Order of Operations and DMAS Rule

The video tutorial introduces the order of operations, known as the DMAS rule, which stands for Divide, Multiply, Add, and Subtract. It explains the importance of following this order when solving mathematical problems with multiple operations. The tutorial provides two examples to demonstrate the application of the DMAS rule, guiding viewers through each step to simplify expressions correctly. By the end of the video, viewers should understand how to apply the DMAS rule to solve mathematical problems efficiently.
