Understanding Additive Inverses

The video tutorial explains the concept of additive inverse, which is the number that, when added to a given number, results in zero. It demonstrates this with examples: the additive inverse of negative 12 is positive 12, and the additive inverse of positive nine is negative nine. The tutorial also highlights that zero is a special case where it is its own additive inverse because zero plus zero equals zero.

What is the additive inverse of negative 12?

• Zero

• Negative 6

• Negative 24

• Positive 12

If a number is positive nine, what is its additive inverse?

• Positive 9

• Zero

• Negative 9

• Positive 18

How do you generally find the additive inverse of a number?

• Add 10 to the number

• Take the opposite of the number

• Multiply the number by 2

• Divide the number by 2

What is unique about the additive inverse of zero?

• It is negative one

• It is zero itself

• It is positive one

• It does not exist

Why is zero considered its own additive inverse?

• Because zero is not a number

• Because zero plus zero equals zero

• Because zero is a negative number

• Because zero is a positive number
