Additive Inverse Property (Part 1)

The video tutorial explains the concept of opposite numbers, which are equidistant from zero on a number line but on opposite sides. It introduces the additive inverse property, stating that the sum of a number and its opposite equals zero. The tutorial provides examples, such as -3 and 3, and demonstrates solving equations using additive inverses. It also includes an example with fractions, showing how -5.5 and 5.5 sum to zero.

What does it mean for two numbers to be opposites on a number line?

• They are both negative.

• They are both positive.

• They are equal to zero.

• They are the same distance from zero but on opposite sides.

Which of the following represents the additive inverse property?

• a * a = 0

• a + (-a) = 0

• a - a = 0

• a + a = 0
