Introduction

This “Guide to Precalculus Review” is a  problem solving practice meant to support  students in  their understanding of some basic mathematical tools.

The Guide covers some Basic Algebra, Equations and inequalities,   Analytic geometry, and Functions. 

The readers are guided in each section through a summary of the main  notations, definitions, or rules of calculation, then a short video that explains the concepts and illustrates them by solving examples step by step. The readers can rework these examples before solving new suggested questions and then look at the feedback to assess their understanding. 

This approach aims to foster conceptual understanding and technical skills.

This review package can be used for a general review  while preparing for an advanced Calculus course.  It can be used for reworking a specific concept and get a focused review.
