If you have four cards with the numbers 1,2,3 and 4 how many numbers can you make that are bigger than 2200?
Sorry about that. You didn't mention it in the question. heureka's answer is correct.
Hi! Thanks for the answer I really do appreciate it but if you can only use each number once how many would that be?

You can make 16 numbers that are bigger than 2200
Ah I see thanks! Drawing it out helps but do you maybe also know a more convenient way to calculate this when I have a lot of numbers?
My attempt:
4!−8=24−8=16
I get it thanks!! :"D
I think so: 4! - 3! - 2! =24 - 6 - 2 =16
Thanks I understand it now! :D
