Hi. My name is Dedhert.Jr. I am a new editor here. My duty, joining Wikipedia, is to contribute to Wikipedia, but I have no clue where I should start. Please warn me if I made some mistake, and with the warning notification that I received from you, I will try to be more careful to act and contribute here. I also want to join WikiProject, but it could be a problem for me if my language is extremely abysmal^[a] and lack knowledge of the subject. Because of these problems, I might never become a good editor, so I personally made up my mind to improve them both.

My favorite subject is mathematics, and I love to make some improvements to the articles, especially to become GA, FA, or FL. The following is my improvement of the article that has GA status:

Square pyramid

The DYKs:

"... that square pyramids can have different shapes, and pyramidologists have put forward multiple theories on which of these shapes was used for the Egyptian pyramids?"

Some of my tools here:

Some lists

Whenever I feel bored, I sometimes come to the Category:GA-Class mathematics articles and Category:FA-Class mathematics articles, checking if there is an update of the significant number of GA. All of these articles may listed in the following specific sections.

GA
