     Executes mathematical expressions via Windows 10 Calculator with error handling.
     .DESCRIPTION
     Uses calc.exe /f to compute expressions and validates results.
     Supports basic arithmetic, parentheses, and functions like sqrt().
     .PARAMETER Expression
     The mathematical expression to evaluate (e.g., "(10 + 20) 0.5").
     .EXAMPLE
     .\Calculate.ps1 -Expression "(100 / 3) 2"
     #> param (
     [Parameter(Mandatory=$true)]
     [string]$Expression
     )

     # Validate input for allowed characters (basic arithmetic + parentheses)
     if ($Expression -match '[^0-9+\-*/().\s]') {
     Write-Error "Unsupported character in expression: '$Expression'. Use only +, -, *, /, (), ., and digits."
     exit 1
     }

     # Execute calculation via calc.exe and capture output
     try {
     $result = calc.exe /f "$Expression" | Select-String -Pattern '\d+\.?\d*' -ErrorAction Stop
     if (-not $result) {
     throw "Calculator returned no numeric result. Check expression syntax."
     }
     $output = $result.Matches.Value
     Write-Host "Result: $output"
     

     Optional: Output to clipboard

     $output | clip
     } catch {
     Write-Error "Calculation failed: $_"
     exit 1
     }
     

     Key Features of the Script:
