Difference between the largest and smallest 4-digit numbers

To find the difference between the largest and smallest 4-digit numbers, we need to determine the maximum and minimum 4-digit numbers.

The largest 4-digit number is formed by using the largest digit 9 in each place value. The largest digit 9 is used at thousands, hundreds, tens, and units place. Therefore, the largest 4-digit number is 9,999.

The smallest 4-digit number is formed by using the smallest non-zero digit 1 in the thousands place and the smallest digit 0 in the hundreds, tens, and units place. Therefore, the smallest 4-digit number is 1,000.

Now, we can calculate the difference between the largest and smallest 4-digit numbers.

Difference = Largest 4-digit number - Smallest 4-digit number
Difference = 9,999 - 1,000
Difference = 8,999

Therefore, the correct answer is option 'A' which is 8,999.

Explanation:
- The largest 4-digit number is formed by using the largest digit 9 in each place value.
- The smallest 4-digit number is formed by using the smallest non-zero digit 1 in the thousands place and the smallest digit 0 in the hundreds, tens, and units place.
- The difference between the largest and smallest 4-digit numbers is obtained by subtracting the smallest number from the largest number.
- In this case, the difference is 8,999.
