四年级下册计算题库——小数的加法和减法
1.小数数位一样的加减法〔竖式计算〕
27.38+4.83= 26.75+2.83= 3.64-2.58= 6.52-3.44= 15.31+13.51=
5.5+4.5= 3.27-2.49= 11.65-7.39= 19.01-7.99= 7.51+0.49=
5.48-3.25= 4.8+18.9= 10.3+58.7= 8.03-4.56= 9.03-8.57=
8.25+1.55= 9.43-9.05= 1.75+2.08= 4.28-3.37= 4.13+2.24=
4.17+2.53= 5.07-0.98= 5.67-0.73= 13.18+5.27= 5.16+7.89=
2.小数数位不同的加减法〔竖式计算〕
26.8+3.02= 6.07-4.993= 3.7+2.36= 15.4+2.97= 10.2-8.75=
7.3-2.25= 3.8+3.54= 3.05-2.9= 3.1-2.07= 12.7+6.58=
7.81-3.735= 12.16+5.347= 0.4-0.125= 18.7+3.96= 9.6+4.78=
5.67-0.845= 0.506-0.19= 11.04-7.3= 1.4-0.405= 62.1-17.07=
1.4-0.405= 3.906+0.66= 43.5-27.34= 15.98-3.9= 75.6-3.55=
5.94+10.7= 12.03+0.875= 37.8+3.02= 0.704-0.25= 10.1-0.55=
3.整数与小数的加减法〔竖式计算〕
10+10.1= 27+8.03= 26+7.98= 13.99+1= 7.88+2 =
28-3.56= 10-0.81= 10-0.36= 20-0.92= 8-7.089=
95-9.85= 20-9.42= 35.09-11= 96.85-85= 45.45-45=
10-0.41= 45-0.45= 3.57+3=
4.小数加减混合运算〔递等式计算〕

20.8-〔15.98-3.9〕 32.5+〔5.07+6.13〕 3.52-〔4.66-3.82〕
5.小数加减简便运算〔递等式计算〕

30.99-〔8.5+15.99〕 72.6-〔22.6+3.45〕 36.06-〔5+6.06〕
