Distributivity

Definition

Distributivity is a property that describes how operations interact with each other, particularly in the context of addition and multiplication. In mathematical terms, it asserts that for any three elements A, B, and C, the operation can be distributed over another, such that A * (B + C) = A * B + A * C. This concept is vital in fuzzy set theory as it helps understand how different fuzzy operations can be combined and manipulated to achieve desired results.
