小学生口算题卡---计应191（西）第三组马允

1，   计划

为一年级小学生设计口算题卡

2，   需求分析

2.1，用户故事

作为一个一年级小学生的家长，我希望制作一个出题软件，完成100以内的正整数的加减法题随机产生，一边减轻我的负担

2.2 技术难点

随机产生100以内的正整数

随机产生加减符号

减法负值的剔除

任务一

随机产生一组（10个）算题----产生算式剔除不够减，随机产生

任务二

显示一组算题，选择解答界面，完成按钮，同步计时（秒）

任务三

显示对错，统计正确率，统计时间

2，生成设计文档

3，设计复审

 室友帮忙查看

4，代码规范

    类名和方法名的定义要让其他人能看懂是什么意思，不要用a或b定义

5，具体设计

 6，具体编码
