Basic Math/Arithmetic Operators in Kotlin

Operators constitute the basic building block to any programming language. Java too provides many types of operators which can be used according to the need to perform various calculation and functions be it logical, arithmetic, relational etc. They are classified based on the functionality they provide. Here are a few types:

An operator is a special symbol which indicates a certain process is carried out. Operators in programming languages are taken from mathematics. Programmers work with data. The operators are used to process data. An operand is one of the inputs (arguments) of an operator.

Expressions are constructed from operands and operators. The operators of an expression indicate which operations to apply to the operands. The order of evaluation of operators in an expression is determined by the precedence and associativity of the operators.

Arithmetic Operators Unary Operators Assignment Operator Relational Operators Logical Operators Ternary Operator Bitwise Operators Shift Operators

Operators works on operands and used for calculation. For example, + is an operator and when I use it in a expression like this: a+b, it performs addition on operands a & b. In this guide, we will learn types of operators available in Kotlin and how to use them.

Certain operators may be used in different contexts. For instance the + operator can be used in different cases: it adds numbers, concatenates strings, or indicates the sign of a number. We say that the operator is overloaded.
