easy-looking vector prob: If Ax(BxC) = Bx(CxA), [ABC] * 0, then value of Ax(BxC) is ?

If Ax(BxC) = Bx(CxA) and [ABC] * 0, then the value of Ax(BxC) is ?
Do the x's indicate multiplication? Is "[ABC]" the determinant of the product of A, B, and C? What is meant by "*0"?

When you reply, please include a clear listing of your thoughts and efforts so far. Thank you! ;)
