For this problem you can consider things such as 1/2 as the multiplicative inverse of 2. Then you have to ask, what element in Z7 is an inverse of 2? 2*4=8 and 8=1 in Z7 so a reasonable interpretation for 1/2 is 4. You can find reasonable interpretations for the other expressions in a similar fashion.

I understand what we are doing here, but what are we supposed to do for something like $ \sqrt{-3} $? --Podarcze 11:34, 11 March 2009 (UTC)
