Question

Answer

Explanation:

To find the sum of the greatest and smallest 4-digit numbers, we need to determine what those numbers are first.

Finding the greatest 4-digit number:
The greatest 4-digit number would have the digit 9 in the thousands, hundreds, and tens places, and the digit 9 in the units place. Therefore, the greatest 4-digit number is 9999.

Finding the smallest 4-digit number:
The smallest 4-digit number would have the digit 1 in the thousands place, and the digit 0 in the hundreds, tens, and units places. Therefore, the smallest 4-digit number is 1000.

Calculating the sum:
To find the sum of the greatest and smallest 4-digit numbers, we can simply add them together:

9999
+1000
------
10999

Therefore, the sum of the greatest and smallest 4-digit numbers is 10999.

Answer:
The correct answer is option B, 10999.
