Question

59乘以59加199的简便方法？

Answer 1

59×59+199脱式计算
解题思路：四则运算规则（按顺序计算、先算乘除后算加减，有括号先算括号，有乘方先算乘方）即脱式运算（递等式计算）需在该原则前提下进行
解题过程：

59×59+199

=3481+199

=3680

存疑请追问，满意请采纳

Answer 2

将199拆分59+140 进行计算 ：

59*59+199
=59*59+59+140
=59*（59+1）+140
=59*60+140
=3540+140
=3680

Answer 3

59x59＋199 ＝59x59＋59＋140 ＝59x（59＋1）+140 ＝59x60+140 ＝3540+140 ＝3680

Answer 4

59x59＋199
＝59x59＋59＋140
＝59x（59＋1）+140
＝59x60+140
＝3540+140
＝3680

Answer 5

59×59+199的简便计算是把199分成59和140进行简便计算。59x59+199
=59×59+59+140
=59x(59+1)+140
=59x60+140
=3540+140
=3680
