Order of Operations and Parentheses

The video tutorial explains how to solve combined operations, which involve multiple arithmetic operations like addition, subtraction, multiplication, and division. It emphasizes the importance of following the correct order, known as the hierarchy of operations. Two main rules are highlighted: first, solve operations within parentheses, and second, perform multiplication and division before addition and subtraction. The tutorial provides examples with and without parentheses to illustrate these rules. Finally, viewers are encouraged to subscribe to the educational channel for more learning opportunities.

What are combined operations?

• Operations that combine different types of operations

• Operations involving only multiplication and division

• Operations that do not follow any specific order

• Operations involving only addition and subtraction

What is the first rule in the hierarchy of operations?

• Resolve operations inside parentheses first

• Resolve addition and subtraction first

• Resolve operations from left to right

• Resolve multiplication and division first

What should you do if there are no parentheses in a combined operation?

• Resolve operations in any order

• Resolve addition and subtraction first

• Resolve multiplication and division first

• Resolve operations from right to left

In the example without parentheses, what is the result of 4 multiplied by 2?

• 6

• 8

• 12

• 10

In the example without parentheses, what is the final result of the operation?

• 0

• 2

• -1

• 1

What is the first step in solving an operation with parentheses?

• Resolve multiplication and division first

• Resolve addition and subtraction first

• Resolve operations inside the parentheses first

• Resolve operations from left to right

In the example with parentheses, what is the result of 5 + 2 inside the parentheses?

• 9

• 6

• 8

• 7

In the example with parentheses, what is the result of 2 multiplied by 2 inside the parentheses?

• 3

• 4

• 2

• 5

In the example with parentheses, what is the final result of the operation?

• 5

• 4

• 3

• 2

What will help you avoid problems with the order of combined operations?

• Only using addition and subtraction

• Ignoring the rules

• Solving operations randomly

• Applying the two essential rules
