Practical Pre-Algebra (Part One)

By Dr Kwang S Ko, Nathan Y Ko, Dr. Kwang S. Ko

This is a study guide written primarily for middle and high schoolers in order for them to learn relevant math concepts at their level. There is an introduction before each chapter that describes what will be covered. Lessons such as number sense, decimals and fractions, and probability are explained before the exercises. Each concept has a step-by-step explanation on how to approach the problems. Afterwards, there is a self- test that assesses the knowledge of the student. Chapter 1 introduces basic concepts of algebra and teaches number sense based on the number system, algebraic expressions, and order of operations.Chapter 2 covers real numbers and teaches number sense in order to compute addition, subtraction, multiplication, and division problems expressed with two negative numbers. Absolute value, properties of equalities, and properties of real numbers are also included.Chapter 3 discusses solving linear equations. It shows how to solve equations with one or two variables using addition, subtraction, multiplication, and division. Problems involving rates, average speed, distance, and time are also included.Chapter 4 deals with graphing functions and discusses the graphing functions included plotting the coordinates, relating to function tables and finding the equations of function tables.Chapter 5 teaches how to graph linear equations and how to find derive linear equations from function tables, and also deals with parallel and perpendicular lines.
