GreeneMath | Pre-Algebra
In this course, you will master the basic concepts of pre-algebra using GreeneMath.com's three-step system. These concepts are fundamental to success in higher math classes such as Algebra, Geometry, and Calculus. We will review operations with whole numbers, then move on to learn how to perform operations with integers, fractions, and decimals. We will wrap up our course by learning how to find the mean, median, and mode for a group of numbers, along with how to convert between various units of measurement.
