Integers

The video uses creative scenarios to explain integers and absolute values. It starts with an ocean depth analogy to introduce positive and negative numbers, followed by a skydiving ticket purchase to illustrate financial transactions with integers. The video then uses temperature changes to further explain integer operations. Finally, it covers the concept of absolute value, emphasizing its role in determining a number's distance from zero on a number line.

What does the narrative about ocean levels and skydiving primarily teach us about integers?

• Integers are only positive numbers.

• Integers can represent both positive and negative values.

• Integers are only used in financial contexts.

• Integers are not applicable in real life.

In the context of temperature, what does a negative integer indicate?

• A temperature above zero.

• A temperature below zero.

• A temperature exactly at zero.

• A temperature that is increasing.

If the temperature is -5 degrees and it rises by 8 degrees, what is the new temperature?

• 0 degrees

• 13 degrees

• -3 degrees

• 3 degrees

How does the concept of absolute value help us understand numbers?

• It helps in comparing two numbers directly.

• It shows the number's position relative to other numbers.

• It indicates the number's distance from zero, ignoring its sign.

• It tells us whether a number is positive or negative.

What is the absolute value of -9?

• -9

• 9

• 18

• 0
