Dive into the foundational concepts of mathematics with this essential review of Numbers, Sets, and and Operations.

This video guides you through essential arithmetic skills, including performing basic operations (addition, subtraction, multiplication, and division), finding averages and maximums, and simplifying numerical expressions. We also cover how to determine whether given inequalities are true or false, and how to arrange numbers in order.

Master geometric and number line concepts by learning how to find the distances and midpoints of segments based on coordinates. We also tackle angle problems, including determining the measure of a straight angle, identifying a right angle (∠ACD), and finding the measure of ∠DCB within a diagram.

A crucial section is dedicated to set theory, showing how to list the elements of given sets (A and B) within a universe (U), and calculating specific set operations like A∩B, A∪B, and complements. We also practice defining sets based on rules, such as listing odd whole numbers less than 13.

Finally, solidify your understanding of the properties of numbers by matching key rules—including the Associative Property of Multiplication/Addition, the Commutative Property of Addition/Multiplication, the Identity Elements (for Addition and Multiplication), the Distributive Property, and the Multiplication Property of Zero—to their appropriate mathematical applications. This review is essential for reinforcing core math principles!.
