Separate commands in a script block

Question

Consider this simple code:

$myObject = New-Object PSCustomObject
$myObject | Add-Member -MemberType ScriptMethod -Name 'Multiply' -Value { $x=Read-Host; $x = $x * 10; Write-Host "$x" } 
$myObject.Multiply()

Entering 1 returns 1111111111 but I would expect the value to be 10.

What is wrong?

Thats because $x is a string as you can verify by calling $x.GetType():

IsPublic IsSerial Name                                     BaseType
-------- -------- ----                                     --------
True     True     String                                   System.Object

You can fix that by casting the variable to a [double]:

$x=Read-Host; $x = [double]$x * 10; Write-Host "$x"
