Multiplying positive numbers always comes out positive, no matter how many there are. So you can forget about the positive ones.

the answer is positive, and if it's ODD, the answer is negative.
That monster product of eight numbers in problem #12 will be negative,
because there are an odd amount of negative factors in it.
