What degree should a staircase be?

Mark your measurements on 2′ x 12′ stringers with a framing square. Mark the rise and run (7.11″ and 10″, respectively) beginning from the top of the stringer. The notches cut out with a circular saw from the first stringer can be used as a pattern for subsequent stringers.
