Math Operators

275 个字符

The full Mathematical Operators block (U+2200–U+22FF) plus the fundamental ASCII operators and selected letterlike symbols used in mathematical notation. Covers set theory (∈ ∉ ⊂ ⊃), logic (∧ ∨ ¬), calculus (∂ ∫ ∑ ∏), relational operators (≤ ≥ ≠ ≈), and dozens more. The authoritative reference for anyone working with mathematical typesetting, LaTeX, or scientific documentation.
