🔹 Two integers are congruent mod 1 if their difference is divisible by 1 — which is always true. So every integer is equivalent to 0 .
If you’ve ever worked with modular arithmetic, you know ℤ/nℤ. But have you ever considered ?
Wait, Zmod1 has only one element? 🤯
🔹 0 + 0 ≡ 0, 0 × 0 ≡ 0.
🔹 Zmod1 = { [0] } That’s it. One residue class. 🔹 Two integers are congruent mod 1 if
Let’s talk about — the ring of integers modulo 1.
🔹 This is the trivial ring — the only ring (up to isomorphism) where 1 = 0. 🔹 Two integers are congruent mod 1 if
