Question from Justin, a student: Hi there, I was wondering does +infinity=+infinity in the extended real number system? Basically, I was wondering does +infinity=+infinity since -infinity and any extended real number (except +infinity) are less than +infinity? Thank you sooo much for any help and thoughtful insights you can provide for this question! Sincerely, Justin |
Yes; while adding infinite elements to the reals requires various operations to be restricted, the equality relation behaves normally.
Good Hunting!
