Mastering Integer Addition Techniques

This video tutorial covers the concept of opposites and additive inverses in integers, explaining how they are the same distance from zero but on opposite sides. It demonstrates adding integers with the same and different signs using number lines and real-world examples. The tutorial includes practical exercises to reinforce understanding, such as finding the sum of temperatures and solving integer addition problems using the commutative property.

What is the opposite of the integer 5?

• -5

• 0

• 5

• -10

If the temperature is -5 degrees, what temperature would make the sum zero?

• -5 degrees

• 0 degrees

• 5 degrees

• 10 degrees

What is the sum of -7 and -3?

• 10

• -4

• 4

• -10

How do you find the sum of two negative integers?

• Subtract their absolute values and make the result negative

• Add their absolute values and make the result negative

• Add their absolute values and make the result positive

• Subtract their absolute values and make the result positive

What is the sum of 9 and -4?

• -13

• -5

• 5

• 13

When adding integers with different signs, what should you do?

• Subtract their absolute values and keep the sign of the smaller absolute value

• Add their absolute values and keep the sign of the smaller absolute value

• Subtract their absolute values and keep the sign of the larger absolute value

• Add their absolute values and keep the sign of the larger absolute value

Using the commutative property, what is the simplified form of 2 + (-2) + (-15)?

• -15

If the temperature is -3 degrees, drops 6 degrees, and then rises 4 degrees, what is the final temperature?

• 7 degrees

• 5 degrees

• -9 degrees

• -5 degrees
