LaTeX Basics
Inline Math: Use $...$ for inline mathematical expressions
Display Math: Use $$...$$ for centered, display-style equations
Fractions: \frac{numerator}{denominator}
Powers: x^{n} or x^n for single character
Subscripts: x_{n} or x_n for single character
Square Roots: \sqrt{x} or \sqrt[n]{x} for nth root
Sums: \sum_{i=1}^{n} x_i
Integrals: \int_{a}^{b} f(x) dx
Matrices: Use \begin{matrix} ... \end{matrix}
Keyboard Shortcuts

Common Examples
Quadratic Formula: $x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$
Pythagorean Theorem: $a^2 + b^2 = c^2$
Integral: $$\int_{0}^{\infty} e^{-x^2} dx = \frac{\sqrt{\pi}}{2}$$
Matrix: $$\begin{pmatrix} a & b \\ c & d \end{pmatrix}$$
Sum: $$\sum_{i=1}^{n} i = \frac{n(n+1)}{2}$$
Tips & Tricks
- Use the symbol panel for quick insertion of common mathematical symbols
- Double-click on symbol buttons to insert them at cursor position
- Use display math mode (
$$...$$) for standalone equations
- Use inline math mode (
$...$) for equations within text
- Escape special characters with a backslash:
\$, \%, \&
- Add spaces with
\quad or \qquad
- The auto-save feature ensures you never lose your work
Technical Details
This editor uses CodeMirror for syntax highlighting and code editing. Mathematical rendering is powered by MathJax 3, which provides beautiful, publication-quality mathematical typesetting. All code is stored locally in your browser using localStorage, ensuring privacy and persistence.
