此頁列出應用在HTML上、大多數瀏覽器應可支援顯示的「標準」數學符號，主要供撰寫數學條目的維基人參考使用。

  • 數字: ¼ ½ ¾ &frac14; &frac12; &frac34;
  • 分數:½ ⅓ 7/9{{Fraction|1|2 {{Fraction|1|3 {{Fraction|7|9
  • 字形大小: x x   <big>x</big> <small>x</small>
  • 底線文字   underline {{overline|overline  <u> underline </u> {{overline|overline
  • 刪除線文字   strikeout   <s> strikeout </s>
  • 字形: italics  bold  — ''italics''   '''bold'''
  • 通用字形規範: Φ (A)   <span style="font-family: Times New Roman; font-size:100%; font-style:italic; font-weight:bold;"> Φ (A) </span>;
  • 上標/下標符號: x2 x3 x{{su|p=2|b=1  x<sup>2</sup> x<sub>3</sub> x{{su|p=2|b=1;
  • 分析符號: ƒ ∂ ∫ ∑ ∏ √ ∞ ∇ ℘ ℑ ℜ &fnof; &part; &int; &sum; &prod; &radic; &infin; &nabla; &weierp; &image; &real;
  • 箭頭符號: ← ↓ → ↑ ↔ ↵ ⇐ ⇓ ⇒ ⇑ ⇔ &larr; &darr; &rarr; &uarr; &harr; &crarr; &lArr; &dArr; &rArr; &uArr; &hArr;
  • 邏輯符號: ¬ ∧ ∨ ∃ ∀ &not; &and; &or; &exist; &forall;
  • 集合符號: ∈ ∉ ∋ ∅ ⊆ ⊇ ⊃ ⊂ ⊄ ∪ ∩ ℵ &isin; &notin; &ni; &empty; &sube; &supe; &sup; &sub; &nsub; &cup; &cap; &alefsym;
  • 關聯符號: ≠ ≤ ≥ < > ≡ ≢ ∼ ≅ ≈ ∝ &ne; &le; &ge; &lt; &gt; &equiv; &nequiv; &sim; &cong; &asymp; &prop;
  • 二進制運算元: ± − × ÷ ⁄ ⊥ ⊕ ⊗ ∗ &plusmn; &minus; &times; &divide; &frasl; &perp; &oplus; &otimes; &lowast;
  • 分隔符號: ⌈ ⌉ ⌊ ⌋ 〈 〉 « » &lceil; &rceil; &lfloor;&rfloor; &lang; &rang; &laquo; &raquo;
  • 各式符號: † ‡ ¦ ∠ ∴ ◊ • ♠ ♣ ♥ ♦ &dagger; &Dagger; &brvbar; &ang; &there4; &loz; &bull; &spades; &clubs; &hearts; &diams;
  • 標點符號: ′ ″ ‾ ° ⋅ · … – — ˆ &prime; &Prime; &oline; &deg; &sdot; &middot; &hellip; &ndash; &mdash; &circ;
  • 空格表示符號: 窄空格 ( ), n-寬度空格 ( ), m-寬度空格 ( ), and 不换行空格 ( ). &thinsp; &ensp; &emsp; &nbsp;
  • 希臘符號: α β γ Α Β Γ etc. &alpha; &beta; &gamma; &Alpha; &Beta; &Gamma; etc.
  • 萬國碼: 例如輸入 &#x22A2; 即可顯示萬國碼x22A2的 ⊢。提醒：有許多萬國碼字元可能無法在所有的網頁瀏覽器上正確顯示，這亦使頁面源代碼難以閱讀。

有時候直接複製符號可能比加入上述代碼簡單，例如萬國碼中的字母式符号就可以直接複製並加入頁面，像利用 ℝ 代替 &#8477;。點選編輯頁下方列出的符號亦可將符號直接加入頁面。
