Obtain total amount of days to close a claim (SmartSheets)

I would like to be able to find out how many days it has taken to close a claim. I cannot figure out the formula to do this. Is there a formula that I may use to cop and paste all the way down my rows?

Each column are calendar dates.

Date of Loss Date Closed Total days

01/20/2020 8/30/2020 =

Can someone please help?
