excalibirr

College Student studying mathematics.

Still just a beginner but eager to learn.

I really love the mathstackexchange website and am eager to work my way up through the ranks both here and in real life mathematics.

I also enjoy many other things in life too. A good book , a good puzzle, a good adventure and good friends.
