The sum of the greatest and smallest five-digit numbers is 109999 ​ .

Explanation

Identifying the Smallest and Greatest Five-Digit Numbers We need to find the sum of the greatest and the smallest five-digit numbers. The smallest five-digit number is the smallest number that has five digits, which is 10,000. The greatest five-digit number is the largest number that has five digits, which is 99,999.

Calculating the Sum Now, we need to calculate the sum of these two numbers: 10,000 + 99,999.

Performing the Addition Performing the addition, we get: 10000 + 99999 = 109999

Final Answer Therefore, the sum of the greatest and the smallest five-digit numbers is 109,999.


Examples
Understanding place value and number ranges is crucial in many real-life scenarios. For instance, when setting a budget, you need to know the range of possible expenses. If you are planning a large event, knowing the smallest and largest possible number of attendees helps in resource allocation. Similarly, in computer science, understanding the range of numbers that can be stored in a certain number of bits is essential for efficient memory usage. This problem demonstrates a basic understanding of number ranges, which is a fundamental concept in mathematics and its applications.
