Question

8.5-(4.38+1.56)怎样简便计算？

Answer 1

8.5-(4.38+1.56)=8.5-(4.38+1.5+0.06)=8.5-1.5-(4.38+.0.02+0.04)=7-4.44=7-4-0.44=3-0.44=2.56, 此为运算步骤!!!!

Answer 2

8.5-(4.38+1.56)=8.5-(4+0.38+1.5+0.06)=8.5-5.5-0.44=3-0.44=2.56
验算：8.5-(4.38+1.56)＝8.5-5.94＝2.56

Answer 3

简便计算过程如下：

1、提取原式：8.5-(4.38+1.56)

2、计算过程：

      =8.5-5.94

      =8.5-6+0.06

      =2.5+0.06

      =2.56

3、计算结果：2.56

Answer 4

8.5-(4.38+1.56)
=8.5-1.56 -4.38
=8.5 -1.5 +(0.6+4.38)
=7-4.98
=7-5 +0.02
=2+0.02
=2.02

Answer 5

=8.5－7.94
=8.5－8+0.06
=0.5+0.06
=0.56
