Understanding Additive Inverses and Number Lines

The video tutorial introduces the concept of opposite quantities and the additive inverse, explaining how the sum of a number and its opposite equals zero. It covers the properties of negative and positive numbers, their representation on a number line, and their real-world applications. The tutorial emphasizes understanding the additive inverse and its practical use in everyday scenarios.

What is the additive inverse of a number?

• A number that is twice the original number

• A number that, when added to the original number, equals zero

• A number that is half the original number

• A number that is the square of the original number

Where are negative numbers located on a number line?

• Above zero

• To the right of zero

• Below zero

• To the left of zero

Which of the following is NOT a characteristic of negative numbers?

• They represent a loss or decrease

• They are to the left of zero on the number line

• They increase as you move left on the number line

• They can indicate something below sea level

What does a positive number indicate?

• A position to the left of zero

• A decrease or loss

• A position below sea level

• A gain or increase

Which statement is true about positive numbers?

• They are the same as negative numbers

• They are to the right of zero on the number line

• They must always have a positive sign

• They decrease as you move right on the number line

How do you find the additive inverse of a number using a number line?

• By halving the number

• By squaring the number

• By finding the number's opposite on the number line

• By doubling the number

What is the result of adding a number to its additive inverse?

• A positive number

• A negative number

• Zero

• The original number

In real-world terms, what does a negative temperature indicate?

• A temperature at zero

• A temperature above zero

• A temperature that is increasing

• A temperature below zero

If Daniel earns $200 and spends it all, what is his remaining balance?

• $200

• $-200

• $100

• $0
