For example if i am using Z7, then first and foremost are the following correct?
-25 = 3
23 = 2
(just want to check im using modulo ok)
Then if i need to simplify 1/2 and 37/2 in Z7, then do i proceed the same? Im just wondering if the numbers have to be integers to use modulo?
At the minute i am thinkin that:
1/2 = 1/2 and
37/2 = 9/2
are these correct?
