For this case we must say that it is obtained by multiplying any even number of negative numbers, that is, if a positive or negative number is obtained.
We must bear in mind that the Law of Signs states that:
\(+ * + = +\\+ * - = -\\- * + = -\\- * - = +\)
For example:
Let -a, -b, -c, -d negative numbers, we have:
- A pair: \((-a) * (- b) = + ab\)
- Two pairs: \((-a) * (- b) * (- c) * (- d) = (+ ab) * (+ cd) = + abcd\)
This is true for the multiplication of any pair of negative numbers.
So, the answer is: You get a positive number
Answer:
A positive number is obtained
