XHTML Symbols

  • Below is a quick reference for Logic and Mathematics symbols in XHTML which work on all modern browsers
  • These are intended for logical and mathematical articles, or any page requiring special characters not found in the "edit bar"
  • Feel free to copy-and-paste (ctrl/cmd-c, ctrl/cmd-v) symbols




Logic: ¬ ∧ ∨ ∃ ∀ ¬ ∧ ∨ ∃ ∀
