Like GLU Functions, GLU Formulas are versatile tools for derived parameters, request, and response handlers.

**Note**: FORMULAs involve mathematical calculations and are always prefixed with the ‘=’ symbol. FUNCTIONs are not preceded by any symbol.

**Addition Formula**

The Addition Formula is implemented as follows:

`=${amountOne}+${amountTwo}+${amountThree}+...` |

This formula performs the summation of a set of values (Integer or Float). When utilised in a Derived Parameter, it returns the SUM of the specified values.

**Example**

`formulaSum =${amountOne}+${amountTwo}+${amountThree}` |

Given:

- `amountOne = 2`
- `amountTwo = 3`
- `amountThree = 5`

The result is:

- `formulaSum = 10`

This shows that the `formulaSum` Derived Parameter returns the product of the values assigned to `amountOne`, `amountTwo`, and `amountThree`. In the provided example, the SUM yields a value of 10.

**Multiplication Formula**

The Multiplication Formula is implemented as follows:

`=${amountOne}*${amountTwo}*${amountThree}*…` |

This formula serves the purpose of multiplying a set of values, whether they are integers or floats. When utilised in the creation of a Derived Parameter, it yields the PRODUCT of the specified values.

**Example**

`formulaMultiply =${amountOne}*${amountTwo}*${amount Three}` |

Given:

- `amountOne = 2`
- `amountTwo = 3`
- `amountThree = 5`

The result is:

- formulaMultiply = 30

This shows that the formulaMultiply Derived Parameter returns the product of the values assigned to `amountOne`, `amountTwo`, and `amount Three`. In the provided example, the multiplication yields a value of 30.

# Division Formula

The Division Formula is implemented as follows:

`=${amountOne}/${amountTwo}` |

This formula is designed to divide one value, whether it is an integer or float, by another. When employed in the creation of a Derived Parameter, it yields the QUOTIENT of the specified values.

**Example**

`formulaDivide =${amountOne}/${amountTwo} ` |

Given:

- `amountOne = 550`
- `amountTwo = 100`

The result is:

- formulaDivide = 5.5

In this example, the formulaDivide Derived Parameter produces the outcome of dividing the value of `amountOne` by the value of `amountTwo`, resulting in a quotient of 5.5.
