A "scandalous number" typically refers to a number that has unusual or interesting properties, often used in recreational mathematics. One well-known example is the number 4, which can be considered scandalous in some contexts due to its ties to various mathematical curiosities, such as being the smallest composite number and the only even number that is not a prime.
In a different context, the term might refer to a number that is associated with a particular event or person that has a negative connotation, such as a number linked to a scandal in popular culture.
