[tex]1 + \frac{1}{3} = 1 \frac{1}{3} \\ 1 \frac{1}{3} + \frac{1}{6} = 1 \frac{2}{6} + \frac{1}{6} = 1 \frac{1}{2} \\ 1 \frac{1}{2} + \frac{1}{2} = 2 \\ 2 + \frac{1}{3} = 2 \frac{1}{3} \\ 2 \frac{1}{3} + \frac{1}{6} = 2 \frac{2}{6} + \frac{1}{6} = 2 \frac{1}{2} \\ 2 \frac{1}{2} + \frac{1}{2} = 3 \\ 3 + \frac{1}{3} = 3 \frac{1}{3} \\ 3 \frac{1}{3} + \frac{1}{6} = 3 \frac{2}{6} + \frac{1}{6} = 3 \frac{1}{2} \\ 3 \frac{1}{2} + \frac{1}{2} = 4[/tex]
