distributive law
distributive law: In mathematics, given any two operations, symbolized by * and ∘, the first operation, *, is distributive over the second, ∘, if a*(b∘c)=(a*b)∘(a*c) for all possible choices of a, b, and c. Multiplication, ×, is distributive over addition, +, since for any numbers a, b, and c, a×(b+c)=(a×b)+(a×c). For example, for the numbers 2, 3, and 4, 2×(3+4)=14 and (2×3)+(2×4)=14, meaning that 2×(3+4)=(2×3)+(2×4). Strictly speaking, this law expresses only left distributivity, i.e., a is distributed from the left side of (b+c); the corresponding definition for right distributivity is (a+b)×c=(a×c)+(b×c).

distributive law
distributive law Rule of combination in mathematics, in which an operation applied to a combination of terms is equal to the combination of the operation applied to each individual term. Thus, in arithmetic 3 × (2 + 1) = (3 × 2)+(3 × 1) and, in algebra a(x + y) = ax + ay.
