This document introduces a mathematics course covering numeric sets. It includes: - The structure of the course which is divided into 5 units covering numeric sets, algebraic expressions, factoring, radicals, and equations. - The first unit covers numeric sets, including defining sets, classifying sets, and basic operations on sets of rational and real numbers. It provides examples of set definitions and operations. - Sample problems are given to apply concepts of simplifying expressions with grouping symbols and performing operations on fractions. The steps to solve these problems are shown. - Reflection questions at the end ask students to recall concepts from set theory and how to solve algebraic fractions and expressions with grouping symbols.
