Understanding Multiplication and Division with Negative Numbers

The video tutorial explains how to determine the sign of a product or quotient when multiplying or dividing numbers. It highlights that if there is an even number of negative numbers, the result is positive, and if there is an odd number, the result is negative. This rule applies to both multiplication and division.

What is the main focus when determining the sign of a product in multiplication?

How does the rule for determining the sign of a product apply to division?

• It applies in the same way as multiplication

• It applies only to positive numbers

• It does not apply

• It applies only to even numbers

What is the sign of the result when dividing numbers with an odd number of negative numbers?

• Positive

• Negative

• Zero

• Undefined

In the example provided, how many negative numbers were counted to determine the sign of the result?
