Mastering Order of Operations with Parentheses

Maria and her mascot Matthew teach the order of operations focusing on addition and subtraction. The lesson covers the importance of parentheses in calculations, demonstrating how they affect the outcome. Through various examples and practice problems, students learn to solve expressions both with and without parentheses. The video also includes writing number sentences to match word problems and solving complex expressions and puzzles, emphasizing the correct order of operations.

What is the first step in the order of operations as discussed in the video?

• Drawing bubbles around operations

• Solving inside the parentheses

• Subtraction from right to left

• Addition from left to right

If an expression has no parentheses, how should it be solved according to the video?

• From right to left

• Any order is acceptable

• Only subtraction first

• From left to right

What effect do parentheses have on the order of operations?

• They only affect addition

• They change the numbers involved

• They dictate the first operation to perform

• No effect

In the absence of parentheses, how did Maria suggest handling operations?

• Ignoring the standard rules

• Solving from left to right

• Starting with the highest numbers

• Using balloons for visualization

What is the result of the operation '50 minus 5 plus 3' as solved in the video?

• 58

• None of the above

• 48

• 45

How does Maria suggest you write an operation that starts with subtraction?

• Using parentheses around the entire expression

• Placing the subtraction at the beginning

• Starting with addition for simplicity

• Subtracting the smallest number first

What is the correct result of '80 minus 60 plus 40' as discussed?

• 20

• 160

• 100

• 60

In the expression '5 plus 7', what is the result as calculated in the video?

• 12

• 222

• 14

• None of the above

How did Maria suggest checking the truth of an expression with potential parentheses placement?

• By consulting a textbook

• By subtracting first

• By adding first

• By testing different placements

What was the final correct result for the expression '16 minus 2 plus 6' with correct parentheses placement?

• 22

• 8

• 20

• 14
