Order of Operations - Advanced

Unit 4

This math unit advances students from basic to advanced understanding of the order of operations, also known as BEDMAS. Initially, the unit emphasizes memorizing the BEDMAS acronym and understanding what each letter represents for operations in mathematics. As the unit progresses, students practice applying these rules through increasingly complex scenarios. Beginning exercises focus on identifying the sequence of operations for basic arithmetic functions. Later, the worksheets introduce more challenging components such as parentheses and exponents. Advanced topics challenge students to practice order of operations in expressions that combine multiple operations, including long expressions without parentheses, and ones containing both parentheses and multiple arithmetic operations, often involving up to five numbers. This unit thoroughly prepares students to systematically break down and solve complex mathematical expressions by adhering to the hierarchy of operations.Skills you will learn include:

  • Solving with order of operations
  • Add, subtract, multiply, divide, brackets, exponent priority
  • BEDMAS acronym
