# Memory Support

The **Calculator** component supports all native memory functionality the end user is accustomed with.

The following list shows the supported memory actions with example.

* **Memory Plus (M+)**—Adds the current input into the memory.

  Example:

  1. Input - '3' -> M+ -> Memory Value - '3'
  2. Input - '6' -> M+ -> Memory Value - '9'

* **Memory Minus (M-)**—Substracts the current input value from the memory value.

  Example:

  1. Input - '5' -> M- -> Memory Value - '-5'
  2. Input - '6' -> M- -> Memory Value - '-11'

* **Memory Store (MS)**—Stores the current input value into the memory. For example:

  Example:

  1. Input - '42' -> MS -> Memory Value - '42'
  2. Input - '82' -> MS -> Memory Value - '82'

* **Memory Recall (MR)**—Displays the value stored into the memory.

  Example:

  1. Input - '42' -> MR -> Memory Value - '42'
  2. MR -> Displayed Value - '42'

* **Memory Clear (MC)**—Clears the memory value.

The current memory value can be assigned manually by setting the `MemoryValue` property.

#### **Setting the memory value manually**

```XAML
<telerikControls:RadCalculator MemoryValue="2"/>
```

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

## Hiding the Memory Buttons

To hide the buttons, set the `MemoryButtonsVisibility` property of `RadCalculator` or `RadCalculatorPicker` to `Collapsed`.

#### **Hiding the memory buttons**

```XAML
<telerikControls:RadCalculator MemoryButtonsVisibility="Collapsed"/>
```
