The greatest 5 digit number is 98765. The greatest 5 digit number that doesn't contain any of those digits is 43210. The difference between them is 55555.The two five digit numbers using all ten digits once and only once between them that sum to the largest value are 97531 and 86420. They sum to 183,951 and have a difference of 11111. These two numbers are not unique ... you can switch any pair of digits between the two numbers as long as you keep them in the same position without changing the sum, though this will change the difference.
It is not clear what the question means: there are 31 2-digit numbers that can be expressed as a sum of two squares.
Well, butter my biscuits! The two consecutive 4-digit numbers that add up to 9173 are 4586 and 4587. It's as simple as that, sugar!
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.

Add the two greatest possible four digit numbers. 9999 + 9999

what is the least possible sum of two 4-digit numbers?what is the least possible sum of two 4-digit numbers?
(9,999) + (9,999) = 19,998 So it looks like the sum of two 4-digit numbers can't have more than 5 digits.

There are five such numbers.

In base ten it would be 19998. The sum could be much larger assuming different bases. You need to specify the base.
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.
