Intersection is a formal mathematical operator or relation symbol used in academic and technical writing — algebra, calculus, logic, or set theory — to express a precise mathematical relationship concisely.
Unicode block: Mathematical Operators (U+2200–U+22FF). This large block standardizes the symbols used across algebra, calculus, logic, and set theory, replacing the inconsistent, often hand-drawn notation used before digital typesetting.
At Unicode code point U+2229 (decimal 8745), Intersection is the 42nd of 256 characters cataloged in this category on How To Type Any Symbol. In terms of typing methods, it has a documented Windows Alt code, though no dedicated single-key Mac shortcut — Mac users generally rely on copy-paste for it. Regardless of platform, clicking the copy button above places the exact character on your clipboard, ready to paste into any application that accepts Unicode text.
💡 Good to know: Screen readers often mispronounce or skip mathematical symbols — accessible math content typically needs MathML or alt-text descriptions alongside the raw character.
