(10 + 8) * 3 = 10 * ☐ + ☐ * 3
(40 + 6) * 2 = ☐ * 2 + ☐ * ☐
(☐ + ☐) * 3 = 7 * 3 + 8 * 3
(10 + 8) * 3 = 10 * 3 + 8 * 3
(40 + 6) * 2 = 40 * 2 + 6 * 2
(7 + 8) * 3 = 7 * 3 + 8 * 3
Решение примеров полностью:
(10 + 8) * 3 = 10 * 3 + 8 * 3 = 30 + 24 = 54
(40 + 6) * 2 = 40 * 2 + 6 * 2 = 80 + 12 = 92
(7 + 8) * 3 = 7 * 3 + 8 * 3 = 21 + 24 = 45
