Math symbols to copy and paste
Typing maths on a normal keyboard is hard. Where is the square root √, the not equal sign ≠ or the infinity sign ∞? This page has more than 950 math symbols, from simple operators like ± × ÷ to set theory ∈ ∪, logic ∀ ∃ ¬, calculus ∫ ∂ ∑ and hundreds of advanced relation signs.
Tap a symbol to copy it, then paste it into homework, a report, a Google Doc, a chat with your study group or a line of code.
Most used math symbols
- Operators: + − × ÷ ± ∓ · for basic arithmetic.
- Comparison: = ≠ ≈ < > ≤ ≥ ≡ for equations and inequalities.
- Roots and powers: √ ∛ ∜ ² ³ for algebra.
- Calculus: ∫ ∬ ∂ ∇ ∑ ∏ ∞ lim for higher maths.
- Sets: ∈ ∉ ⊂ ⊆ ∪ ∩ ∅ ℕ ℤ ℝ for set theory.
- Logic: ∧ ∨ ¬ ⇒ ⇔ ∀ ∃ for proofs.
- Geometry: ∠ ⊥ ∥ ° △ ≅ for shapes and angles.
Who needs math symbols?
Students use them for homework and online tests. Teachers use them to write worksheets and quiz questions. Engineers and scientists use them in reports and emails. Programmers use them in comments and documentation. Even shoppers use × for sizes like 6 × 4 and ± for measurements. Whenever you would otherwise write “not equal to” or “square root of”, a single symbol is cleaner and faster to read.
Math symbols in Word, Google Docs and chats
Word and Google Docs have equation tools, but they can be slow for one quick symbol. Copying a math symbol here and pasting it straight into your sentence is often quicker. It also works in places with no equation tool at all, like WhatsApp, Discord, email, Slack, Excel cells and online forms.
If you write maths for the web, open a symbol with the i button to copy its HTML entity. If you use LaTeX, the symbol’s official name helps you find the matching command.
Letters used in maths
Maths also uses many letters. Greek letters like π, θ, α, β, λ, σ and Δ are common in formulas. Double-struck letters like ℝ for real numbers and ℕ for natural numbers, and script letters like ℒ and ℱ, are used in higher maths. You can find these by searching their names or by browsing the letters and fancy font letters pages.
Find a symbol by name
Type what the symbol does, like “approximately”, “integral”, “element of” or “therefore”, and it appears right away. You can also search by code point, such as U+221E for infinity ∞. The full category is large, so search saves a lot of scrolling.
Frequently asked questions
- How do I type the square root symbol?
- Copy √ from this page and paste it. On Windows you can also try Alt + 251 in some programs, and on a Mac Option + V.
- What is the symbol for not equal?
- The not equal sign is ≠. On a Mac you can type it with Option + =.
- What does ∴ mean?
- ∴ means “therefore”. Its opposite, ∵, means “because”.
- Can I use these symbols in Excel?
- Yes. You can paste them into cells as text. For calculations Excel still uses its own operators like * and /.
- How do I type the infinity symbol?
- Copy ∞ from this page. On a Mac press Option + 5, and on Windows try Alt + 236 in some programs.
- What does ≈ mean?
- ≈ means “approximately equal to”, used when two values are close but not exactly the same.
- What is the pi symbol?
- π is the Greek small letter pi. It stands for the ratio of a circle’s circumference to its diameter, about 3.14159.
