College Math CLEP Prep Practice Exam

What is the product of an integer and its opposite?

1. 0

2. the square of the original number

3. Twice the original number

4. Not enough information

The correct answer is: 0

When you multiply an integer by its opposite, you are essentially multiplying a number by its negative counterpart. This results in the product of 0 because the negative number cancels out the positive number, leaving you with 0 as the final result. Option B (the square of the original number) and option C (twice the original number) are incorrect because they do not account for the fact that the number being multiplied by its opposite is negative. Option D (not enough information) is also incorrect because the relationship between an integer and its opposite is a universal math concept that does not require any additional information.
