Mastering the Order of Operations with PEMDAS

The video tutorial explains the order of operations using the PEMDAS rule, which stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. It covers the priority of operations, demonstrating with examples how to correctly simplify expressions. The tutorial also discusses the role of exponents and parentheses, and how to handle fractions in operations.
