What do you get when you combine opposite quantities?

10 + (-10) = ?

For example:


In this lesson, you will learn the additive inverse by combining opposite quantities.


Absolute Value is a number’s distance from zero.

| -3 | =

3

-3


Opposite Numbers have the same absolute value.

| 3 | =

| -3 | =

3

If I walk forward 5 steps, but then walk backwards 5 steps, where am I?

(-5)

= 0


10 + (-10) =

0

Two numbers that can be added together to get zero are called an Additive Inverse.

-15 + 15 =

0


In this lesson, you have learned about the additive inverse by combining opposite quantities.


What number can be inserted to show the additive inverse?

(-9)

9+ = 0


  • Complete the adding tree:

  • 33

  • -33

What number needs to be inserted to make the statement true?

-3 + 5 + 3 + = 0
