I have to do 8th grade math over the summer so i can do Pre algebra next year and i have no idea how to answer this question.

it says " Explain how to determine the sign of the product of a group of positive and negative integers without computing the product." I don't even really get what its asking.

Also I'm not cheating i just don't get it and my dad is out of town and my mom doesn't get it either. I think i could do it if i understood.

If you think about our presence, what do we contribute to nature? Waste, pollution, and death. We feed off of the earth and all of its inhabitants. So, aren't we parasites?

maybe you'd use the atom as a switch in the computer. or just make a little switch the size of an atom or smaller! maybe you could make a whole circuit board the size of an atom.

I just want to know how fuel cells work as I am doing research on it. Here is what I know.
I know that a fuel cell uses hydrogen to convert it into a form of electricity that the cars can use. There are exothermic reactions that release energy and endothermic reactions that absorb energy. Our goal is to separate the hydrogen from the water. so set up 2 equations
1. Water- 2H+O-energy
2. Water-2H+O+energy
we want to get energy and not to make it so we go for the first one right. I am a bit lose so please help
