How can u find the sign of the product of two or more rational numbers

If it is two negatives its a positive, if its a negative and one positive it will be negative.  but if its two positive its positive
(-)+(-)=(+)             
(-)+(+)=(-)           
(+)+(+)=(+)

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
