==Mathematical Symbols==
This page is a quick reference for the "standard" mathematical symbols in [[HTML]] that should work on most browsers, and is intended mainly for people editing mathematical articles on Wikipedia.
*'''Numbers:''' {{unicode|¼ ½ ¾ ¹ ² ³}} ¼ ½ ¾ ¹ ² ³
*'''Analysis:''' {{unicode|∂ ∫ ∑ ∏ √ ∞ ∇ ℘ ℑ ℜ}} ∂ ∫ ∑ ∏ √ ∞ ∇ ℘ ℑ ℜ
*'''Arrows:''' {{unicode|← ↓ → ↑ ↔ ↵ ⇐ ⇓ ⇒ ⇑ ⇔}} ← ↓ → ↑ ↔ ↵ ⇐ ⇓ ⇒ ⇑ ⇔
*'''Logic:''' {{unicode|¬ ∧ ∨ ∃ ∀}} ¬ ∧ ∨ ∃ ∀
*'''Sets:''' {{unicode|∈ ∉ ∋ ∅ ⊆ ⊇ ⊃ ⊂ ⊄ ∪ ∩ ℵ}} ∈ ∉ ∋ ∅ ⊆ ⊇ ⊃ ⊂ ⊄ ∪ ∩ ℵ
*'''Relations:''' {{unicode|≠ ≤ ≥ < > ≡ ≅ ≈ ∝}} &ne; &le; &ge; &lt; &gt; &equiv; &cong; &asymp; &prop;
*'''Binary operations:''' {{unicode|± − × ÷ ⁄ ⊥ ⊕ ⊗ ∗}} &plusmn; &minus; &times; &divide; &frasl; &perp; &oplus; &otimes; &lowast;
*'''Delimiters:''' {{unicode|⌈ ⌉ ⌊ ⌋ ⟨ ⟩ « »}} &lceil; &rceil; &lfloor;&rfloor; &lang; &rang; &laquo; &raquo;
*'''Miscellaneous:''' {{unicode|† ¦ ∠ ∴ ◊ • ♠ ♣ ♥ ♦}} &dagger; &brvbar; &ang; &there4; &loz; &bull; &spades; &clubs; &hearts; &diams;
*'''Punctuation:''' {{unicode|′ ″ ‾ ˆ ° ⋅ · … – —}} &prime; &Prime; &oline; &circ; &deg; &sdot; &middot; &hellip; &ndash; &mdash;
*'''Spacing:''' thin ( ), n-width ( ), m-width ( ), and non-breaking spaces ( ). &thinsp; &ensp; &emsp; &nbsp;
*'''Greek:''' α β γ Α Β Γ etc. &alpha; &beta; &gamma; &Alpha; &Beta; &Gamma; etc.
*'''Unicode:''' &#x22A2; (for example) gives the character ⊢ with [[unicode]] number x22A2 (hexadecimal). Warning: many of the more obscure unicode characters do not yet work on all browsers.
It might be easier to just copy and paste the symbols instead of using them by reference.
