For All Symbol
“∀” means “for all” and is commonly used to express universal statements in math and logic.
U+2200
The symbol “∀” (Unicode U+2200) is read as “for all.” It’s widely used in logic and mathematics to indicate a statement holds universally. You can copy it as-is or use its HTML/CSS/JavaScript escapes.
For All Symbol Meaning
The “∀” symbol, pronounced “for all,” is the universal quantifier in formal logic. It indicates that a statement applies to every element in a particular domain. For example, you might see it used to express that a property holds for all numbers, for all points in a set, or for all values within a defined range. In writing and documentation, “∀” can also appear in math education, proofs, and technical specifications. Because it’s a dedicated Unicode character, it works well for consistent rendering across fonts and platforms that support it.
Common uses
- •Writing formal logic statements like “for all x, …” in notes or documentation
- •Expressing universal rules in math problem solutions and proofs
- •Labeling or annotating constraints in formal specifications (e.g., “for all inputs …”)
- •Creating math or logic diagram text in slides, posters, and textbooks
- •Using as a typographic symbol in developer-facing documentation for specifications
