3. Вычислить: $$17-5-13-3=$$ $$6 \cdot 14+75:5=$$ $$100-23 \cdot 3+63=$$ $$14 \cdot 4+12 \cdot 3=$$ $$3 \cdot 27-3 \cdot 24=$$ $$7+23 \cdot 4-16=$$

3. Вычисляем: $$17-5-13-3 = 12 - 13 - 3 = -1 - 3 = -4$$ $$6 \cdot 14+75:5 = 84 + 15 = 99$$ $$100-23 \cdot 3+63 = 100 - 69 + 63 = 31 + 63 = 94$$ $$14 \cdot 4+12 \cdot 3 = 56 + 36 = 92$$ $$3 \cdot 27-3 \cdot 24 = 81 - 72 = 9$$ $$7+23 \cdot 4-16 = 7 + 92 - 16 = 99 - 16 = 83$$
