in mathematics, an operation is a function which takes zero or more input values, called operands or arguments, to a defined output value
the number of operands is known as the arity of the operation
operations with an arity of 2 are called binary operations
binary operations include
- addition
- multiplication
operations with an arity of 1 are called unary operations
unary operations include
- additive inverse, also known as negation and sign change
- multiplicative inverse, also known as reciprocal
