简算2357-1183-317-357
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：

2357-1183-317-357

=2357-357-(1183+317)

=2000-1500

=500

存疑请追问，满意请采纳

回答2：

=2357-357-（1183+317）=2000-1500=500，先计算能出整数的加减，最后再算就容易多了，全是口算解决

回答3：

2357-1183-317-357

=2357-357-1183-317...........交换律

=（2357-357）-（1183+317）

=2000-1500

=500

回答4：

原式＝（2357-357）-（1183+317）
