Perform the following multiplications: 23 x 9 67 x 11 67 x 64 17 x 84 11 x 58 48 x 9 11 x 62 11 x 34 38 x 11 90 x 65 94 x 11

Решение:

Выполним умножение чисел столбиком.

1. \( 23 \times 9 = 207 \)
2. \( 67 \times 11 = 67 \times (10 + 1) = 670 + 67 = 737 \)
3. \( 67 \times 64 = 4288 \)
4. \( 17 \times 84 = 1428 \)
5. \( 11 \times 58 = 638 \)
6. \( 48 \times 9 = 432 \)
7. \( 11 \times 62 = 682 \)
8. \( 11 \times 34 = 374 \)
9. \( 38 \times 11 = 418 \)
10. \( 90 \times 65 = 5850 \)
11. \( 94 \times 11 = 1034 \)

Ответ: 207, 737, 4288, 1428, 638, 432, 682, 374, 418, 5850, 1034.
