Markdown math formula editor

Write a maths formula the easy way. Type in the live equation field, or click a construct, and the tool builds clean LaTeX you can drop straight into your document.

LaTeX math basics

The formula is stored as LaTeX, the standard way to write maths as text. You never have to remember it: type in the equation field above and it writes the LaTeX for you. This section shows what the common pieces look like so you can read and tweak them by hand.

Fractions and roots

A fraction is \frac{top}{bottom}. A square root is \sqrt{x}, and \sqrt[n]{x} gives an nth root.

You write

\frac{a + b}{2} = \sqrt{c}

You get

Powers and subscripts

A superscript is ^ and a subscript is _. Wrap more than one character in braces, like x^{2n}.

You write

E = mc^2 \quad a_{n+1} = a_n + d

You get

Sums and integrals

Big operators take their range with _ for the lower bound and ^ for the upper one.

You write

\sum_{i=1}^{n} i = \frac{n(n+1)}{2}

You get

Greek letters and matrices

Greek letters are named commands like \alpha and \pi. A matrix goes inside \begin{pmatrix} ... \end{pmatrix}, with & between columns and \\ between rows.

You write

\theta = \begin{pmatrix} \cos\alpha & -\sin\alpha \\ \sin\alpha & \cos\alpha \end{pmatrix}

You get

This editor

Type directly in the equation field to build the formula visually. The tools insert whole constructs at the caret, and the Properties panel holds the raw LaTeX and a display or inline mode toggle. The Source tab shows the LaTeX on its own, so you can paste a formula in or copy one out. Copy or download gives you a Markdown block fenced as math.
