$$sqrt3 + \frac{1}{3+sqrt3} - \frac{1}{3-sqrt3}$$

Can someone please suggest ways of solving such problems?

$$sqrt3 + \frac{1}{3+sqrt3} - \frac{1}{3-sqrt3}=sqrt3 + \frac{(3-sqrt3)-(3+sqrt3)}{(3+sqrt3)(3-sqrt3)}=\sqrt3 + \frac{-2\sqrt3}{9-3}=\sqrt3- \frac{\sqrt3}{3}=\sqrt3-\frac{1}{\sqrt3}=\frac{2}{\sqrt{3}}$$.

Hope it's clear.
