emoji characters directly is also supported by going to -> in the menu bar.

### Inline Math

To use this feature, please enable it first in the tab of the preference panel. Then, use to wrap a LaTeX command. For example: .

To trigger inline preview for inline math: input “”, then press the key, then input a TeX command. You can find more details here. ### Subscript To use this feature, please enable it first in the tab of the preference panel. Then, use to wrap subscript content. For example: , / ### Superscript To use this feature, please enable it first in the tab of the preference panel. Then, use to wrap superscript content. For example: . ### Highlight To use this feature, please enable it first in the tab of the preference panel. Then, use to wrap highlight content. For example: . ### HTML You can use HTML to style content what pure Markdown does not support. For example, use to add text with red color. ### Underlines Underline isn’t specified in Markdown of GFM, but can be produced by using underline HTML tags: becomes Underline. ### Embed Contents Some websites provide iframe-based embed code which you can also paste into Typora. For example: ### Video You can use the HTML tag to embed videos. For example: ### Other HTML Support You can find more details here.

So you should use Latex syntax to render Mathematics expressions. In typora, you could just press and Return key to input a math block. But in your case, you need inline math. Press and make sure inline math is checked. To use inline math, put your content between. For example results

If you write following in Typora

It looks like,

Here results multiplication dot (), results and results fractions.

See all the Latex Math Symbols and difference between dot characters.
