Understanding Negative Numbers

The video tutorial introduces negative numbers using a building analogy, where floors below ground level are represented as negative numbers. It further explains the concept using a vertical number line and extends the understanding to real-world examples like temperature variations in different locations. Finally, it summarizes the concept using a horizontal number line, emphasizing that negative numbers are less than zero and positive numbers are greater than zero.

What happens when you go one floor below the ground floor in a building?

• You reach level 1.

• You reach level 0.

• You reach level B1.

• You reach level B2.

How is level B1 represented on a vertical number line?

• As negative two

• As negative one

• As zero

• As positive one

What is the temperature in Moscow if it is five degrees below zero?

• 5 degrees Celsius

• 0 degrees Celsius

• Negative 10 degrees Celsius

What is the representation of 40 degrees below zero in Celsius?

• 40 degrees Celsius

• Negative 50 degrees Celsius

• Negative 40 degrees Celsius

• 0 degrees Celsius

What is the temperature in the Sahara Desert likely to be?

• 50 degrees Celsius

• 15 degrees Celsius

• Negative 40 degrees Celsius

• Negative 5 degrees Celsius

How are negative numbers positioned on a horizontal number line?

• Above zero

• To the right of zero

• To the left of zero

• Below zero

Which of the following is true about positive numbers on a number line?

• They are greater than zero.

• They are below zero.

• They are to the left of zero.

• They are less than zero.

If you move to the left on the number line, what happens to the numbers?

• They become more positive.

• They remain the same.

• They become more negative.

• They become zero.

What is the position of all positive numbers relative to zero on a number line?

• To the right of zero

• To the left of zero

• Below zero

• At zero

What happens to numbers when you move to the right on the number line?

• They become more negative.

• They become more positive.

• They remain the same.

• They become zero.
