总结：

（1）我和胡新宇同学130201106 是一组的 博客地址http://www.cnblogs.com/hxy94264/

（2）我们两个做的是四则运算，有题目的范围 运算符的选择计时器到时间的操作 ，只需要在取值范围中轻轻的输入进去自己想要的范围就可以做题了呢，想做多少做多少。不想做了点击退出即可方便快捷，加减乘除做腻了呢可以点击普通版进去做一些带括号的负数的计算题，简单快捷易上手。

（3）在我们两个人做的过程中我主要负责程序界面设计通过从网上搜集资料问同学等等完成作业 

（4）优点：代码的复审过程很艰难也发现了一一部分问题认真的代码复审让我们可以进一步的完善此软件，两个人共同完成可以提高效率，减少出错的频率

   缺点：俩人想法不一致容易产生争执
