Your task is to use your intelligence to find the values ​​of the two letters E and D accurately, following the pattern of the numbered cells.

What are the values ​​of E and D?

Finding the answer is not simple at all; hidden within the numbered boxes are extremely complex underlying patterns. Think carefully, discover the pattern of the numbers, and choose the appropriate digits. Hint: The values ​​of E and D consist of 4 digits and are less than 2,500.
