Distributive property with a negative one ex1, -(19 + h)

The video tutorial explains the multiplication and altercation properties of -1, demonstrating how negative expressions can be rewritten using these properties. It emphasizes the importance of the distributive property in simplifying expressions involving negative numbers. The tutorial aims to clarify common misconceptions and provide a clear understanding of these algebraic concepts.

What is the multiplication property of negative one?

• It is used to add numbers together.

• It is a property that only applies to positive numbers.

• It states that multiplying by negative one changes the sign of a number.

• It allows you to multiply any number by zero.

How can the expression '-a' be rewritten using the multiplication property of negative one?

• As 1 - a

• As a * 1

• As -1 * a

• As a + 1

In the example given, how is the expression '-(19 + H)' rewritten?

• As H - 19

• As 19 - H

• As -1 * (19 + H)

• As 19 + H

What is the result of applying the distributive property to '-1 * (19 + H)'?

• 19 + H

• -19 - H

• 19 - H

• -19 + H
