distributive

Mathematics
  • Suppose that ∘ and * are binary operations on a set S. Then ∘ is distributive over * if, for all a, b, and c in S,

    a(b*c)=(ab)*(ac) , (a*b)c=(ac)*(bc)

    If the two operations are multiplication and addition, ‘the distributive laws’ normally means those that say that multiplication is distributive over addition.
