Для начала решим примеры на вычитание столбиком:
$$9020 - 453 = 8567$$
$$4080 - 2196 = 1884$$
$$7040 - 6451 = 589$$
$$6050 - 4862 = 1188$$
Теперь решим примеры на умножение:
$$16 * 9 = (10 + 6) * 9 = 90 + 54 = 144$$
$$35 * 8 = (30 + 5) * 8 = 240 + 40 = 280$$
$$55 * 3 = (50 + 5) * 3 = 150 + 15 = 165$$
$$62 * 7 = (60 + 2) * 7 = 420 + 14 = 434$$
$$45 * 4 = (40 + 5) * 4 = 160 + 20 = 180$$
$$4 * 26 = 4 * (20 + 6) = 80 + 24 = 104$$
$$7 * 23 = 7 * (20 + 3) = 140 + 21 = 161$$
$$5 * 47 = 5 * (40 + 7) = 200 + 35 = 235$$
$$3 * 19 = 3 * (10 + 9) = 30 + 27 = 57$$
$$6 * 52 = 6 * (50 + 2) = 300 + 12 = 312$$
Решим примеры на деление:
$$64 : 4 = (40 + 24) : 4 = 10 + 6 = 16$$
$$96 : 8 = (80 + 16) : 8 = 10 + 2 = 12$$
$$75 : 5 = (50 + 25) : 5 = 10 + 5 = 15$$
$$84 : 3 = (60 + 24) : 3 = 20 + 8 = 28$$
$$64 : 2 = (60 + 4) : 2 = 30 + 2 = 32$$
$$96 : 6 = (60 + 36) : 6 = 10 + 6 = 16$$
