Does Not Divide Symbol Meaning
The symbol ∤ (Unicode name: DOES NOT DIVIDE, code point U+2224) expresses that a number or quantity does not divide another without remainder. In divisibility statements, it’s paired with the “divides” relation: for example, you might write “a divides b” as a ∣ b, and “a does not divide b” as a ∤ b. It can also appear in proofs, checks, and number theory contexts to indicate that a division relationship fails. Outside of formal mathematics, it can be used in technical notes, worksheets, or explanations to convey “not divisible” with a compact symbol.
Common uses
- •Number theory and divisibility checks (e.g., stating non-divisibility)
- •Math homework and worksheets to write “does not divide” between two expressions
- •Proof writing where a divisibility condition must be negated
- •Technical documentation for constraints like “X does not divide Y”
- •Educational content and tutorials that emphasize contrasting symbols (∣ vs ∤)
