Question

Using every digit from 0−9 exactly once, make two five-digit numbers such that their sum is as large as possible. What is the sum?

Answer 1

97,531+86,420=183,951

Explanation:

Answer 2

183,951

Explanation:

Each of the 5 digit numbers would have to start with the two largest digits (9&8). The next two digits would have to be the next two largest digits (7&6). Continuing that pattern, we get:

97531+86420=183,951
