Hi, I'm really confused about two's complement and octal.  

1.)  In two's complement, how can using the opposite and adding one change a 
number into the negative?  

2.)  If octal 7 is 111 in binary, what is 8 and 9?

I have some sample problems and I'll show you my answers for some of them.  
Please let me know if I'm on the right track or not.  Thanks!

Decimal: 37
Binary: 100101

Thank you again for your help!
