# Beautiful Math with LaTeX

LaTeX is a powerful markup language for writing complex mathematical equations, formulas, and more. Jetpack combines the power of LaTeX and the simplicity of WordPress to give you the ultimate in math blogging platforms.

Wow, that sounds nerdy.

### Using LaTeX

To include $LaTeX$ code in your post, use the following:

`\$``latex your-latex-code-here\$`

So, for example,

`\$``latex ihbarfrac{partial}{partial t}left|Psi(t)right>=Hleft|Psi(t)right>\$`

produces $ihbarfrac{partial}{partial t}left|Psi(t)right>=Hleft|Psi(t)right>$

### LaTeX Error

If your $LaTeX$ code is broken, instead of the equation you'll see an ugly yellow and red error message. Sorry, we can't provide support for $LaTeX$ syntax, but there are plenty of useful guides elsewhere online. Or a quick post in our forums might find you a solution. One thing to keep in mind is that WordPress puts all of your $LaTeX$ code inside a $LaTeX$ `math` environment. If you try to use $LaTeX$ that doesn't work inside the `math` environment (such as `begin{align} ... end{align}`), you will get an error: $LaTeX&s=X$

### LaTeX Size

You can change the size of the LaTeX by specifying an `s` parameter after the $LaTeX$ code.

`\$``latex LaTeX&s=X\$`

Where X goes from -4 to 4 (0 is the default). These sizes correspond to $LaTeX$'s font size commands:

`s=` font size Example
-4 `tiny` $LaTeX$
-3 `scriptsize` $LaTeX$
-2 `footnotesize` $LaTeX$
-1 `small` $LaTeX$
0 `normalsize (12pt)` $LaTeX$
1 `large` $LaTeX$
2 `Large` $LaTeX$
3 `LARGE` $LaTeX$
4 `huge` $LaTeX$

### LaTeX Colors

WordPress tries to guess the background and foreground colors of your site and generates the $LaTeX$ image accordingly. But, you can change the colors. You can specify `bg` and `fg` parameters after the $LaTeX$ code to change the background and foreground colors, respectively. The colors must be in hexadecimal RGB format: `ffffff` for white, `0000ff` for bright blue, etc.

`\$``latex LaTeX&bg=ffcccc&fg=cc00ff&s=4\$` $LaTeX$

### LaTeX Packages

WordPress.com uses standard $LaTeX$ with the following packages:

• amsmath
• amsfonts
• amssymb

For more information about $LaTeX$, you can visit LaTeX documentation site and TeX Resources by American Mathematical Society.
