What You'll Learn

How to display the minus tilde sign (≂) in HTML using hexadecimal, decimal, named entity, and CSS escape methods. This character is U+2242 (MINUS TILDE) in the Mathematical Operators block (U+2200–U+22FF)—a relation symbol used in advanced mathematics and operator notation.

Render it with ≂, ≂, ≂, or CSS escape \2242. Do not confuse ≂ with the tilde operator ∼ (U+223C) or the minus sign − (U+2212)—each is a distinct symbol.

🧠 How It Works

1

Hexadecimal Code

&#x2242; uses the Unicode hexadecimal value 2242 to display the minus tilde sign. The x prefix indicates hexadecimal format.

HTML markup
2

Decimal HTML Code

&#8770; uses the decimal Unicode value 8770 to display the same character.

HTML markup
3

CSS Entity

\2242 is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.

CSS stylesheet
4

Named Entity

&esim; is the standard named HTML entity for the minus tilde sign—easy to read and remember in source markup.

=

Same visual result

All four methods produce (≂). Unicode U+2242 is in Mathematical Operators. Prefer &esim; for readable HTML source.

Use Cases

The minus tilde sign (≂) is commonly used in:

📈 Mathematics

Relation symbols and operator notation in advanced math.

🔬 Science

Scientific papers and formula documentation.

⚙️ Engineering

Technical specs with specialized mathematical notation.

📚 Education

Online courses, textbooks, and math reference content.

💻 Technical docs

API references and scientific documentation sites.

📄 Reference guides

HTML entity tutorials and Unicode symbol documentation.

💡 Best Practices

Do

  • Prefer &esim; for readable HTML source
  • Use ≂ for the correct minus-tilde relation symbol
  • Distinguish ≂ from ∼ (tilde operator) and − (minus)
  • Serve pages with UTF-8 (<meta charset="utf-8">)
  • Consider MathML for complex mathematical formulas

Don’t

  • Confuse ≂ with the ASCII tilde ~ (U+007E)
  • Use ≂ when you mean subtraction minus −
  • Put CSS escape \2242 in HTML text nodes
  • Use HTML entities in JS (use \u2242)
  • Use padded Unicode notation like U+02242—the correct value is U+2242

Key Takeaways

1

Four HTML/CSS references all render ≂

&#x2242; &#8770; &esim;
2

For CSS stylesheets, use \2242 in the content property

Not the same as tilde operator ∼ (U+223C)

❓ Frequently Asked Questions

Use &#x2242; (hex), &#8770; (decimal), &esim; (named), or \2242 in CSS content. All produce ≂.
U+2242 (MINUS TILDE). Mathematical Operators block (U+2200–U+22FF). Hex 2242, decimal 8770. Named HTML entity: &esim;.
For mathematical relations, operator notation in equations, scientific documentation, and content requiring the minus tilde relation symbol.
No. ≂ is U+2242 (MINUS TILDE). ∼ is U+223C (TILDE OPERATOR). They are different mathematical symbols with different meanings and code points.
HTML references (&#8770;, &#x2242;, or &esim;) go directly in markup. The CSS escape \2242 is used in stylesheets, typically in the content property of pseudo-elements. Same visual result, different layers of the stack.
