Expression Builder Problem

Need help
1

I’m having trouble with the expression builder in a search constraint. I need to basically implement, on the end of a date, +days: (1 - Current Date/Time:extract day)

I know how to do the extract piece, but I just can’t figure out how to enter the part in parenthesis in the expression builder.

I figured it out by enabling the parenthesis function in settings so that I could control the order of operations in the expression.
