Multiplying Integers

This video tutorial covers the multiplication of integers, focusing on the rules for multiplying integers with the same and different signs. It also reviews multiplication properties like the zero and identity properties. The lesson extends to evaluating powers with negative bases, emphasizing the importance of parentheses in expressions. The tutorial includes examples and exercises to reinforce understanding.

What should you consider before multiplying integers to determine if the product will be positive, negative, or zero?

• The sum of the integers

• The signs of the integers

• The difference between the integers

• The quotient of the integers

According to the multiplication property of zero, what is the product of any number and zero?

• The number itself

• Zero

• One

• Negative of the number

What does the identity property of multiplication state about multiplying any number by one?

• The product is negative

• The product is the number itself

• The product is one

• The product is zero

What is the result when two integers with the same sign are multiplied?

• Positive

• Zero

• Undefined

• Negative

What is the product of two integers with different signs?

• Positive

• Negative

• Zero

• The larger integer

What does the exponent in a power expression indicate?

• The number of times the base is added

• The number of times the base is multiplied by itself

• The number of times the base is subtracted

• The number of times the base is divided

When writing a power expression with a negative base, what is crucial to include?

• A positive sign

• Parentheses around the base

• A negative exponent

• A zero exponent

What happens to the product when a negative base is raised to an even exponent?

• The product is undefined

• The product is zero

• The product is positive

• The product is negative

If a negative base is raised to an odd exponent, what will the product be?

• Undefined

• Positive

• Negative

• Zero

In the expression (-3)^2, what is the base and what is the result?

• Base is -3, result is -9

• Base is 3, result is -9

• Base is -3, result is 9

• Base is 3, result is 9
