Embarking upon an exploration of growth models will entail using all of the arithmetic and algebraic skills you've obtained so far in the course. Exponents will play a large role in this module as will simplifying algebraic expressions, so please feel free to return to the Fractal module's review section as needed to refresh those ideas. But the focus of this review section is to extend the ideas of algebraic expressions into a study of equations. You've seen a few brief introductions to skills required to solve equations already. You built up the skill of rewriting expressions using the properties of real nubmers in the review section included in the Set Theory and Logic module, and the Voting Theory module's review section looked at equations of lines in the coordinate plane. Now, in preparation to study growth models, it's time to formally introduce the skill of solving equations.
