comment Solving systems of linear congruences with rational coefficients
@Ethan Thanks! Wow, that almost seems too easy. So multiplying both sides is a valid operation under congruence? This note from Wikipedia made me think not: "The next property, however, would fail if these variables were not all integers", which then demonstrates multiplication.

comment Floor function within a congruence
Yes, the constants $a_i$ are rational. Actually, they're integers with a single division. I just restated the problem to make this more clear.

comment Floor function within a congruence
No it's actually a linear expression, i.e. $a_1x_1+...+a_kx_k$ where $a_i$ are constants, not necessarily integers, and $x_j$ are variable integers.

comment What are imaginary numbers?
Excellent explanation! The first time I've seen the analogy of rotation was here, which also contains a really good, visual exploration of imaginary numbers: betterexplained.com/articles/…
