- First Digit:
- Choices: 9 (digits 1 through 9)
- Representation: 9
- Remaining 8 Digits:
- After choosing the first digit, there are 9 remaining digits (including zero) to choose from, but each subsequent digit must be unique.
- The number of ways to arrange these 8 digits is represented by 9 factorial, written as 9!
Combining the Choices
- Total Number of 9-Digit Numbers with All Different Digits:To find the total number of unique 9-digit numbers, multiply the number of choices for the first digit by the number of ways to arrange the remaining digits.Total Ways = 9 × 9!
