What's the largest number you can make with 4 digits? (Don't answer 9999)?

Answer 1

If you allow factorials, you can get infinitely large.
9^9^9^9 is a good try, but why stop there?
(9^9^9^9)! is bigger.
((9^9^9^9)!)! is bigger still.
You can keep adding exclamation marks to get a number as big as you want.

Answer 2

How many different mathematical symbols are we allowed to use?
If none, then 9998, or 9^9^9^9 if ^ doesent count.
But if we can use as many as we want, 9999!!!!!!!!!... (with a lot, or infinite number of factorials, thus the number being infinity).
If only one factorial then 9999!.
I am not sure if 9^9^9^9 or 9999! is larger, but i think it is 9999!

Answer 3

I think here no symbols and characters are allowed. Since the question is simply "What's the largest number you can make with 4 digits?"
So, it should be => 9 to the 9th power of 9th power of 9

Answer 4

Well 9999! would be a pretty large number. It would probably take up to at least one page to type the entire product number.

Answer 5

well, infinity isnt really a digit, so im gonna say 1234 times infinity
if that doesnt work, im gonna have to say 999/0+
thats 999 divided by the smallest possible number above 0
