能简算的要简算
(1)6.5×8+3.5×8-44= (2)907+907×9= (3)(999+111)÷[56×(-)]=
(4)56×99= (5)168.1÷(4.3×2-0.4)= (6)[2-(11.9-8.4×1)]÷1.3=
(1)原式=(6.5+3.5)×8-44
                =80-44
                 =36
(2)原式=907×(9+1)
                =907×10
                =9070
(3)原式=1110÷(24-21)
                =1110÷3
                =370
(4)原式=56×(100-1)
                =5600-56
               =5544
(5)原式=168.1÷(8.6-0.4)
                =168.1÷8.2
                =20.5
(6)原式=(2-0.7)÷1.3
                =1.3÷1.3
                 =1
