z这道题的简便算法是什么?
(-3.14)乘35.2加6.28乘(-23.3)减1.57乘36.4

-3.14(35.2+46.6)-1.57*36.4=-3.14(35.2+46.6)-3.14*18.2=-3.14(35.2+46.6+18.2)=-3.14*100=-314补充:-3.14(35.2+46.6)-1.57*36.4=-3.14(35.2+46.6)-3.14*18.2=-3.14(35.2+46.6+18.2)=-3.14*100=-314就...您能答得清晰些吗???-3.14*35.2+6.28*(-23.3)-1.57*36.4=(-110.528)+(-146.324)-57.148=(-256.852)-57.148=-199.704
