TypeScript Arithmetic Operators

Arithmetic operators in TypeScript are used to perform basic mathematical operations like addition, subtraction, multiplication, and division. These operators work with numbers to calculate results.

List of Arithmetic Operators

Examples of Arithmetic Operators

Addition (+)

Adds two numbers together.

let a = 5;
let b = 3;
let sum = a + b;
console.log(sum); // Output: 8

Subtraction (-)

Subtracts the second number from the first.

let a = 10;
let b = 4;
let difference = a - b;
console.log(difference); // Output: 6

Multiplication (*)

Multiplies two numbers.

let a = 6;
let b = 7;
let product = a * b;
console.log(product); // Output: 42

Division (/)

Divides the first number by the second.

let a = 20;
let b = 4;
let quotient = a / b;
console.log(quotient); // Output: 5

Modulus (%)

Returns the remainder of the division of two numbers.

let a = 10;
let b = 3;
let remainder = a % b;
console.log(remainder); // Output: 1

Increment (++)

Increases the value of a number by 1.

let a = 5;
a++;
console.log(a); // Output: 6

Decrement (--)

Decreases the value of a number by 1.

let a = 5;
a--;
console.log(a); // Output: 4

Summary

Arithmetic operators are essential for performing calculations in TypeScript. By understanding how to use them, you can write programs that handle numbers effectively and solve various mathematical problems.
