Math Symbols — Copy & Paste with LaTeX Codes

Copy and paste math symbols — operators, relations, set and logic notation, calculus signs, geometry marks, Greek letters, superscripts, subscripts and fractions — with a plain-English meaning for each. Every symbol also shows its LaTeX command, Unicode code point and HTML entity, so the same page works whether you are writing homework in a word processor, a paper in LaTeX or an equation on a web page.

How to use this tool

1. Pick a category, or keep Most used.
2. Search by name or meaning (integral, subset, approximately), or type a LaTeX command such as \leq.
3. Paste a symbol you found elsewhere to find out what it is and how to write it in LaTeX.
4. Copy the symbol, or the code you need, from the results or the table.

Formula

HTML decimal code = &# + code point in decimal + ;

≤ is U+2264; hexadecimal 2264 is 2×4096 + 2×256 + 6×16 + 4 = 8804, so it can be written ≤ or ≤ in HTML. In LaTeX you use the command instead of the character, inside math mode: $a \leq b$. Commands marked amssymb need \usepackage{amssymb}.

Example

Typing \leq returns ≤, "Less-than or equal to", U+2264, ≤ and ≤. Searching integral gives ∫ with the LaTeX command \int and decimal code ∫. The Fractions category shows 18 ready-made fractions from ½ to ⅒, each with its decimal value, plus the fraction slash ⁄ for building others.
