Mastering Order of Operations for Expression Simplification

What is the first step in simplifying expressions using order of operations?

• Multiply and divide from left to right

• Add and subtract from left to right

• Circle terms and highlight unprotected addition or subtraction signs

• Simplify within parentheses first

What does circling terms help to identify?

• The terms that need to be simplified first

• The terms outside of parentheses

• The terms that can be ignored

• The final answer

What should be done after circling the terms?

• Simplify the terms inside the circles

• Erase all circles

• Add all the terms together

• Subtract the terms from each other

In the first example, what is the final answer after simplification?

• 16

• 4

• 20

• 7

Why can't addition or subtraction signs inside parentheses be highlighted?

• Because they are errors in the expression

• Because they do not affect the order of operations

• Because they are protected and need to be dealt with in their own terms

• Because they are already simplified

What is the result of simplifying the first term in the second example?

• 8

• 24

• 27

• 12

What is the importance of simplifying operations within parentheses first?

• It is a personal preference

• It is the last step in the order of operations

• It helps in accurately following the order of operations

• It makes the expression look simpler

In the second example, what is the final answer after all simplifications?

• 59

• 12

• 47

• 7

What strategy is emphasized throughout the tutorial for simplifying expressions?

• Using a calculator for all steps

• Ignoring order of operations

• Guessing and checking

• Circling terms and highlighting unprotected signs

Why is it important to follow the order of operations from left to right for addition and subtraction?

• There is no specific reason

• Because addition is always done before subtraction

• Because it is easier than doing it right to left

• To ensure the correct final answer
