2) ($$\frac{1}{9}$$ + $$\frac{1}{4}$$ - $$\frac{1}{18}$$) $$\cdot$$ 36 = ($$\frac{1 \cdot 4}{9 \cdot 4}$$ + $$\frac{1 \cdot 9}{4 \cdot 9}$$ - $$\frac{1 \cdot 2}{18 \cdot 2}$$) $$\cdot$$ 36 = ($$\frac{4}{36}$$ + $$\frac{9}{36}$$ - $$\frac{2}{36}$$) $$\cdot$$ 36 = $$\frac{4+9-2}{36}$$\cdot$$ 36 = $$\frac{11}{36}$$\cdot$$ 36 = 11
