Understanding Absolute Value and Order of Operations

The video tutorial covers the concept of absolute value, explaining it as the distance from zero on a number line, and emphasizes that it is always positive. It provides examples to illustrate how to calculate absolute values. The tutorial then introduces the order of operations, explaining its importance in simplifying expressions. It uses the acronym GEMDAS, which stands for Grouping symbols, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). The video includes several examples to demonstrate how to apply the order of operations to solve mathematical expressions, including more complex problems involving fractions and nested operations.
