北师大版四年级下册数学期中易错计算题集训

1、期中计算集训1、 直接写得数。1-0.25= 1.10.4= 4.9+0.1-4.9+0.1= 5.6+4= 7.54= 0.6-0.23= 0.861.2= 0.051.6=2.7+8.4= 0.9-0.3= 0.60.7= 6.2+0.04=12.58= 9.7-7= 12.510= 0.051000=0.06+6.34= 1-0.8= 5.7+0.3= 480.15 = 1.20.4= 0.010.8= 1.3+2.5= 26.2-13.1=0.64= 0.360.5= 4.56+0.39= 12.58=0.6-0.23= 3.20.2= 10-3.8= 1.3+0.45=6.9-0.6

2、9= 0.025000= 0.16+0.5= 6.1100=3.2100= 1.2+0.8= 10-0.6= 7.8+3.2=0.20.5= 9.7-7= 3.210= 3.20.1=63100= 0.234= 4.3-0.8= 12.58=2.6+2= 4.3-0.3= 1.52= 11-1.9=2.4+6= 5.3-3= 60.7= 1.5100=50.08= 5.4100= 0.21= 0.30.6=90.3= 0.350.1= 500.6= 2.54=0.40.4= 0.010110= 0.254= 0.810=2、 用竖式计算。18-6.27= 5.080.65 = 14.25300

3、= 11.65-7.39 = 9.80.5 = 15.4+2.96= 3.84= 21.7+2.86 = 16.05-9.7= 1.40.58= 1.087.5= 7200.45 = 18-7.28 = 9.80.5= 0.3212 = 4.15+0.8=8-1.36= 2.061.4= 5.93+8.07= 0.765.8=35.5+7.8= 100-68.34= 5.22.7= 460.35=35.7-8.5= 4.61.2= 100-45.8= 5.61.04=5.114.08= 32.520= 0.0120.55= 4.050.16=902.37= 4.53.68=3、 能简算的要简算

4、。37.25+28.7+12.75 23-1.58.212.5-1.68-2.32 7.2+24.4+13.38+5.60.7101-0.7 0.1254.780.253.70.4 0.866.4-0.865.44.2+5.82.3 5.81+8.3+4.19+11.74.53.6+5.53.6 45.342.5（17.48-9.86）1.2 70.8-1.25-1.750.259.54 （8+0.8）1.252.56.71-2.52.71 10.79-10.790.42.53.80.04 37.86-0.47-7.860.683.2+0.686.8 30-1.16-8.847.45+11.7+1.55+8.3 50.2（0.7+0.6）3.95.7+5.76.1 7.2+2.831.252.60.8 0.725.4+4.60.727.18+9.3+2.19+0.7 （8+0.8）1.253.21.9+6.81.9 0.125480
