These are tricky. I have worked on them for hours, and don't know what they are.

If anyone wants interesting problems tell me. ( I kow the answers to those )
1) uff, my minds running a bit of blank when it comes to absolute values. So I really dont think this is correct, but I got .1 and 0 for my answers. Checking them it works, but I still dont really know.

2) sorry broski, dont remember anything from geometry.
