≢

not identical to

Not Identical To

≢ denies the relation marked by ≡: depending on the field, that can mean not identical, not equivalent, or not congruent. In modular arithmetic, it says two numbers leave different remainders when divided by the same fixed number. For ordinary inequality, use ≠.

What ≢ means

It denies whichever triple-bar relation the formula uses.

That relation can mean identity, equivalence, or congruence. In modular arithmetic, congruent numbers leave the same remainder when divided by a fixed number; ≢ says the remainders differ.

Triple-bar notation developed alongside formal equality notation. The modern equal sign appeared in print in 1557; Gauss used a triple bar for modular congruence from 1801.

Formal mathematical notation; use it in a formula or explain the convention in prose.

Use ≠ for ordinary inequality; ≢ rejects a field-specific relation marked by a triple bar.

Don't confuse it with

≠

Not Equal To

≢ vs ≠: ≢ denies the field-specific triple-bar relation; ≠ says only that the two values are unequal.

Questions people ask

Why does ≢ show as a box on some devices?

Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
