Simplifying an expression by adding and subtracting

The video tutorial explains how to use the order of operations to solve a math problem. It begins with an introduction to the concept, followed by the application of the distributive property to remove parentheses. The tutorial then covers the concept of double negatives, comparing it to English grammar, and explains how subtracting a negative number results in addition. Finally, the video demonstrates the step-by-step simplification of the expression, working from left to right, to reach the final solution.

What is the first step in solving an expression with parentheses using the order of operations?

• Subtract all numbers first

• Add all numbers first

• Multiply all numbers first

• Use the distributive property to eliminate parentheses

What does the distributive property help you do in an expression?

• Add numbers in sequence

• Distribute a number across terms inside parentheses

• Subtract numbers in sequence

• Combine like terms

In mathematics, what happens when you subtract a negative number?

• It becomes a larger negative number

• It remains the same

• It becomes a positive number

• It becomes zero

How is a double negative in math similar to a double negative in English?

• Both result in zero

• Both result in a negative

• Both result in a positive

• Both result in confusion

What is the final result of simplifying the expression using the order of operations?

• Positive 4

• Negative 4

• Zero

• Positive 2
