Mastering Order of Operations with Parentheses

Maria and her mascot Matthew teach the order of operations focusing on addition and subtraction. The lesson covers the importance of parentheses in calculations, demonstrating how they affect the outcome. Through various examples and practice problems, students learn to solve expressions both with and without parentheses. The video also includes writing number sentences to match word problems and solving complex expressions and puzzles, emphasizing the correct order of operations.
