Math Signs & Symbols — Copy and Paste

Copy common math signs and symbols for equations, notes, code, and documents. Choose a character to copy it instantly, then open its page when you need its meaning, Unicode code point, HTML entity, or LaTeX command.

Common math signs and symbols

Choose a sign or symbol to copy it instantly, or open its page for its meaning, Unicode, HTML, LaTeX, and practical examples.

Calculation & measurement

For quantities, arithmetic, dimensions, and uncertainty.

Comparison & approximation

For bounds, conditions, estimates, and statements of equality.

Formula & set notation

For roots, limits, sums, and membership in a set.

When to use common math signs and symbols

Use calculation and measurement symbols for expressions such as 90°, 12.0 ± 0.2, 3 × 4, and 8 ÷ 2. Comparison symbols express mathematical conditions and boundaries, as in n ≥ 1, a ≠ b, and π ≈ 3.1416. Formula and set notation rely on √ for roots, ∞ for limits, ∈ for set membership, and ∑ for summations.

Copy, Unicode, HTML, and LaTeX

For everyday writing, copy the character itself to paste standard Unicode. When working in web markup or scientific papers, each symbol page provides its hexadecimal code point along with the official HTML entity and LaTeX math command.

Math symbols FAQ

How do I copy a math sign or symbol?

Use the copy button on a card, then paste the character into your document, chat, or code editor. Open the symbol page when you also need its code or command.

Should I use a Unicode character, HTML entity, or LaTeX command?

Use the copied Unicode character in normal text. Use an HTML entity when you need to write the character safely in markup, and use the LaTeX command when you are writing a LaTeX formula.

Why does the same math symbol look different in another app?

Fonts choose the visual shape of a Unicode character. The copied character and its code point stay the same, but its weight, spacing, or style can change with the font.
