Answer 1

There is a few ways to do this.

• Hold down the Alt key then type 0177 on the numpad and let go of Alt , this will cause you to type ±.

• Open up the program charmap in windows, find the character you are looking for, then click the "Select" then the "Copy" button. You will then be able to paste the ± character in your code.

• Copy the ± character from this question into your code.

   <Button x:Name="buttonPlusOrMinus" Content="±" HorizontalAlignment="Left" Margin="180,217,0,0" Grid.Row="2" VerticalAlignment="Top"/>
