1.App使用教程

「阶乘」「排列数」「组合数」

点击屏幕上的选择器选择对应的参数即可自动完成计算

「行列式」「逆矩阵」「矩阵乘法」

依次在输入框中输入矩阵的所有参数,点击“计算结果”即可完成计算

「多项式除法」

分别输入两个多项式的参数,点击”计算结果“即可完成计算。需注意:除法为上方的多项式除以下方的多项式

2.App使用技巧

对于通过键盘输入参数的模块,可以通过键盘上的回车键或键盘上方的向右指(如下图中的蓝色箭头所指)跳转到下一个输入框,点击键盘放下图标(如下图中的红色箭头所指),则可以放下键盘

对于多项式除法,若某些非最高次项的系数为0,则可以不输入内容,如下图中的红色箭头所指,这些参数将默认为0

1.App usage tutorial

「Factorial」「PermutationNumber」「CombinationNumber」

Click the selector on the screen to select the corresponding parameters to complete the calculation automatically.

「Determinant」「InverseMatrix」「MatrixMultiplication」

Enter all the parameters of the matrix in the input box in turn, and click "Calculation Results" to complete the calculation.

「PolynomialDivision」

Enter the parameters of two polynomials respectively, and click "Calculation Result" to complete the calculation. Note: The division is the upper polynomial divided by the lower polynomial.

2.Tips for using App

For modules that enter parameters through the keyboard, you can jump to the next input box through the Enter key on the keyboard or the right finger above the keyboard (referred to by the blue arrow in the figure below), click the keyboard down icon (referred to the red arrow in the figure below), and then you can put down the keyboard.

For polynomial division, if the coefficient of some non-highest terms is 0, you can not enter the content. As indicated by the red arrow in the figure below, these parameters will default to 0.
