[SOLVED] Binary Operations
I believe I understand the critera to see of something is a "group"
1.It must be binary
2.It must be associative
3.Must contain a Identity
4.Must have a inverse
My question is the how to read a problem.
For example:
All real numbers minus zero under the operation a*b = abs(ab), does this make a group. Not looking for a answer, as this is homework, but I am looking for a little help. Thanks
