Answer:
Positive
Step-by-step explanation:
A negative number multiplied by a negative number is always a positive number. So multiplying an even number of negative numbers, will always result in a positive product. For example:
[tex](-1)*(-1)=1\\[/tex]
or
[tex](-2)*(-2)*(-2)*(-2)*(-2)*(-2)=64[/tex]
If you have an odd number of negative numbers, the product will be negative, because not all the negatives would cancel.
