Mastering the Order of Operations

The video reviews the order of operations, emphasizing its importance in solving math problems. It introduces GEMS as an alternative to PEMDAS, highlighting the role of grouping symbols and exponents. The video explains the correct order for multiplication, division, addition, and subtraction. A rap is used to help students memorize the order of operations. Finally, practice problems are solved step-by-step to reinforce the concepts.

• Because it is only used in Chapter 5.

• Because it is a new concept introduced in Chapter 5.

• Because it is not used in Chapter 5.

• Because it is essential for solving problems in Chapter 5.
