这是我上学期出给学生做的,加减乘除的都有,你看有没有合你心意的.公式1:a-b-c = a-(b+c)10-0.432 -2.568 9.3-5.26-2.7413.4-(3.4+5.2)14.9-(5.2+4.9)18.32-5.47-4.32 17.29-5.28-6.29 公式2:(axb)xc=ax(bxc)25*6.8*0.040.25*32*0.1256.4*1.25*

1、用竖式计算 0.396÷1.2= 0.756÷0.36= 15.6*13= 0.18*15= 0.025*14= 3.06*36= 0.04*0.12= 3.84*2.6≈ 5.76*3= (保留一位小数) 7.15*22 90.75÷3.3 3.68*0.25 16.9÷0.13 1.55÷3.9 3.7*0.016 13.76*0.8= 5.2*0.6 8.4*1.3 6.4*0.5 4.48*0.4 5.25*5

27*41= 42*40= 23*99= 41*20=43*46= 39*93= 76*72= 39*84=25*23= 54*37= 20*26= 78*88=66*57= 35*57= 14*78= 72*65=47*33= 43*98= 58*37= 47*23=87*10= 81*22= 42*11= 52*61=84*13= 35*96= 88*17= 88*94=15*46= 17*69= 11*
