Решим примеры:
- $$14 \cdot 6 = (10 + 4) \cdot 6 = 10 \cdot 6 + 4 \cdot 6 = 60 + 24 = 84$$
- $$19 \cdot 4 = (20 - 1) \cdot 4 = 20 \cdot 4 - 1 \cdot 4 = 80 - 4 = 76$$
- $$15 \cdot 6 = (10 + 5) \cdot 6 = 10 \cdot 6 + 5 \cdot 6 = 60 + 30 = 90$$
- $$5 \cdot 20 = 100$$
- $$(48 + 12) : 6 = 60 : 6 = 10$$
- $$(36 - 27) : 3 = 9 : 3 = 3$$
- $$80 - 7 \cdot 8 = 80 - 56 = 24$$
- $$5 \cdot 7 + 65 = 35 + 65 = 100$$
Ответ: 84, 76, 90, 100, 10, 3, 24, 100
