Arithmetic operators allow us to perform mathematical calculations such as adding, subtracting, multiplying, and dividing numerical values.
The basic arithmetic operators are:
| Operator | Name | Description |
|---|---|---|
+ | Addition | Adds two values |
- | Subtraction | Subtracts the second value from the first |
* | Multiplication | Multiplies two values |
/ | Division | Divides the first value by the second |
% | Modulus | Returns the remainder of the division of the first value by the second |
** | Exponentiation | Raises the first value to the power of the second |
++ | Increment | Increases the value of a variable by one |
-- | Decrement | Decreases the value of a variable by one |

List of Arithmetic Operators
Addition (+)
The addition operator is used to add two values.
let result = 10 + 5; // result is 15Subtraction (-)
The subtraction operator is used to subtract one value from another.
let result = 10 - 5; // result is 5Multiplication (*)
The multiplication operator is used to multiply two values.
let result = 10 * 5; // result is 50Division (/)
The division operator is used to divide one value by another.
let result = 10 / 5; // result is 2Exponentiation (**)
The exponentiation operator raises the first operand to the power of the second operand. It is useful for more advanced mathematical calculations and operations involving powers.
let result = 2 ** 3; // result is 8, which is 2 raised to 3Modulus (%)
The modulus operator returns the remainder of a division.
let result = 10 % 3; // result is 1, because 10 divided by 3 is 3 with a remainder of 1Increment (++)
The increment operator increases the value of a variable by 1.
let number = 5;
number++; // Now number is 6Decrement (—)
The decrement operator decreases the value of a variable by 1.
let number = 5;
number--; // Now number is 4
