  1. 7395 × 217 = 7395 × (200 + 10 + 7) = 1 479 000 + 73 950 + 51 765 = 1 604 715.

  2. 6951 × 136 = 6951 × (100 + 30 + 6) = 695 100 + 208 530 + 41 706 = 945 336.

  3. 2603 × 574 = 2603 × (500 + 70 + 4) = 1 301 500 + 182 210 + 10 412 = 1 494 122.

  4. 1947 × 369 = 1947 × (300 + 60 + 9) = 584 100 + 116 820 + 17 523 = 718 443.
