For example, addition is a binary operation: 3 + 4 = 7 {\displaystyle 3+4=7} . A binary operation is an operation of arity two. Some definitions require the two inputs and the output to be elements of the same set. Binary operations are usually written using infix notation such as a ⋆ b {\displaystyle a\star b} rather than by functional notation of the form f ( a , b ) {\displaystyle f(a,b)} . Multiplication and exponentiation are frequently written without operator, but with exponents as superscript. In abstract algebra, a binary operation on a set S {\displaystyle S}...
