Why do we have the order of operations

The video tutorial explains the importance of the order of operations in mathematics, comparing it to language rules. It provides examples of how different approaches to solving expressions can lead to incorrect answers. The correct method, following the order of operations, is demonstrated to ensure consistent and accurate results.

Why are the order of operations compared to language rules?

• They are both optional guidelines.

• They both help in understanding complex concepts.

• They both ensure clarity and prevent confusion.

• They both are universally accepted without exceptions.

What happens if you don't follow the order of operations?

• You will always get the correct answer.

• You might end up with different answers.

• The problem becomes unsolvable.

• The expression simplifies automatically.

In the example given, what was the incorrect result when subtraction was done before multiplication?

• 21

• 5

• 13

• 25

What is the correct result of the expression when following the order of operations?

• 21

• 5

• 13

• 25

Why is it important for students to follow the order of operations?

• To allow for creative problem-solving.

• To avoid using calculators.

• To make the problem more challenging.

• To ensure they get the same answer as everyone else.
