Explicație pas cu pas:
A = {a, b, c}
B = {d, e, f, g, h, i, j, k}
A x B = {(a, d); (a, e); (a, f); (a, g); (a, h); (a, i); (a, j); (a, k); (b, d); (b, e); (b, f); (b, g); (b, h); (b, i); (b, j); (b, k); (c, d); (c, e); (c, f); (c, g); (c, h); (c, i); (c, j); (c, k);}
Card A x B = 24 (A x B are 24 elemente)
