JavaScript Arithmetic Operators includes operators like Addition, Subtraction, Multiplication, Division and Modulus. All these operators are binary operators which means they operate on two operands. Below table shows the Arithmetic Operators in JavaScript with examples.
| JavaScript Arithmetic Operators | Operation | Example |
|---|---|---|
| + | Addition | 10 + 2 = 12 |
| – | Subtraction | 10 – 2 = 8 |
| * | Multiplication | 10 * 2 = 20 |
| / | Division | 10 / 2 = 5 |
| % | Modulus – It returns the remainder after the division | 10 % 2 = 0 (Here remainder is zero). If it is 10 % 3 then it will be 1. |
JavaScript Arithmetic Operators Example
For this example, We are using two variables a and b and their values are 12 and 3. We are going to use these two variables to perform various arithmetic operations present in JavaScript Programming Language
