在上述小数加减法中,我们可以发现它们的数位不同。

但是,只要我们掌握了小数的加减法规则,就可以轻松地解决这些问题。

在计算时,我们需要注意小数点的位置,并将数位不足的数用0补齐。

例如,对于26.8+3.02,我们可以将3.02补
齐为3.020,然后按照竖式的方式进行计算。

同样地,对于
6.07-4.993,我们需要将4.993补齐为4.9930,然后进行计算。

整数与小数的加减法(竖式计算):
10+10.1=20.1
27+8.03=35.03
26+7.98=33.98
13.99+1=14.99
7.88+2=9.88
8-7.089=0.911
10-0.36=9.64
20-0.92=19.08
95-9.85=85.15
20-9.42=10.58
35.09-11=24.09
96.85-85=11.85
10-0.41=9.59
45-0.45=44.55
3.57+3=6.57
45.45-45=0.45
10.75+0.4=11.15
16.23+8.92=25.15
小数加减混合运算:
5.03-2.5=2.53
22.8-5.23=17.57
23.66+4.34=28
4.66-3.82=0.84
5.6-0.81=4.79
15.9+3.26=19.16
67.2+41.5=108.7
72.8-8.6=64.2
50-28.5=21.5
3.68+9.85=13.53
13.79-9.653=4.137
1.5+0.68=
2.18
15.98-3.9=12.08
32.5+5.07=37.57
以上是整数与小数的加减法和小数加减混合运算的竖式计算结果。
