Homework Statement
Suppose i and j take on values from {0,1,2,...,7}. We say that i and j are 'happy' if i - j (their difference) is congruent to 1.4 or 7 modulo 8.
Note: 'happy' is some mathematical property not relevant to the question.
What does 7 modulo 8 mean? What does it mean for i - j to be congruent to 1.4?
Thank you for your help!
