Order of Operations and Expressions

The video tutorial provides practice in evaluating complex expressions using the order of operations. It begins with an introduction and encourages viewers to attempt solving expressions independently. The tutorial explains the importance of grouping symbols like parentheses and brackets, and demonstrates solving two expressions step-by-step, emphasizing the correct sequence of operations: grouping, exponents, multiplication/division, and addition/subtraction.

What is the first step in evaluating expressions according to the video?

• Perform addition and subtraction

• Apply exponents

• Evaluate operations inside grouping symbols

• Multiply and divide from left to right

How are parentheses and brackets used differently in expressions?

• Brackets are used for subtraction

• Brackets are used for division

• Parentheses are used for addition

• They are used interchangeably for grouping
