Excellent Student

I have today - 26.3.2020, seen a comment from a friend and he confirms using this in his coding of jobs submitted. The following is what I wrote in July 2012 I have not received any comment or e-mail from anyone. Does it mean that what I have written is clear enough for everyone? I am not sure and therefore I’ll give another example. I hope someone will start commenting so that I can move forward. Let me give another example: 

Mathematics I do not know who to attribute all the various methods of doing mathematics which I am going to write on from today.   One of the earliest books to be written about these methods was written by Jakow Trachtenberg. He was a Russian who was born in 1888 and died in 1953.Subsequently many others have changed a little here and there and called it their own. All I can say is that I learnt all these as I was growing up and none of it is my own and now I share them with you.
