Lesson Summary:

In this lesson, students review writing algebraic expressions from word statements, properties of real numbers, and solving equations for a variable. The three main steps for solving equations are simplifying, isolating the variable, and solving the equation. The properties of real numbers discussed include the reflexive, symmetric, and transitive properties. Additionally, a shortcut for dealing with fractions in fractions is provided, where the bottom fraction is put on top and flipped.
