Boo Radley is in some ways as mysterious as this question, and for that reason he adds a kind of Gothic quality to Harper Lee's To Kill a Mockingbird.
At the end of To Kill a Mockingbird, Scout suggests that she and Jem have learned quite a bit over the course of the action of the novel, but there is still possibly one more thing for them to learn - algebra.
This is a joke but it also relates to the idea presented in the novel that school is not the only place (and sometimes not the best place) to learn important lessons.
I am not sure what your question has to do with Arthur Radley, so I will just relate some general information about him. Although he is ostracized by the town because of his violent past and unusual family, he turns out to want social contact when he befriends the Finch children. In the end, his intervention saves thier lives, but his life does not change.
