Answer 1

巧算3.82×10.1-38.2
解题思路：不能进行简便运算的按顺序计算，简便运算核心是运用加法和乘法各种定律进行计算，计算出整数部分方便后续计算的过程
解题过程：

3.82×10.1-38.2

=3.82×（10.1-10）

=3.82×0.1

=0.38

Answer 2

3.82×10.1-38.2
=38.2×1.01-38.2
=38.2×0.01
=0.382
简便的方法，就是先把3.82×10.1化为38.2×1.01。

Answer 3

3.82×10.1再减38.2等于多少,简便算法？
解析：
3.82×10.1-38.2
=3.82×10.1-3.82×10
=3.82×（10.1-10）
=3.82×0.1
=0.382

Answer 4

3.82×10.1-38.2
=3.82×（10+0.1）-38.2
=3.82×10+3.82×0.1-38.2
=38.2+0.382-38.2
=（38.2-38.2）+0.382
=0.382
.

Answer 5

依据题意列式计算如下:
3.82×10.1-38.2
=3.82×10+3.82×0.1-38.2
=（38.2-38.2）+0.382
=0.382
