An artist’s lawbreaking pastime, whereby they irreverently
paint math-related drawings, formulas, or symbols in forbidden areas or public squares without getting caught by the authorities—the artistic equivalent of a
couple illicitly indulging in a quickie with zero public knowledge or suspicion.

illegal activities give the mathematical
graffiti artist more thrill when working in a pressurized environment, compared to taking part in an annual pressure-free
graffiti carnival approved by the authorities.
