Subtracting Days from a Due Date

Hello,
I need a formula that subtracts # of days (using a NUMBER) column from a Date (DATE column) to get a final DATE column. And I need it to use workdays not calendar days.

This doesn’t cover work days, only calendar days. Using a ‘negative’ will work with the automation.

Thanks, I have a formula for this but I need it to factor workdays.
