Ordered n-tuples a. Is (1, 2, 3, 4) = (1, 2, 4, 3)? solution: a. No. By definition of equality of ordered 4-tuples, But 3 ≠ 4, and so the ordered 4-tuples are not equal. Example 1.2.7 — Cartesian Products Let A = {x, y}, B = {1, 2, 3}, and C = {a, b}. a. Find A x B solution: Example 1.2.8 — Strings
