The article at User:Matheosharison/Sandbox will need a lot of work before it can go into the main space for example:
- extra spaces after a comma
- starting sentences are with a capital letter
- Capitalization for headings
- double periods (.. , ...) - need to be deleted
- Possibly other things
And writing style needs to be fixed for the entire article after that. After you are done with the text of the article and putting in what you want to put in, can you make the above fixes you can and then we can put it in out to-do list to fix the rest?
