From the mirror the distances must be measured.
Distances measured in the direction of incidence of light must be evaluated as positive and in the opposite direction of incidence of light as negative.
Object height and image height are positive when measured from the axis up and negative when measured down.
Focal length and radius of curvature are negative for a concave mirror and positive for a convex mirror.
