Order of Operations and Expressions

The video tutorial explains the order of operations in mathematics, emphasizing the sequence of solving expressions with multiple operations: parentheses first, followed by multiplication or division from left to right, and finally addition or subtraction from left to right. Through examples, the tutorial demonstrates how to apply these rules to solve expressions accurately, including the impact of changing the position of parentheses. The video concludes by encouraging viewers to practice these steps to improve their problem-solving skills.
