What are Additive Inverses

The video tutorial explains the concept of additive inverses using a number line. It describes how two numbers are additive inverses if they are equal distances from zero but in opposite directions. The tutorial also covers the inverse property of addition, which states that a number plus its additive inverse equals zero. Examples are provided to illustrate how to find additive inverses and apply the inverse property of addition.

What is the additive inverse of positive 4?

• Positive 4

• Negative 4

• Zero

• Positive 8

What does the inverse property of addition state?

• The sum of a number and its inverse is always positive.

• The sum of a number and its inverse is always negative.

• The sum of a number and its inverse is zero.

• The sum of a number and its inverse is the number itself.

How do you find the additive inverse of a number?

• Multiply the number by 2.

• Divide the number by 2.

• Add 1 to the number.

• Change the sign of the number.

If you add a number to its additive inverse, what is the result?

• Double the original number

• The original number

• Zero

• Negative of the original number

Why are additive inverses important in mathematics?

• They help in solving equations.

• They are used to measure angles.

• They are used to find the area of shapes.

• They are used in multiplication.
