Question

If $\to a, \to b$ and $\to c$ are three non-coplanar vectors and $\to p, \to q$ and $\to r$ are vectors defined by $\to p = \frac{\to b \times \to c}{[\to a \to b \to c]}, \to q = \frac{\to c \times \to a}{[\to a \to b \to c]}$ and $\to r = \frac{\to a \times \to b}{[\to a \to b \to c]}$ , then the value of
$(\to a + \to b) \cdot \to p + (\to b + \to c) \cdot \to q + (\to c + \to a) \cdot \to r =$
