# Math
Math blocks provide numerical operations and calculations for your scripts. Use these blocks to perform arithmetic, apply mathematical functions, and manipulate numeric values from sensors or variables.
## value
A numeric constant. Use this block to provide fixed numbers for calculations, comparisons, or as parameters to other blocks.
**Parameters:**
* **Value** (Number): Enter any numeric value (integers or decimals)
**Example:**
Define temperature thresholds
## math operation
Applies a single-value mathematical operation. Choose from absolute value (removes sign) or negation (flips positive to negative and vice versa).
**Parameters:**
* **Operation**: Select `abs` (absolute value) or `-` (negate)
* **Value** (Number): The number to operate on
**Returns:**
* **Number**: The result of the operation
**Example:**
Temperature difference calculation
## arithmetic
Performs basic arithmetic operations between two numbers.
**Parameters:**
* **Left Value** (Number): The first number
* **Operator**: Choose `+` (add), `-` (subtract), `×` (multiply), `÷` (divide), `^` (power)
* **Right Value** (Number): The second number
**Returns:**
* **Number**: The result of the calculation
**Example:**
Convert raw sensor value to voltage
## number condition
Checks whether a number meets a specific condition. Use this for pattern detection or periodic actions.
**Parameters:**
* **Value** (Number): The number to check
* **Condition**: Select `even`, `odd`, `positive`, `negative`, `whole`, `divisible by`
**Returns:**
* **Boolean**: `#t` (true) if the condition is met, `()` (false) otherwise
**Example:**
Read sensor value every 5th script execution
## remainder
Calculates the remainder after dividing one number by another (modulo operation). Useful for creating repeating patterns or detecting multiples.
**Parameters:**
* **Dividend** (Number): The number to be divided
* **Divisor** (Number): The number to divide by
**Returns:**
* **Number**: The remainder of the division
**Example:**
