# Getting Started with WinUI Calculator

This tutorial will walk your through the creation of a sample application that contains `RadCalculator`.

## Assembly References

In order to use `RadCalculator` in your projects, you have to add reference to the following assemblies:

* `Telerik.Windows.Controls.dll`
* `Telerik.Licensing.Runtime.dll`

## Adding RadCalculator to the Project

#### **Defining RadCalculator**

```XAML
<telerik:RadCalculator />		
```

The `telerikControls` namespace points to `xmlns:telerikControls="using:Telerik.UI.Xaml.Controls"`.

#### **RadCalculator example**

The calculated value can be accessed via the `Value` property of `RadCalculator`.

The current history can be accessed via the `History` property of `RadCalculator`.

## Performing Calculations

`RadCalculator` allows you to perform all the basic calculations - **addition, subtraction, multiplication, division**. All of them can be executed either by the corresponding buttons or through the keyboard. Once a particular operation is executed, the history is updated accordingly.
