Do you want to ace your next exam by mastering Pre-Algebra? Our Pre-Algebra course features step-by-step video lectures, written lessons, practice tests, and quizzes. ALL PRACTICE PROBLEMS AND QUIZ PROBLEMS ARE FULLY SOLVED WITH OPTIONAL STEP-BY-STEP SOLUTION VIDEOS. In addition to this, each section has a bonus practice test with full step-by-step solutions. If you take this course, you will fully understand all of the fundamental ideas of pre-algebra. Higher math classes like Algebra, Geometry, Trigonometry, and Calculus rely heavily on the principles you'll study. We'll go over operations with whole numbers before moving on to integers, fractions, and decimals. We'll finish up with learning how to calculate the mean, median, and mode of a set of values, as well as how to convert between different units of measurement.
