First, type a bracket 1 at the end of the quoted sentence. After it is selected, click Right Click-Font to see the superscript in the effect box. After checking, click "OK" to finish the corner marking of the paper.
In addition, formula numbers are often used in this paper. Let's see how it works.
After inserting the formula in the paper, you can choose to insert the number manually and number it according to the chapter and order where the formula is located. You can also use Word for automatic numbering, put the formula on a separate line, move the cursor behind the formula, click Reference-Insert caption, select the formula in the caption box that pops up, and then click OK to finish.
When Word automatically numbers formulas, deleting or modifying the number of one formula will change the number of other formulas, which saves a lot of time.
The above are all about how to make a good corner mark of paper, I hope it will help you.
