{tex}{1 \over 2} + \left( {{{ - 1} \over 6}} \right) + \left( {{{ - 2} \over 3}} \right) + {2 \over 6}{/tex}

= {tex}{1 \over 2} - {1 \over 6} - {2 \over 3} + {2 \over 6}{/tex}

= {tex}{1 \over 2} - {2 \over 3} + \left( {{2 \over 6} - {1 \over 6}} \right){/tex}

= {tex}{1 \over 2} - {2 \over 3} + {1 \over 6}{/tex}

= {tex}{1 \over 2} + \left( {{1 \over 6} - {2 \over 3}} \right){/tex}

= {tex}{1 \over 2} + \left( {{{1 - 4} \over 6}} \right){/tex}

= {tex}{1 \over 2} - {3 \over 6}{/tex}

= {tex}{1 \over 2} - {1 \over 2}{/tex}

= 0
