The company produced the iconic "Problem Solver" series of comprehensive solution guides. The Problem Solver series eventually encompassed over 30 topics with more than 28,000 problem/solution sets, covering differential equations, electric circuits, electronic circuits, precalculus, calculus, advanced calculus, algebra and trigonometry, physics, linear algebra, statistics, organic chemistry, mechanics, thermodynamics, electromagnetics, geometry, chemistry, probability, materials strength, heat transfer, economics, robotics, discrete math, fluid mechanics and dynamics, numerical analysis, optics, topology, electronic communications, operations research, and several others.
