(竖式计算,后两行要验算)
4.8+18.9= 10.3+58.7= 8.03-4.56= 9.03-8.57= 15.4+2.97= 7.81-3.735=
26.8+3.02= 6.07-4.993= 3.7+2.36= 3.05-2.9= 3.1-2.07= 1.4-0.405=
7.3-2.25= 3.8+3.54= 12.16+5.347= 0.4-0.125= 18.7+3.96= 11.04-7.3=
10+10.1= 27+8.03= 26+7.98= 13.99+1= 45-0.45= 8-7.089= 10-0.81=
5.67-0.845= 0.506-0.19= 1.4-0.405= 3.906+0.66= 43.5-27.34= 15.98-3.9=
