Main Question or Discussion Point
I'm getting tired of getting wrong answers and going back and doing them again and again only to find there's a negative sign in the problem I didn't see through the gigantic problem I just finished. If I were doing an actual classroom and not an online that doesn't allow shown work... I'd at least get partial credit, and it's freaking me out, because I'm beginning to wonder if I'll pass this class because of it. I've practiced and practiced and I just don't seem to see the signs when it matters, and I don't know what to do, and don't want to give up, any advice?
