**Operator Nodes**

Operator Nodes refer to mathematical concepts that are applied within a scenario. There are two Operator Node sub-categories:

**Equals**: Performs a comparison to validate is two items are equal to one another.

**Mathematical Nodes**

Mathematical Operator Nodes apply mathematical calculations and operations to impact the Scenario.

**Subtraction**: Calculates the difference between the minuend and subtrahend.**Addition**: Calculates the sum of two addends.**Division**: Calculates the quotient by dividing the dividend by the divisor.**Multiplication**: Calculates the product by multiplying two factors.**Approximation**: Validates if a number is approximate to another value.**Exponentiation**: Calculates the power of the base to the exponent.

**Logic Gates**

Logic Gates represent basic building blocks within digital circuits. Most Logic Gates have two inputs along with one output, and are based on Boolean Algebra. These Logic Gates behave according to a truth table.

**Or Gate**: The output of the Or Gate is at logic 1 when one or more are at logic 1. If all inputs are at logic 0, the output is at logic 0. See the descriptive truth table below:

**And Gate**: The output of the And Gate is at logic 1, when all of its inputs are at logic 1. Otherwise, the output is at logic 0. See the descriptive truth table below:

**Not Gate**: The output of the Not Gate is at logic 0 when its only input is at logic 1, and at logic 1. when its only input is at logic 0. It's often referred to as an inverter. See the descriptive truth table below:

**Xor Gate**: The output of the Xor Gate is at logic 1 when one and only one of its inputs is at logic 1. Otherwise, it's at logic 0. See the descriptive truth table below:
