About
The number row on your keyboard hands you + and -, and one Shift away you'll find =, but the moment an equation needs a real math symbol you're stuck. Multiplication is the classic trap: people reach for the letter x when the real operator is ×, centered and symmetric. Division ÷, plus-or-minus ±, and not-equal ≠ aren't printed on any key at all. Every glyph on this page copies with a single tap, so you can drop the exact character into whatever you're writing instead of faking it with lookalikes.
These are plain Unicode text, not emoji or images, which matters more than it sounds. A ÷ or √ you paste into a Discord message, a Google Doc, an email subject line or an Instagram caption stays the same character everywhere and never turns into a coloured picture or a hollow box on someone else's phone. That makes them safe for helping with math homework in a group chat, dropping a quick formula into a Notion page, or writing a spec that has to read identically on Windows, Mac and Android.
The family of 'equals' signs is where people slip up most. A plain = means exactly equal; ≈ means approximately equal (π ≈ 3.14); ≅ is congruent or approximately equal to, the one you'll see in geometry; and ≡ is identical or equivalent, a stronger claim than =. Pick the one that says what you actually mean — writing ≈ instead of = can be the difference between a rounded answer and a wrong one.
Comparisons need their own symbols too. Less-than-or-equal ≤ and greater-than-or-equal ≥ save you from typing '<=' and hoping the reader fills in the gap, and the full-width ≦ is the shape you'll want inside Chinese text so it lines up with the surrounding characters instead of looking cramped and half-sized.
Roots and infinity round out the set. √ is the everyday square root; ∛ and ∜ are the cube and fourth roots, with the little index already built into the glyph so you don't need a superscript. And ∞ is the infinity sign — handy for limits, for labelling something 'unlimited', or just as a small flourish. Windows alt-code users can also reach ± with Alt+0177, but for most of these characters copying is simply faster.
Frequently asked questions
- How do I type a division sign?
- Tap ÷ on this page to copy it instantly. On Windows you can also hold Alt and type 0247 on the numeric keypad, while on a Mac the shortcut is Option+/ (the slash key).
- How do I type the infinity symbol?
- Copy ∞ here with one tap and it works the same in every app. On a Mac you can type it with Option+5; standard Windows keyboards have no simple shortcut, so pasting the Unicode character is the dependable route.
- How do I type plus-minus ±?
- Copy ± from this page. On Windows, Alt+0177 produces it; on macOS, press Option+Shift+= (the equals key).
- How do I type not-equal ≠?
- Copy ≠ here for a guaranteed result across platforms. On a Mac you can also press Option+= to type it directly; Windows has no simple keyboard shortcut, so pasting is easiest.
- What's the difference between ≈ and ≅?
- ≈ means 'approximately equal to' and is used for rounded values like π ≈ 3.14. ≅ means 'congruent to' or 'approximately equal to' and shows up mainly in geometry when comparing shapes.
- Is the multiplication sign × the same as the letter x?
- No. × is a dedicated math operator that sits centered on the line and is perfectly symmetric, whereas the letter x is narrower and sits on the baseline. For clean equations, copy the real × instead of typing x.
