团队成员：陈淑筠、杨家安、陈曦
团队选题：小学四则运算APP
第一次冲刺阶段时间：11.17~11.27
本次发布我们增加了CalculatorsActivity.java、YunsuanActivity.java、ResultActivity.java这三个Activity，主要有MainActivity.java、TypesActivity.java、CalculatorActivity.java、CalculatorsActivity.java、YunsuanActivity.java、ResultActivity.java这六个Actvity，其中MainActivity.java：主界面，TypesActivity.java：按了主界面中的“进入”按钮后，跳到练习题类型选择“单题练习”或“多选择练习”，CalculatorActivity.java：是“单题练习“界面，CalculatorsActivity.java：是”多选择练习“的提供给用户的选择功能界面，YunsuanActivity.java：是”多选择练习“的按用户选择的功能的出题界面。
新增的代码和界面如下：
