摘要： A graphing calculator (10) having an X=Editor with inequalities. The calculator (10) is programmed to provide an X=Editor which displays one or more “X=” to allow input of a vertical line inequality. The X=Editor allows the user to input an inequality symbol and a constant for each X, allows the user to select or deselect each X, and a graph function to graph each selected X on the X=Editor display.

摘要： A graphing calculator (10) or other computer based teaching tool that displays inequalities on a display screen. In contrast to prior art devices, the present invention provides displays of inequalities that are mathematically correct and consistent with non-electronic display of inequalities such as textbooks and black board representations to reinforce traditional teaching methods and help the student or user to readily see and understand the mathematical concepts involved. The display methods of the present invention are particularly useful for small, low-resolution displays that are typical of handheld computers and calculators.
摘要翻译：图形计算器（10）或其他基于计算机的教学工具，其在显示屏幕上显示不等式。与现有技术装置相反，本发明提供了数学上正确的和与非电子显示不平等（例如教科书和黑板代表）一致的不等式的显示，以加强传统的教学方法并帮助学生或用户容易地看到和理解涉及的数学概念。本发明的显示方法对于典型的手持计算机和计算器的小型，低分辨率显示器特别有用。

摘要： A handheld calculator with disable/re-enable capability. The calculator includes a keypad, a display screen, and circuitry internal to the calculator. The circuitry includes a microprocessor, a storage unit for storing data and programs for execution by the microprocessor to implement calculator functions. The storage unit has stored therein a disable/re-enable program that recognizes a first predetermined calculator event and in response thereto disables one or more programs, and that recognizes a second predetermined calculator event and in response thereto re-enables the disabled program. The invention allows Apps, programs and additional information that may be embedded within the Apps and programs in a calculator or other handheld calculating device to be rendered temporarily inaccessible within a relatively short period of time, and then to be restored to the calculator, again, in a relatively short period of time.
摘要翻译：具有禁用/重新启用功能的手持计算器。计算器包括键盘，显示屏和计算器内部的电路。电路包括微处理器，用于存储用于由微处理器执行以实现计算器功能的数据和程序的存储单元。存储单元在其中存储有识别第一预定计算器事件的禁用/重新启用程序，并且响应于此禁用一个或多个程序，并且识别第二预定计算器事件，并响应于此，重新启用禁用的程序。本发明允许在计算器或其他手持式计算设备中嵌入应用程序和程序内的应用程序，程序和附加信息在相对短的时间段内暂时不可访问，然后再次恢复到计算器，在相对较短的时间内。
