Mathematical Calculation Exercise

The parameter description for generating a copybook is as follows:

1. Page Settings : Set the parameters related to the copybook page, this set of parameters is mandatory.
   1. Paper : Choose the paper size for the copybook. This tool has built-in A3, A4, A5, A6, and B4, B5, and B6 paper sizes. You can also select to customize the paper size.
   2. Width, Height : The width and height of a paper page, in millimeters (mm), with values ranging from [50,1000].
   3. Margin : The margin of the paper, in millimeters (mm). Fill in a numerical value and use the same page margin for the four edges. Fill in four numerical values separated by commas, and the corresponding order is top, right, bottom, and left. The range of values is [0,100].
   4. Background : The background of the copybook paper supports both none and colors.
   5. Fg Color : The color of the copybook grid.
   6. Print Delay : Print waiting time, in seconds, with a range of [3600]. If you find that when printing, the font of the copybook is not the font selected when generating the copybook, Or if the title display of the copybook is misaligned, please increase this time to wait for the font to load when printing. When it is necessary to increase the printing waiting time, it is recommended to set it to 120, which means waiting for 2 minutes to load the font before printing.
2. Head-Foot : Set the header and footer content of the copybook page, and this set of parameters is optional.
   1. Main Title : The main title displayed on each page of the copybook is larger in font size.
   2. Header : The title displayed in the header of the copybook, with a medium font size and support for multiple sets of header titles. The header content format is[Content] . For example [Name][Class][   Year   Month   Day].
   3. Footer : The title displayed at the end of the copybook page is of medium font size. The footer content format is [Content] . For example [${currentPage} / ${totalPage}]. Among them ${currentPage} is a placeholder for the current page, ${totalPage} is a placeholder for the total page.
3. Exercise Settings : Generate parameters related to addition, subtraction, multiplication, and division exercises, which are mandatory parameters.
   1. Count : Support specifying the number of generated addition, subtraction, multiplication, and division exercises separately. The number of individual exercises cannot exceed 500, and the total number of exercises cannot exceed 500.
   2. N1 Range : The numerical range of the first digit participating in the operation, which supports filling in the range of [0,10000].
   3. N2 Range : The numerical range of the second digit participating in the operation, which supports filling in the range of [0,10000].
   4. Position : In the exercise questions, the position of the numbers to be filled in supports multiple options such as operand 1, operand 2, result, random, etc.
   5. Font Size : The font size of the generated math exercise questions. The range is [1,100].
   6. Col/Row : How many exercises are displayed in each row. The range is [1,10].
   7. Row/Page : How many exercises are displayed on each page. The range is [1,100].
   8. In the exercises, subtraction does not result in negative numbers, and division does not result in decimals.
   9. In the generated math exercise questions, the first half is the exercise question, and the second half is the answer.
4. Print : Print the generated copybook as a PDF file or use a printer to print the copybook. The printing precautions are as follows (using Chrome browser as an example):
   1. In the pop-up print window, select the correct paper size specification for more settings. Ensure that the size of the printed paper is consistent with the size of the generated copybook.
   2. In more settings,Marginsselect None.
