# Javascript arithmetic operators tutorial

## JavaScript Arithmetic Operators:

Arithmetic operators are used to perform arithmetic operations.

## JavaScript Arithmetic Operators List:

 Operator Description Example + Addition 30+20 = 50 – Subtraction 30-10 = 20 * Multiplication 10*10 = 100 / Division 50/10 = 5 % Modulus (Remainder) 50%7 = 1 ++ Increment var a=10; a++; Result into a = 11 — Decrement var a=10; a–; Result into a = 9

## JavaScript Arithmetic Operators Example:

```<html> <head> <script type="text/javascript"> var a = 33; var b = 10; var c = "Test"; var linebreak = "<br />";   document.write("a + b = "); result = a + b; document.write(result); document.write(linebreak);   document.write("a - b = "); result = a - b; document.write(result); document.write(linebreak);   document.write("a / b = "); result = a / b; document.write(result); document.write(linebreak);   document.write("a % b = "); result = a % b; document.write(result); document.write(linebreak);   document.write("a + b + c = "); result = a + b + c; document.write(result); document.write(linebreak);   a = ++a; document.write("++a = "); result = ++a; document.write(result); document.write(linebreak);   b = --b; document.write("--b = "); result = --b; document.write(result); document.write(linebreak); </script> </head> <body> </body> </html>```
