所属专题 Addieren und Subtrahieren von ganzen und rationalen Zahlen
这是一个互动式整数运算练习应用。范例演示了整数的加法和减法运算规则，通过随机生成题目让学习者进行练习。核心数学概念包括整数的加法与减法运算、运算律的应用。构造要点：本范例使用了Shuffle命令实现题目随机打乱，Sequence命令生成题目序列，If命令进行条件判断实现答案验证，CountIf统计正确率，还使用了多个Textfield文本框接收用户输入，LaTeX命令格式化显示数学表达式，配合checkbox复选框和下拉菜单实现多类型题目选择。适合初中数学学段，用于课堂练习或课后巩固整数运算规则。
