This text investigates the foundational mathematical concepts required for calculus while integrating the practical use of electronic calculators as a primary computational tool. Joseph Elich provides a structured approach to precalculus, focusing on the transition from algebraic manipulation to functional analysis. The book utilizes a pedagogical framework that emphasizes the synergy between theoretical understanding and the mechanical efficiency provided by modern calculating devices.

Educators often cite this work as a functional resource for students transitioning into higher-level mathematics. The text is noted for its straightforward approach to integrating technology into traditional curriculum standards.
