数学软件，供学生学习计算前和微积分。 数学中心 2 级包括科学计算器、图形计算器 2D 数字、图形计算器 2D 参数、图形计算器 2D Polar、整数计算器和理性计算器。科学计算器以科学模式工作。 有保存和打印计算历史记录、更改字体和标准编辑选项的选项。图形计算器2D数字是图形计算器2D从数学中心1级进一步发展。它具有扩展功能：添加了双曲函数。还增加了新的功能，允许计算系列，产品系列，排列，组合，牛顿二项系数和高斯二项系数。图形计算器2D数字能够为第一和第二导数、确定积分（曲线下的区域）和长度积分（曲线长度）构建图形。由于这些计算是以数字方式而不是符号计算的，因此计算器称为数字。图形计算器二D参数化是图形计算器二D数字的概括。现在 x 和 y 是参数 tau 上的函数。由于所有计算都执行两次，因此对于 x 和 y，为了保持计算速度，牺牲了精度。因此，尽管可以使用 x=，y=f（）在参数计算器中构建相同的 y=f（x）图形，但图形计算器 2D 数字将更精确地构建它。图形计算器二D极性是图形计算器2D数字的专业化。

终端用户许可协议
1. You may install a copy of the Software on your personal computers. For each paid license you are given five available hardware profiles. One profile is considered as main and four as alternative. Each hardware profile is based on processor. You may install Software either on five computers at once, or install on one computer and keep four available profiles for future use, or in any other combination. Once activated a profiles becomes a used profile and number of available profiles decreases. A used profile cannot be replaced. For example, if a processor on your computer breaks down, you will have one main profile and three alternative profiles. If you have multiple operating systems on your computer, then you may install and activate the Software on each operating system under one profile. You may install and activate the Software on any virtual machine, but it can take an available profile, since virtual machines usually have different information for processor. If you have paid for a license, you may install and activate any past and future version of the Software. A paid license has no time limit. Activation of the Software requires internet connection. Once activated the Software does not require internet connection. 2. You may not reverse engineer, decompile, disassemble or otherwise attempt to discover the source code of the Software. 3. You may not alter or modify the Software or create a new installer for the Software.
