 ## Superscript, subscript and special symbols
 
-Superscript and subscript notation are not normal markdown, but are supported in Rocky Linux documentation via the HTML tags used for the same purpose. Superscript places text entered between the tags slightly above the normal text, while subscript places the text slightly below. Superscript is by far the more commonly used of these two in writing. Some special characters already appear in superscript without adding the tags, but you can also combine the tag to change the orientation of those characters as seen with the copyright symbol below.

+Superscript and subscript notation are supported in Rocky Linux documentation by use of the `^` for superscript and `~` for subscript. Superscript places text entered between the tags slightly above the normal text, while subscript places the text slightly below. Superscript is by far the more commonly used of these two in writing. Some special characters already appear in superscript without adding the tags, but you can also combine the tag to change the orientation of those characters as seen with the copyright symbol below. You can use superscript to:
 
-* represent ordinal numbers, such as 1<sup>st</sup>, 2<sup>nd</sup>, 3<sup>rd</sup>
-* copyright and trademark symbols, like <sup>&copy;</sup>, <sup>TM</sup>, or &trade;, &reg;
-* as notation for references, such as this<sup>1</sup>, this<sup>2</sup> and this<sup>3</sup>
+* represent ordinal numbers, such as 1^st^, 2^nd^, 3^rd^
+* copyright and trademark symbols, like ^&copy;^, ^TM^, or ^&trade;^, ^&reg;&^
+* as notation for references, such as this^1^, this^2^ and this^3^
 
 Some of the special characters, such as &copy; are not normally superscript, while others such as &trade;, are.
 
 Here is how all the above looks in your markdown code:

 Some of the special characters, such as &copy; are not normally superscript, while others such as &trade;, are.

-As you can see, to force superscript you can use the supported HTML tags of `<sup></sup>`.
+To force superscript you surround what you want superscript with `^`.
 
-Enter subscript with the `<sub></sub>` tags, and as noted earlier, is not <sub>used nearly as much</sub> in writing.

 ### Superscript for references

If you only have a single source, you may wish to include it in your conclusion as a single link, but if you have multiples<sup>1</sup>, you can use superscript to note them in your text<sup>2</sup> and then list them at the end of your document. Note that the positioning of references should come after the "Conclusion" section.
