Equality and Comparison Signs

The set for formulas you would otherwise fake with punctuation. Not-equal (≠) is a single character, not "=" with a slash over it, so it never breaks across a line. Identical (≡) is stronger than equality: it holds for every value. Approximately (≈) marks rounding, plus-minus (±) states a tolerance, and ≤ and ≥ spare you the ASCII "<=" pair.

≠ Not Equal To ≈ Approximately Equal To ≤ Less Than or Equal To ≥ Greater Than or Equal To ± Plus Minus Sign ≡ Identical To
