I write articles on many subjects including mathematics, history, plot summaries, chess, gambling, science, poetry, etc.
I have a Bachelor of Science in Mathematics and a Classical Studies Minor. I wrote How to Prove The Collatz Conjecture and Many Articles on Many Subjects, I have written several sonnets. I can write an article of about 500 to 1000 words in seven days after the order is accepted for four dollars. I can probably write more articles in seven days, but it all depends on other circumstances.
