Dear Sal,
I keep getting answers but with different +,- signs in front. For example i would get -1 and +6 and type that in. The website says that i'm wrong and that the answers are +1 and -6. It seems my answers are always have a different plus or minus in front of them. I've checked my math, yet still odd answers.
