If you just want to sort the page numbers, but the first page is not clear, then check "Just don't show the page numbers on the first page" in the inserted page numbers.

(PS: I believe that the problem you encountered should not be that simple, it should be what I said below! )

You probably mean that the first page is not displayed, or the first three pages are sorted by Arabic numerals, which page or other symbols follow. At this time, you can use my following methods:

1. If you edit any page at will. First, put the cursor after the last character of the previous page to be edited (for example, if you want to edit the page from the second page, put the cursor after the last character of the first page), then click Delimiter in the Insert menu bar to open the Delimiter dialog box, and then click Next page in the section break type to confirm. Then click Header and Footer in the View menu bar. No dialog box will appear at this time, but the cursor has reached the header. If your page numbers need to be arranged in the footer, you need to click the toggle button in the header footer toolbar that pops up. Don't rush to enter the page number, click the "Connect to Previous Page" button first (some display this button may be "Same as before"). Then you can enter the page number, and it is successful. Then you can do this analogy. (This method is suitable for people with odd page numbers or people who need to input different characters. )

2, if you start from the first page, but there is no sequential or the same type of page number. First of all, it is different from the first case. You need to put the cursor before the first character on the first page, and then click the separator in the Insert Menu Bar. At this point, the separator dialog box appears, and then click Next in section break Type to confirm. Then click "Header and Footer" in the menu bar of the view. If your page numbers need to be arranged in the footer, you need to click the switch button of header and footer on the pop-up "Header and Footer" toolbar. Don't rush to enter the page number, click the "Connect to Previous Page" button first. Then you can enter the page number, and it is successful. But when you edit the second page number, you can't put the cursor on the first character of the page number you want to edit. You just need to follow the practice of "1". (PS: In fact, imagine that there is another one in front of your real first page, so putting your cursor in front of the first page is equivalent to putting it on the last character of the imaginary first page. So this situation is the same as "1,")

In fact, when I first encountered this kind of problem, I was helping others to arrange papers. I searched the answer online, but I couldn't find it for two hours. Although he wrote it like this, it was very simple, so I still didn't understand it myself. Finally, I groped for it myself and tried again and again. This is my practical experience, I hope I can help you. I came out word by word!
