简便运算:9.5+3.75-6.23简便运算:10.66+0.4-9.86简便运算:9.5+3.75-6.23简便运算:10.66+0.4-9.86简便运算:9.5+3.75-6.23简便运算:10.
简便运算:9.5+3.75-6.23简便运算:10.66+0.4-9.86
简便运算:9.5+3.75-6.23
简便运算:
10.66+0.4-9.86
简便运算:9.5+3.75-6.23简便运算:10.66+0.4-9.86
先算9.5 - 6.23 =3.27
然后3.27 + 3.75 = 7.02
如果化成算式就是:9.5 - 6.23 + 3.75
10.66+0.4-9.86
=10.66-9.86+0.4
=0.8+0.4
=1.2
貌似先算3.75-6.23简便一点
9.5+3.75-6.23=9.5+0.5+3.25-6.23=13.25-6.23=7.02
10.66+0.4-9.86=10.66+0.14-10+0.4=10.8-10+0.4=1.2
