答案

(1)原式=(10+40)×8

                = 400(2)原式=125×8×9

                =9000(3)原式=700+51×4

                =904

(4)原式=91×200

                =18200(5)原式= 43×(65+35)

                = 4300(6)原式=5600÷(25×4)

                =56

(7)原式=11.65-3.65+2.74

                =10.74(8)原式 =1.63+0.37+1.89-0.59

                 =3.3(9)原式=208+92+97

                =397

(10)原式=6467-1467+1832-832

                  =6000
