Not Equal Symbol (≠) - Mathematical Inequality Icon #857 (License: Personal Use)

This high-contrast graphic displays the universal “not equal to” symbol (≠), composed of two parallel horizontal bars crossed by a diagonal slash. The symbol is filled in vivid red with a thin blue outline, set against a pure black background for maximum legibility and visual impact. Designed for digital use, it conveys logical inequality clearly in educational, technical, or UI contexts.

Used in mathematics education materials, coding documentation, software interfaces, and data visualization to indicate inequality. Matches user intent for symbolic representation of ≠ in web content, presentations, or icon libraries.
