Explaining the Logic of Zero Outcomes in Professional Metrics

In professional data analysis, a 'Total Impact' score is often calculated by multiplying two factors, such as 'Frequency' and 'Severity'. If the Total Impact is 0, you must use a specific mathematical property to conclude that either the Frequency or the Severity must be 0. State the name of this property, provide its formal mathematical definition (using variables like aa and bb), and briefly explain the logic of why a product of two quantities can only equal zero if at least one of those quantities is zero.
