Getting Started with LaTeX Math: A Complete Beginner's Guide

LaTeX is the gold standard for writing mathematical notation in academic and scientific documents. This guide will walk you through everything you need to get started.

What is LaTeX?

LaTeX (pronounced "LAY-tek" or "LAH-tek") is a document preparation system widely used in academia for its superior handling of mathematical notation. Unlike word processors, LaTeX uses plain text markup to describe document structure and mathematical expressions.

Basic Math Syntax

In LaTeX, inline math is enclosed in $...$ and display math in $$...$$. Our editor handles the rendering automatically — just type the LaTeX code and see the result instantly.

Your First Formula

Try typing this in the editor: E = mc^2. The caret ^ creates a superscript. For subscripts, use underscore: a_n.

Fractions and Roots

Fractions use \frac{numerator}{denominator}. Square roots use \sqrt{expression}. For nth roots: \sqrt[n]{expression}.

Greek Letters

Greek letters are written with a backslash prefix: \alpha, \beta, \gamma, \pi, \Sigma, \Omega, etc. Use uppercase first letter for capital Greek letters.

Integrals and Sums

Integrals: \int_{a}^{b} f(x) \, dx. Sums: \sum_{i=1}^{n} x_i. Products: \prod_{i=1}^{n} x_i. The \, adds thin spacing.

Matrices

Matrices are created with \begin{matrix} ... \end{matrix}. Use & to separate columns and \\ for rows. Try pmatrix, bmatrix, or vmatrix for different bracket styles.
