# Arithmetic and Relational Operator in typescript This tutorial explains Arithmetic and Relational Operator in typescript with examples.

## Typescript arithmetic operator

`Arithmetic operators` are used in expressions with two or more entries.

This operator will work on numeric values.

These operators are very easy to understand as these are available in our study curriculums as well as other programming languages.

This evaluates `Arithmetic operators` on two operands.

Here is a syntax

``operand1 operator operand2``

Assume that p has a value of 20, and q has a value of 30.

OperatorTitleDescriptionExample
`+`Additionreturn values which are computed addition of two or more values`p+q=50`
`-`Subtractionreturn values which are computed subtraction of two or more values`q-p=10`
`*`Multiplicationreturn values which are computed multiplication of two or more values`p*q=600`
`/`DivideCalculate the division of values`q/p=1.5`
`%`ModulusReturn the remainder after the division of values`q%p=10`
`++`IncrementIncrement the value by 1`++p=21`
`--`DecrementDecrement the value by 1`--q=29`

## arithmetic operator Example

Here is an arithmetic operator example

``````var m = 50;
var n = 20;
console.log(m + n); // returns 70
console.log(m - n); // returns 30
console.log(m * n); // returns 1000
console.log(m / n); // returns 2.5
console.log(m % n); // returns 10
console.log(++m); // returns 51
console.log(--n); // returns 19``````

## Relational Operators in typescript

The `Relational` operator returns `true` or `false` to check operands.

Assume values of M are 10 and N is 20.

OperatorTitleExample
`<`Less than`M<N` is false
`>`Greater than`M>N` returns false
`<=`Less than equal`M<=N` returns false
`>=`Greater than equal`M>=N` returns false

Following is a Relational Operator Example

``````var m = 50;
var n = 20;
console.log(mn); // returns true
console.log(m <= n); // returns false
console.log(m >= n); // returns true``````

## Typescript Equality Operators

These operators check the equality of operands.

assume values of C are 10 and D is 20

OperatorTitleDescriptionExample
`==`Equalityreturns boolean, first check if types are equal, then compare the values of types are objects, then compares references of the same objects if types are not equal, then it will apply strict comparison`M==N` returns false
`!=`Not equalIt will also do the same logic as the above operator with not equal check`M!=N` returns true
`===`Identity OperatorThis will checks strict equality without doing type conversion`M!=N` returns true
`!==`Non IdentityThis will check non-strict equality without checking the same types`M!=N` returns true
