find the difference between the greatest and theleast 6-digit numbers formed by 0 and the first 5 odd numbers.

On the assumption that the smaller number cannot start with zero, the greatest difference is:

975310 - 103579 = ?

I made the first number as large as possible and the second the smallest possible using the given digits.

You can find the numbers that give minimum difference by sing similar logic.

For the minimum difference, you can chose the same number twice and get zero.

To find the difference between the greatest and the least 6-digit numbers formed by 0 and the first 5 odd numbers, we need to determine the greatest and the least 6-digit numbers that can be formed using these digits.

The greatest 6-digit number will have the digit "9" in the hundred thousands place. Since we can only use the digits 0 and the first 5 odd numbers, the other digits can be arranged in descending order, starting from the left, to get the greatest number. So, the greatest 6-digit number will be 95,743.

Similarly, the least 6-digit number will have the digit "1" in the hundred thousands place. Again, arranging the remaining digits in ascending order, we get the least number. So, the least 6-digit number will be 10,357.

To find the difference, we subtract the least number from the greatest number:

95,743 - 10,357 = 85,386

Therefore, the difference between the greatest and the least 6-digit numbers formed by 0 and the first 5 odd numbers is 85,386.
