Why do we use use parenthesis and brackets

The video tutorial explains the use of parentheses and brackets in algebraic expressions, emphasizing their role in altering the order of operations. Through a practical scenario, it demonstrates how parentheses can be used to ensure all components of an expression are correctly multiplied or added. The tutorial also clarifies that brackets and parentheses serve the same purpose, with brackets often used for differentiation. Overall, the video aims to enhance understanding of how these symbols help organize and prioritize mathematical operations.

Why do we use parentheses in algebraic expressions?

• To change the order of operations

• To eliminate multiplication

• To make expressions look complex

• To avoid using numbers

In the given scenario, why is it important to use parentheses?

• To divide the total by 2

• To add $5 after doubling

• To ensure the $5 is doubled

• To subtract $5 before doubling

What is the main reason for using brackets instead of parentheses?

• To make expressions more colorful

• To differentiate between different operations

• To avoid using numbers

• To reduce the number of operations

What do parentheses and brackets help us achieve in mathematical expressions?

• Organize and prioritize operations

• Make expressions longer

• Remove the need for addition

• Simplify all expressions

How do parentheses affect the order of operations?

• They make all operations equal

• They eliminate the need for multiplication

• They allow certain operations to be performed first
