How to calculate a due date based on a project deadline?

I have a tracker that completes the due date for each line item based on the final deadline through either adding or subtracting. Is there a way to do the same in Smartsheet.

Deadline 10.15.2022, Budget Development needs completed 270 in advance.

Excel formula | =10/15/2022 - 270 = 01/18/2022

Any help would be greatly appreciated.
