What is the sum of all positive integers? To clarify: what do you get if you add all the positive full numbers?
1 + 2 + 3 + 4 + 5 + ... + to infinity?
The answer is, of course, in the Internet. What isn't?
Please choose an answer from the list of options. And if interested, look it up on the internet.
Do not post the answer as a comment - until after several days, at least. I'll return to this question after several days and I will respond to some of the comments - if any. I'll also post an answer to the question.
Unlike my previous quizzes in this "Random, silly, fun" category, this question has a definitive answer. (My previous quizzes were "thought experiments" and any answer to them is valid.)
Also based on feedback in my other quizzes, I've added 2 "out" options.
