[1/1 Formula]
    Work: Calculate the value of equation 420+450+14*160+5*160+2*160+680+4*160-42*160 .
    Question type: Mathematical calculation
    Solution:
          420+450+14*160+5*160+2*160+680+4*160-42*160
        =420+450+2240+5*160+2*160+680+4*160-42*160
        =420+450+2240+800+2*160+680+4*160-42*160
        =420+450+2240+800+320+680+4*160-42*160
        =420+450+2240+800+320+680+640-42*160
        =420+450+2240+800+320+680+640-6720
        =870+2240+800+320+680+640-6720
        =3110+800+320+680+640-6720
        =3910+320+680+640-6720
        =4230+680+640-6720
        =4910+640-6720
        =5550-6720
        =-1170

    Answer:420+450+14*160+5*160+2*160+680+4*160-42*160=-1170
