Don’t lose your marbles. Suppose you have infinitely many large boxes (one for each natural number). In each box, you have infinitely many marbles (one for each natural number)—so the boxes are really big! Does the set of all marbles have the same cardinality as the set of natural numbers? Just make a guess and explain why you guessed what you guessed (you need not justify your answer rigorously).
