Order of Operations Explained

In this video, Ms. Arden introduces the concept of order of operations, also known as PEMDAS, which stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. She explains the importance of following this order to correctly solve mathematical expressions. The video includes a detailed breakdown of each step in PEMDAS, with examples and practice problems to reinforce learning. Students are encouraged to write down notes and practice solving expressions using the order of operations. The lesson concludes with a recap and a challenge for students to try additional problems on their own.
