(5)128× (6)(111+999)÷[56×(-)]
题型:计算题  难度:中档

答案

(1)原式=1÷÷4
                =÷4
                =
(2)原式=(-)÷
                =÷
                =
(3)原式=(×24+×24)×
                =(4+3)×
                =1
(4)原式=(-)++-+×10
                =×3+×10
                 =6
(5)原式=(126+2)×
                =17+
                =17
(6)原式=1110÷[56×-56×]
                =1110÷(24-21)
                =1110÷3
                =370
