Discrete math is surprisingly useful for product management. Many of the mental models from discrete math directly support better decision-making and system thinking.

Boolean logic, truth tables: Product logic, feature toggles.

Sets and set operations: User roles, feature access, targeting segments.

Combinatorics: Feature combinations, testing, pricing plans.

Probability: A/B testing, forecasting, risk modeling.

Finite state machines: User states, session management, error handling, mapping user journeys, mapping edge cases.
