Calculator program in swift programming language to execute the calculations like addition, subtraction, multiplication and division in swift. These calculation process were done using the symbols like +,- etc.

## Operator in Swift

A particular symbol or phrase called an operator is used to inspect, alter, or combine information.

The addition operator ( + ) adds two numbers together, as in let I = 1 + 2, and the logical AND operator ( && ) combines two Boolean values, as in if enteredDoorCode && passedRetinaScan.

Operators are a subset of functions that take one or more arguments and return a new value.

Operators include things like addition (+), subtraction (-), multiplication (*), and so on. Variables and constants are operated on with the help of operators.

## Mathematical Operators in Swift

A mathematical function that performs a computation on two operands is known as an arithmetic operator.

They’re common in ordinary math, and most programming languages include a library of them that can be used in equations to do a variety of sequential calculations.

Addition, subtraction, multiplication, and division are the four basic arithmetic operations for real numbers.

The commutative, associative, and distributive characteristics are the fundamental arithmetic properties.
