(3)96.53-34.69-5.31(4)234.5-(36.73+34.5)
(5)15.3+2.8-5.3-1.8(6)4.35+8.6+15.65+1.4
答案

(1)原式=50.28-3.28-(5.4+4.6)

                = 47-10

                =37(2)原式=21.4+8.68-7.53

                =21.4+1.15

                =22.55

(3)原式=96.53-(34.69+5.31)

               =56.53(4)原式=234.5-34.5-36.73

                =163.27

(5)原式=15.3-5.3+2.8-1.8

                =11(6)原式= 4.35+15.65+(8.6+1.4)

                =30
