Question

1. Define a binary operation on a set.​

Answer 1

Step-by-step explanation:

In mathematics, a binary operation or dyadic operation is a calculation that combines two elements to produce another element. More formally, a binary operation is an operation of arity two. More specifically, a binary operation on a set is an operation whose two domains and the codomain are the same set

Answer 2

Answer:

A binary operation can be considered as a function whose input is two elements of the same set S and whose output also is an element of S. ... As (a,b) is an element of the Cartesian product S×S S × S we specify a binary operation as a function from S×S S × S to S.
