Without repeating any, 1234, 1243, 1324, 1342, 1423, 1432, 2134, 2143, 2314, 2341, 2413, 2431, 3124, 3142, 3214, 3241, 3412, 3421, 4321, 4312, 4213, 4231, 4123, 4132
To form a 3-digit number using the digits 1, 3, and 5, where each digit is used only once, we can arrange these three digits in different orders. The number of different arrangements of 3 digits is calculated as 3! (3 factorial), which is 3 × 2 × 1 = 6. Therefore, a total of 6 different 3-digit numbers can be formed using the digits 1, 3, and 5.
It is the place value of the first non-zero digit in the number.
470, for one.
The largest number containing the digits 0, 2, 4, 6, and 9 without any digit repeated is 96420. This arrangement places the digits in descending order, starting with the highest digit, 9, and ensuring that each digit appears only once.

Since 10 is a 2-digit number, it is necessary to find the numbers of combinations containing it and not containing it separately.There are 456 combinations containing 10 and 381 not containing it, making 837 in all.

The largest number containing the digits 0, 2, 4, 6, and 9 without any digit repeated is 96420. This arrangement places the digits in descending order, starting with the highest digit, 9, and ensuring that each digit appears only once.
There is no such number. If there was one, simply add another digit at the end and you will have a larger number.
