Answer 2

When multiplying negative numbers together, the rule is that an odd number of negative factors will result in a negative product, while an even number of negative factors will yield a positive product. In this case, we have four negative factors, so the product will be positive.

Let's calculate it step by step:

(-7) × (-0.5) × (-3) × (-2)

First, we'll multiply -7 and -0.5:

(-7) × (-0.5) = 3.5

Now, we have:

3.5 × (-3) × (-2)

Next, we multiply 3.5 and -3:

3.5 × (-3) = -10.5

Finally, we multiply -10.5 and -2:

-10.5 × (-2) = 21

Therefore, (-7) × (-0.5) × (-3) × (-2) equals 21.
