How to write LaTeX

LaTeX's math mode makes it simple to write arithmetic in plain text. To enter math mode in LaTeX, you must use one of several commands:

For example:
"$$ E = mc2 $$"

The LaTeX Math macro handles this for you. You only need to enter the math; the equation is rendered automatically.

To help you started, here are a few LaTeX math examples.

`E = mc^2`
`\pi = \frac c d`
`\frac{a + b}{2}`
`e = \lim_{x\to\infty} \left(1+\dfrac{1}{n}\right)^n`
`\begin{matrix} a & b & c \\ d & e & f \\ g & h & i \end{matrix}`
`\begin{align} f(x) &= (x+a)(x+b) \\ &= x^2 + (a+b)x + ab \end{align}`
