C# Operators
Operators
Operators are used to perform operations on variables and values.
In the example below, we use the
+
operator to add together two values:
Although the +
operator is often used to add together two values, like in the example above, it can also be used to add together a variable and a value, or a variable and another variable:
Example
int sum1 = 100 + 50; // 150 (100 + 50)
int sum2 = sum1 + 250; // 400 (150 + 250)
int sum3 = sum2 + sum2; // 800 (400 + 400)
Arithmetic Operators
Arithmetic operators are used to perform common mathematical operations:
Operator | Name | Description | Example | Try it |
---|---|---|---|---|
+ | Addition | Adds together two values | x + y | Try it » |
- | Subtraction | Subtracts one value from another | x - y | Try it » |
* | Multiplication | Multiplies two values | x * y | Try it » |
/ | Division | Divides one value by another | x / y | Try it » |
% | Modulus | Returns the division remainder | x % y | Try it » |
++ | Increment | Increases the value of a variable by 1 | x++ | Try it » |
-- | Decrement | Decreases the value of a variable by 1 | x-- | Try it » |
