Exploring Absolute Value and Order of Operations

This video tutorial covers the concepts of absolute value and order of operations. It begins with an explanation of absolute value, emphasizing that it represents the distance of a number from zero, always positive. The tutorial then demonstrates how to evaluate expressions involving absolute value. Following this, the order of operations is introduced using the acronym PEMDAS, which stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. The video provides examples of solving problems using these rules, highlighting the importance of performing operations in the correct sequence.
