h ≠ d² - Mathematical Inequality Symbol Explained #2257607 (License: Personal Use)

This image displays a clean, high-contrast rendering of the mathematical inequality h ≠ d², using standard italic serif typography typical of typeset mathematics. The symbol ≠ (not equal) emphasizes a strict distinction between two quantities, often used in derivations, proofs, or problem constraints where equality must be explicitly excluded. The notation appears frequently in algebraic reasoning, geometric modeling, and theoretical physics.

Used in educational content, math textbooks, online courses, or technical documentation to illustrate inequality constraints; matches user intent for understanding symbolic notation or verifying equation conditions.
