Math Symbols
Mathematical symbols from the Unicode Mathematical Operators block (U+2200–U+22FF), Latin-1 Supplement and Letterlike Symbols. This page covers arithmetic (± × ÷), comparison (≠ ≤ ≥ ≈ ≡), set theory (∈ ∉ ⊂ ⊆ ∪ ∩ ∅), logic (∀ ∃ ¬ ∧ ∨), calculus (∫ ∂ ∇ ∑ ∏ ∞), roots and powers, and constants like π and ℯ.
Every symbol is a real Unicode character, so it works in Word, Google Docs, email, Slack, LaTeX-free markdown, code comments and social media.

Frequently asked questions
How do I copy math symbols?
Click any symbol on this page to copy it to your clipboard, then paste it anywhere: documents, email, social media, code or chat. Every character here is standard Unicode, so it works across Windows, macOS, iOS, Android and Linux.
How many math symbols are on this page?
This collection contains 58 characters. Each one links to a detail page with its Unicode code point, decimal, hexadecimal and octal values, HTML entity, CSS escape, and JavaScript, Python and Java escape sequences.
How do I type the multiplication sign ×?
The multiplication sign is U+00D7. Type Alt+0215 on Windows, Option+Shift+8 (actually ° — use Option key with Unicode Hex Input and 00D7) on macOS, or use the HTML entity ×. Do not use the letter x, which has different width and spacing.
What is the HTML entity for infinity ∞?
Infinity is ∞ or ∞ (hex ∞). In CSS use content: "\221E"; in JavaScript use "\u221E".
What is the difference between ≈ and ≃ and ≅?
≈ (U+2248, almost equal to) is used for numerical approximation. ≃ (U+2243, asymptotically equal) and ≅ (U+2245, approximately equal / congruent) are used in geometry and abstract algebra to mean isomorphic or congruent.
