### Chapter 1: Algebraic Expressions and Operations with Real Numbers

This chapter is a comprehensive tour through the basic operations of real numbers and the foundations of algebraic expressions. You will begin with learning about variables and how to translate to and from words and algebraic expressions. From there, a healthy dose of the order of operations (PEMDAS) and plugging numbers into expressions involving variables is your next stop. You will then rock square roots of perfect squares and classify and study the properties of real numbers. Then comes the core part of the chapter where you will review all forms of adding, subtracting, multiplying, and dividing integers, decimals, and fractions.

Set? Go start learning the foundations of functions!!!!

### Chapter 6: Linear Functions and Graphing Lines

This chapter is one of the core branches of Algebra 1. Your journey through lines begins with a super thorough tour of rate of change and slope along with direct variation. From there you will learn the three forms of a linear function: slope-intercept form, point-slope form, and standard form. In your explorations of these three forms, you will learn to graph, construct, and use these linear functions in various scenarios. You will then rock horizontal and vertical lines followed by mastering the ins and outs of parallel and perpendicular lines. The chapter finishes off with a study of scatterplots and the all-important graphing of absolute value functions to understand how graphs are shifted in all directions. Let’s start up this linear awesomeness!!!

### Chapter 7: Systems of Linear Equations and Linear Inequalities

This chapter kicks off with learning what systems of linear equations are and how they can be represented and solved by graphing. You will then shuttle over to learning the two core methods for solving systems of linear equations: substitution and elimination. From here you will learn how to translate word problems into systems of linear equations in order to solve the word problems. The last several sections of the chapter will have you learning how to graph linear inequalities and systems of inequalities before finishing up with a lesson on linear inequality word problems. Go see just how great you can be at systems!!

### Chapter 8: Exponent Rules & Exponential Functions

This chapter takes you on a math excursion through all the rules of exponents and provides an introduction into exponential functions. You will begin with the rules for multiplying powers with the same bases and raising a power to a power. From there, you will master how to divide powers with the same bases. Then it is off to zero and negative exponents before rocking multiple practice exercises involving several rules in each problem – awesome practice found there! You will master simplifying operations involving scientific notation. The chapter finishes with a flurry of learning about exponential growth and decay, graphing exponential functions, calculating compound interest, and last, but not least, geometric sequences. Yeah…it is a pretty sweet chapter!!! Now go get math-ing!!!

### Chapter 9: Polynomials

Welcome to a major bridge between Algebra 1 and Algebra 2! This chapter begins with an introduction to what monomials and polynomials are and how to name them. You will then learn to add and subtract polynomials like a pro. From there you will master how to multiply polynomials, starting with the product of a monomial and a polynomial before rocking the FOIL method to multiply two binomials. A nice lesson on polynomial word problems follows and then it is off to factoring out greatest common factors (GCFs). The chapter ends with the all-important lessons on factoring polynomials employing the “reverse FOIL”, “guess and check”, and factoring by grouping techniques. Awe yeah!!! This chapter is pure math awesomeness!!!

### Chapter 10: Graphing and Solving Quadratic Equations
