LaTeX snippets to try
Fractions and roots: $$\frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$. Sums and integrals: $$\sum_{i=1}^{n} i = \frac{n(n+1)}{2}$$. Matrices need no packages: $$\begin{pmatrix} a & b \\ c & d \end{pmatrix}$$. Greek inline: $\alpha, \beta, \pi, \Omega$.
What it is for
Homework and exam prep, drafting paper equations, checking a formula before pasting it into a document, and making math images for slides, forums, and chat. It is a lighter, instant alternative to a full LaTeX install: there is no preamble, no compiling, and no account. Students type practice problems, teachers make question sheets, and anyone can jot the surrounding notes next door. For solved equations with steps instead of typesetting, use the quadratic formula calculator.
