# Math Operations

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

You can use this Action Step to perform mathematical calculations. You can enter a formula with
fixed values or add values using mapped variables. The result can be reused in the course of the
workflow.

The following mathematical operations are available:

- Addition

- Subtraction

- Multiplication

- Division

- Absolute value

- Maximum value

- Minimum value

- Exponentiation

- Round value

## Properties

**Calculate Expression Result as** Here, you can specify whether the result should be calculated and
displayed as a whole number (integer) or as a number with decimals (floating point/double-precision
floating point).

**Math Expression** The formula entered is shown here.

## Inbound Variables

**Math Expression** Here, you can enter a formula with fixed values (for example (42+84)/3), or
insert variables via _Insert Available Variables_ for use in performing the mathematical operations
(for example, ({a}+{b})/{c}).

## Outbound Variables

**ResultAsFloat** The result is displayed as a floating-point value.

**ResultAsInt** The result is displayed as a whole number (integer).

## Wizard

Enter the formula in the _Math Expression_ text field. Clicking _Insert Mathematical Operation_
opens a drop-down list with all available mathematical operations.

Under _Insert Available Variables,_ you will find all variables previously added using the Pin
button.

Up to ten variables can be mapped. These are displayed in the Wizard and can be selected for the
calculation.

You can enter test values in the _Test Values_ field to test whether or not the formula is valid.
Then click the _Test_ button. If the formula is valid, the result will be displayed. Otherwise, an
error message will appear. The values of the mapped variables are not important until the production
run of the workflow.

If you want to output the result as a floating-point value, select _Calculate Expression Result as
Floating-Point Value_; if you want to display the result as a whole number, select _Calculate
Expression as Integer Value_.

Please note that implied multiplication also applies when you enter the _Math Expression_ and you
must put in the parentheses yourself.
