What is PEMDAS or GEMDAS

The video tutorial explains the order of operations using the acronym PEMDAS (or GEMDAS), which stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. The instructor emphasizes the importance of following this order to solve mathematical expressions correctly. The tutorial includes a practical example to demonstrate how to apply PEMDAS, highlighting the need to work from left to right for multiplication, division, addition, and subtraction. The video also discusses the use of grouping symbols like parentheses and brackets.
