Logical Or ∨

The Logical Or character (∨) is a standard HTML entity defined in the HTML specification. In HTML source code, it can be written using the named entity reference ∨, the decimal numeric character reference ∨, or the hexadecimal numeric reference ∨. The character is assigned Unicode code point U+2228 in the Universal Character Set.

The logical OR symbol (vee or disjunction) represents the disjunction operation in mathematical logic and Boolean algebra. It returns true when at least one operand is true. The vee shape points downward and is a foundational symbol in propositional logic, circuit design, and programming theory.

Mathematical HTML entities enable web authors to display proper mathematical notation without relying on images or specialized rendering libraries like MathJax or KaTeX. While complex equations and multi-line formulas may still benefit from dedicated math typesetting tools, individual symbols expressed as HTML entities render quickly, remain accessible to screen readers, and can be styled with CSS just like regular text content.

When deciding how to encode the Logical Or character in your HTML documents, the named entity ∨ is generally the most readable choice for developers reviewing or maintaining source code. The decimal form ∨ and hexadecimal form ∨ are equally valid alternatives that work in contexts where named entities may not be supported, or when generating HTML output programmatically from server-side code. All three representations produce identical visual output in every modern web browser.

Use the logical OR symbol in Boolean expressions, truth tables, digital logic documentation, and formal specifications. It represents the same concept as the || operator in programming languages. Together with ∧ and ¬, it forms the core set of Boolean logic operators.
