"Web17 de abr. de 2024 · This corollary tells us that for any a ∈ Z, a is congruent to precisely one of the integers 0, 1, or 2. Consequently, the integer a must be congruent to 0, 1, or 2, and it cannot be congruent to two of these numbers. Thus For each a ∈ Z, a ∈ C[0], a ∈ C[1], or a ∈ C[2]; and C[0] ∩ C[1] = ∅, C[0] ∩ C[2] = ∅, and C[1] ∩ C[2] = ∅. " - On z define * by a*b a
