Now add **two numeric fields** ( "Number One" and "Number Two"). Then, add a **third numeric field** to display the calculation result ("Result").

## Enable Calculation Expression

Now hover over the **Result** field (where you want to show the result) and click the **Edit (pencil) Icon**. In the right sidebar, go to **Advanced Options**.

Now, click on the **Enable Calculation option** from the **Advanced Option** to activate the calculation box.

## Define the Calculation

Now, click on the **Document Icon**, and it will show all the available input fields.

Select the numeric fields to be used in the calculation ( Number One, Number Two).

 Now add a mathematical operator between them ( +, -, *, /).

- Example: Number One + Number Two

> Avoid spaces between fields and operators. For a better understanding, see the screenshot below.

## Embed the Form into the Front

Once you complete the customization, click the **Save** **Form** button to save all your changes. Click the **Preview & Design**buttonin the middle to see the form preview.

To integrate and display the form on a specific Page or post, **copy** the **Shortcode** from the top right side and **paste** it into your desired **Page or post**.

### Conversational Forms Support

Fluent Forms also supports calculations in **Conversational Forms**, enabling dynamic responses based on user input.

**Example**

If you have an order form where a user selects the number of items, you can calculate the total price dynamically:
Quantity * Price Per Item = Total Price
