Math Symbols
Copy and paste Unicode math signs for scientific writing, equations, and technical notation
Math symbols are Unicode characters typically used in scientific writing, education, and technical documents to represent operations, relationships, and notation across many areas of mathematics. This page includes math keyboard text symbols plus math emoticons, emojis, and symbols that you can copy and paste into any application. You will commonly see characters such as ∂, ∃, √, and ≥ used to express calculus, logic, roots, and inequalities in plain text.
How to Copy and Paste Math Symbols
Browse the math symbols grid to locate the characters you need for your equation or notation. Select a symbol to place it into the editor, then copy it and paste it into documents, messages, notes, or math-enabled apps.
What Are Math Symbols?
A math symbol is a Unicode text character used to write or annotate mathematical expressions in plain text. These symbols are commonly used to represent arithmetic operations, comparisons, set relationships, calculus notation, geometry marks, and other mathematical ideas. Depending on context, the same character can be used in different ways, but symbols like √, ∫, ≤, and ∠ are often used to format equations and statements clearly across software and platforms.
Popular Math Symbols
These math symbols are frequently used in coursework, scientific writing, and technical communication. They are commonly selected for quick copy and paste when a standard keyboard does not provide them.
| Symbol | Name |
|---|---|
| ≤ | Less-than or equal to |
| ≥ | Greater-than or equal to |
| √ | Square root |
| ∑ | Summation |
| ∫ | Integral |
| ∂ | Partial derivative |
Math Symbol Categories
Math symbols cover many types of notation. Grouping them by category can make it easier to find the right character for an equation, proof, or technical explanation.
Inequality Symbols
Inequality symbols are typically used to compare values and express bounds or constraints in algebra, statistics, and scientific writing.
≤ ≥ ≠ ≈ ≱
Integral Symbols
Integral symbols are commonly used in calculus and physics to represent integration, surface integrals, and contour integrals depending on notation.
∫ ∬ ∭ ∮
Differentiation Symbols
Differentiation symbols are often used to express derivatives, partial derivatives, and rate-of-change notation in calculus and applied math.
∂ d ∇
Geometry Symbols
Geometry symbols are typically used in diagrams, problem statements, and proofs to indicate angles and related geometric notation.
∠ ∢ ⟂
Exponents and Constants
These symbols are commonly used for exponential notation and mathematical constants in formulas and technical text.
ℯ π
Root and Power Symbols
Root symbols are often used to represent square roots and higher-order roots in algebra and engineering notation.
√ ∛ ∜
Arithmetic Operators
Arithmetic symbols are used to write calculations and operations, especially when users want visually clear operators in plain text.
➕ ➖ ➗ ✖ ±
Math Symbol Usage Examples
Math symbols are frequently used in notes, assignments, and technical messages where formatting matters. The examples below show how math symbols may appear in everyday text.
Study Notes
If x ≥ 0, then √x is defined for real numbers.
Homework Statement
Solve for x where x ≠ 0 and x ≤ 5.
Calculus Notation
Use ∂f/∂x to indicate a partial derivative with respect to x.
Physics / Engineering
Work can be written using an integral: ∫ F · dx (notation varies by context).
Geometry
In the diagram, ∠ABC is marked as a right angle: ∠ABC = 90° (depending on conventions).
Using Math Symbols on Social Media and Online Platforms
Math symbols can be used in posts, bios, messages, and educational content where clear notation is helpful. Because these characters are Unicode, they are commonly compatible across many apps and operating systems, although appearance may vary by font. People often paste math symbols into captions, comments, and explanations to keep expressions readable without special equation editors.

Unicode Math Symbols and Meanings
Mathematical symbols are encoded in Unicode so they can be copied, stored, and displayed consistently across systems. Each symbol has an assigned code point and an official name; the way it is interpreted is commonly determined by the surrounding math notation, field of study, and formatting conventions.
