Write Get-ArraySum so it returns the sum of the integers in -Numbers.

An empty array sums to 0.

    Get-ArraySum -Numbers 1, 2, 3   # 6

    Get-ArraySum -Numbers @()       # 0

'@

        'Start an accumulator at 0 and add each number with a foreach loop.'

        'Or let the pipeline do it: ($Numbers | Measure-Object -Sum).Sum. Check what that returns for an empty array.'
