Calculus and Differential Symbols
Copy integrals, differential operators, differentials, sums, and infinity for equations and technical notes.
The essential calculus marks live together here, including the plain-text differentials that are usually needed in the same line as an integral.

Accurate use
Technical and compatibility guide
This page is for building short calculus expressions in plain text: operators such as ∫ and ∂ plus the differentials, bounds, and variables that give them meaning.
| Character | Unicode | HTML | LaTeX |
|---|---|---|---|
| ∫Integral | U+222B | ∫ | \int |
| ∂Partial differential | U+2202 | ∂ | \partial |
| ∇Nabla | U+2207 | ∇ | \nabla |
| ∑N-ary summation | U+2211 | ∑ | \sum |
Common mistakes
- An integral sign alone is incomplete notation for most uses; include the integrand and a differential such as dx.
- Do not replace ∂ with a stylized d, or ∑ with the Greek capital letter Σ: they are different Unicode characters with different mathematical roles.
Word, Docs, Notion, and plain text
Simple expressions paste into Word, Google Docs, Notion, and plain text. Use an equation object for stacked limits or fractions; Notion equations use KaTeX, so confirm that a LaTeX command is supported before relying on it.

Frequently asked questions
How do I copy these symbols?
Press any large symbol card or snippet. Quick Symbols copies it immediately and adds it to the copy tray, where you can combine several items.
Can I use these in Notion or Google Docs?
Yes. These are standard text characters, so you can paste them into Notion, Google Docs, email, notes, and most other text fields.
Do these work in Microsoft Word?
Yes. Paste them into Word like ordinary text. Their exact appearance can vary slightly with the selected font.
What is the difference between similar symbols?
The groups on this page explain the practical differences between the calculus symbols shown here, including which forms fit common notes and equations.
