Inverses and Identities

There are two basic INVERSE OPERATIONS

• ADDITIVE Inverses

• MULTIPLICATIVE Inverses

ADDITIVE Inverses

Use ADDITION and Subtraction to make zeros (0's)

Zero (0) is called the "ADDITIVE Identity"

Multiple Choice

f + 7 = 15

• Add 7 to both sides

• Multiply both sides by 7

• Divide both sides by 7

• Subtract 7 from both sides

Multiple Choice

What inverse operation will solve for h in the equation below?

3 + h = -9

• Add 3 to both sides

• Multiply both sides by 3

• Divide both sides by 3

• Subtract 3 from both sides

Multiple Choice

What inverse operation will solve for p in the equation below?

p - 13 = 7

• Add 13 to both sides
