What is the product of -2 and 5?

1. 8

2. -10

3. 10

4. -8

The correct answer is: -10

The product of -2 and 5 can be found by adding 5 to itself -2 times. So, -2 * 5 = 5 + 5 + 5 + 5 + 5 = 25. However, since the factors have different signs, the product must be negative. Therefore, the correct answer is -10. Option A is incorrect because it is the sum of the two factors, rather than their product. Option C is incorrect because it assumes that the product of two negative numbers is always positive. Option D is incorrect because it is the negative version of the incorrect answer in option A.
