1.小数数位相同的加减法(竖式计算)
27.38+4.83= 26.75+2.83= 3.64-2.58= 6.52-3.44=
5.31+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=
