(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
答案

(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
