Temperature, angles, and coordinates (e.g. 90°, 37°C).

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.
The less-than-or-equal-to sign for inequalities in proofs, code comments, and papers.
The greater-than-or-equal-to sign for bounds and constraints.
The not equal sign for mathematical and logical comparisons.
Rounded results and asymptotic statements.
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.
Similar-looking math signs are not interchangeable
The multiplication sign × is a dedicated math operator, while a plain x is a variable letter. The summation symbol ∑ is an operator distinct from the Greek capital Sigma Σ. Likewise, ∈ means “is an element of,” distinct from the Greek letter epsilon ε. Use the greater-than-or-equal-to sign ≥ or less-than-or-equal-to sign ≤ when equality is allowed, and the not equal sign ≠ when two values differ.
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.
