题目内容

递等式计算。(能简算的要简算)
(1)2400÷(10×12)+375 (2)73.72-36.25-13.75 (3)102×54
(4)628-199 (5)(37+15)×85+1360 (6)4000÷125÷8
(7)323×101-323 (8)41.37-(14.95+10.37) (9)125×24×25
(1)原式=2400÷120+375
                =395
(2)原式=73.72-(36.25+13.75)
                =23.72
(3)原式=100×54+2×54
                =5508
(4)原式=628-(200-1)
                = 429
(5)原式=(50+2)×85+1360
                = 4250+170+1360
                =5780
(6)原式= 4000÷(125×8)
                = 4000÷1000
                = 4
(7)原式=323×(101-1)
                =32300
(8)原式= 41.37-10.37-14.95
                =16.05
(9)原式=125×8×3×25
                =75000
