a) $$2 \cdot 14 + 6 \cdot 2 = 2 \cdot (14 + 6) = 2 \cdot 20 = \mathbf{40}$$
г) $$22 \cdot 3 - 3 \cdot 2 = 3 \cdot (22 - 2) = 3 \cdot 20 = \mathbf{60}$$
ж) $$18 \cdot 1.2 + 2 = 18 \cdot 1.2 + 18 \cdot \frac{2}{18} = 18 \cdot (1.2 + \frac{1}{9}) = 18 \cdot (1.2 + 0.111...) = 18 \cdot (1.311...) = 23.6 \approx \mathbf{23.6}$$
