小学一年级100以内的加减法
1、计划：用c#编写一个小学生100以内口算题卡。
2、开发：
需求分析：作为一名一年级小学生的家长，我希望开发出一个口算题卡软件，让我的孩子能在上面练习口算题，能够自动生成100以内的正整数加减法运算，以便减轻我的工作负担。
难点：自动出10道题，然后进行解答。
代码规范：vs的代码规范。
具体设计：
3、PSP阶段
具体代码：

个人总结：在这次编译中，用到的是动态绑定的10道随机数学题，然后数组记录结果，和用户输入的结果进行比较，然后得出对错和正确率。用的是获取焦点的办法来完成对事件的计时。本次不足的地方，布局不是很好。以后也可以在上面进行升级 ，来完成更高年级的数学题的运算。
