I would like to assign a math operator (+ - / *) to a variable to build dynamic expressions.

For example:

$operator1 = [char][byte]'043'
$operator2 = [char][byte]'045'
$calculation = [int](1 $operator1 20 $operator1 30 $operator1 100 $operator2 51)
Write-Host calculation

The output 100

Remembering that the variable $calculation is extensive and contains more numbers.

You can do this with Invoke-Expression, but please remember that this is potentially dangerous

$operator1 = [char][byte]'043'
$operator2 = [char][byte]'045'

$calculation = Invoke-Expression -command "[int](1 $operator1 20 $operator1 30 $operator1 100 $operator2 51)"
Write-Host $calculation

Outputs 100
