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*}
