If $\overrightarrow{a} \times \overrightarrow{b}=c, \overrightarrow{b} \times \overrightarrow{c}= \overrightarrow{a}$ and $\overrightarrow{c} \times \overrightarrow{a}= \overrightarrow{b}$ then $(\overrightarrow{a} . \overrightarrow{b} \times \overrightarrow{c}) + \overrightarrow{b} . (\overrightarrow{c} \times \overrightarrow{a})+ \overrightarrow{c}. (\overrightarrow{a} \times \overrightarrow{b})$ is equal to
