title: Adding up numbers in PowerShell
body: <p>I am trying to add up two numbers in PowerShell. I have the input the user gives stored in <code>$Value1</code> and <code>$Value2</code>. However I can't find any way to actually add these numbers up. I tried using the <code>Measure-Object</code> cmdlet but I can't seem to get it to work.</p>
  
  <p>How does one add up/substract and multiply numbers in Powershell?</p>
