Op amp saturation.
However, the solution (and similar solutions) uses a negative saturation voltage (-12 [v]) instead of the positive value as drawn in the OP-AMP circuit - resulting in (-6 [v]) as opposed to (+6 [v]). Am I misunderstanding sign conventions, or the fundamental application of supply voltages?
