$[(9-6)-(7-3)]-[-(-3)+(-6+4) \\ \\ \lfloor 3-\left(7-3\right)\rfloor -\lfloor -\left(-3\right)-6+4\rfloor \\ \\ \lfloor 3-4\rfloor -\lfloor -\left(-3\right)-6+4\rfloor \\ \\ \lfloor -1\rfloor -\lfloor -\left(-3\right)-6+4\rfloor \\ \\ -1-\lfloor -\left(-3\right)-6+4\rfloor \\ \\ -1-\lfloor 3-6+4\rfloor \\ \\ -1-\lfloor -3+4\rfloor \\ \\ -1-\lfloor 1\rfloor \\ \\ -1-1 = -2$
