Convert a handicap index into a course handicap using slope and rating.
The slope rating scales a handicap index to the course difficulty, and 113 is the neutral value. Harder courses give more strokes, which is what makes handicaps portable between courses. Playing a high-slope course from an unadjusted index systematically disadvantages higher handicappers, which is precisely what the adjustment exists to correct.

Course handicap = index × slope ÷ 113 + (course rating − par)
