NOR (⊽) is the Mathematical Operators character at Unicode U+22BD (NOR). It marks the Boolean not-or operation — true only when both inputs are false. Used in logic gates and Boolean algebra. HTML5 provides the named entity ⊽.
Remember
Character ⊽
Unicode U+22BD
Named entity ⊽
Hex entity ⊽
Decimal ⊽
CSS escape \22BD
All of these produce the same glyph: ⊽. Prefer ⊽ for readable HTML; paste ⊽ in UTF-8 when convenient.

How It Works
1. Named:⊽ is the clearest HTML form for U+22BD.
2. Hex:U+22BD → ⊽ in HTML. Reliable numeric form.
3. Decimal: same code point as 8893 → ⊽. Same glyph.
4. Direct: paste ⊽ in a UTF-8 file with <meta charset="UTF-8">.
5. CSS: use \22BD in content (not an HTML entity). #point::after appends that ⊽ after the paragraph text.
Pitfalls & Tips
Common mistakes when working with the NOR entity.
Meaning
NOR ≠ OR
⊽ is not-or. Plain OR is ∨ (∨). Mixing them changes the formula.
Named
Prefer ⊽
There is no short &nor; name for this glyph in HTML5 — use ⊽.
CSS vs HTML
Do not mix escapes
\22BD belongs in CSS. ⊽ / ⊽ / ⊽ belong in HTML.
Look-alikes
Not ∨ or ⊼
∨ is OR; ⊼ is NAND. NOR is U+22BD.
Semicolon
End references
Always finish with ; — write ⊽, not &barvee.
UTF-8
Declare charset
If you paste ⊽ directly, serve the page as UTF-8 with <meta charset="UTF-8">.
Compatibility
Browser Support
NOR (U+22BD) and its entity forms (⊽, ⊽, ⊽, CSS \\22BD) are supported in all mainstream browsers. Glyph availability depends on the font.
✓ Universal support
NOR (⊽)
Prefer ⊽, or encode with hex, decimal, or CSS escape — same glyph everywhere.

Bottom line: Prefer ⊽ in HTML. Use ⊽ / ⊽ when a numeric form is required, and \\22BD only inside CSS content.

Key Takeaways
Unicode: NOR is U+22BD (decimal 8893), Mathematical Operators.
Use ⊽ (named), ⊽ (hex), ⊽ (decimal), type ⊽ in UTF-8, or the CSS escape \22BD in content. All render ⊽.
U+22BD (NOR). Hex 22BD, decimal 8893. It belongs to Mathematical Operators and represents the Boolean NOR (not-or) operation.
Yes. HTML5 defines ⊽ for this character. You can also use ⊽ or ⊽.
Use it in Boolean algebra, logic-gate diagrams, or digital-electronics notes. Prefer ⊽ for readable source. For ordinary English, write “NOR” in words.
HTML entities (⊽, ⊽, or ⊽) go in markup. The CSS escape \22BD is used in stylesheets (usually in the content property of ::before/::after). Both render ⊽.
OR is U+2228 (∨). NAND is U+22BC. NOR is U+22BD (⊽) — not-or. Do not substitute one for another.

Did you know?
NOR (⊽) is Unicode U+22BD (decimal 8893) — NOR in Mathematical Operators. HTML5 provides ⊽. It denotes the Boolean NOR operation (not-or): true only when both inputs are false. Related symbols include OR (∨, ∨) and NAND (U+22BC).
