10
The set of two-digit number
There is no THE two-digit natural number because there are many of them. 10, 11, 12, .. 99 are all 2-digit natural numbers.
99
2 is the smallest prime number. 11 and 97 are the least and greatest two-digit prime numbers.
2000.The smallest four-digit number there can be is 1000. So, add 1000 and 1000 to get 2000, then least sum you can get when adding two four-digit numbers.
