# Operators

Docs are available before the release of Designer Cloud so you can get a sneak peek. This content might change between now and the official release.

An operator is a character that represents an action. Use an arithmetic operator to perform mathematical calculations or a Boolean operator to work with true/false values. Operators can be used with all data types.

### Block Comment

`/*Comment*/`: Use a block comment operator to add a comment block to an expression editor (within the expression line) without interfering with the expression.

### Single Line Comment

`// Comment`: Use the single line comment operator to add a single-line comment to an expression editor without interfering with the expression.

`Addition +`: Use the addition operator to add multiple numeric values together.

### Boolean Operators

`Boolean AND &&`: (Boolean AND) Use this operator to combines 2 Boolean values. The result is also a Boolean value. The result is True if both of the combined values are true, and the result is False if either of the combined values is false.

`Boolean AND - Keyword`: (Boolean AND) Use this operator to combines 2 Boolean values. The result is also a Boolean value. The result is True if both of the combined values are true, and the result is False if either of the combined values is false.

`Boolean NOT !`: (Boolean NOT) Accepts one input. If that input is true, it returns False. If that input is false, it returns True.

`Boolean NOT - Keyword`: (Boolean NOT) Accepts one input. If that input is true, it returns False. If that input is false, it returns True.

`Boolean OR - Keyword`: (Boolean OR) If either (or both) of the two values are true, it returns True.

`Boolean OR ||`: (Boolean OR) If either (or both) of the two values are true, it returns True.

### Close Parenthesis

`Close Parenthesis )`: Close Parenthesis

### Division

`Division /`: Use the division operator to divide a numeric value by another numeric value.

### Equal To

`Equal To =`: Equal To

### Greater Than Operators

`Greater Than >`: Greater Than

`Greater Than Or Equal >=`: Greater Than Or Equal To

### Less Than Operators

`Less Than <`: Less Than

`Less Than Or Equal <=`: Less Than Or Equal

### Multiplication

`Multiplication *`: Use the multiplication operator to multiply multiple numeric values together.

### Not Equal To

`Not Equal To !=`: Not Equal To

### Open Parenthesis

`Open Parenthesis (`: Open Parenthesis

### Subtraction

`Subtraction -`: Use the subtraction operator to subtract a numeric value from another.

### Value IN Operators

`value IN (...) - Keyword`: (Test Value in List) Determines if a given value matches any value in a subquery or a list.

`value NOT IN (...) - Keyword`: (Test Value Not in List) Determines if a given value matches any value not in a subquery or a list.
