From left to right, pick the smallest possible digit every time. This will give you the smallest possible number.
The smallest four digit number is 1000. It is even so 1001 is the smallest four digit number that is odd.
The smallest even 4-digit number using the digits 5, 7, 4, and 9 is 4579. To create the smallest number, we start by placing the smallest digit, which is 4, in the thousands place to ensure it is a 4-digit number. Since we need to make it an even number, the units place must be an even number, so we use 4. Placing 5 in the hundreds place and 7 in the tens place gives us the smallest even 4-digit number, 4579.

The smallest is 1111 if repeats are allowed. If not, it is 1235.
The smallest 9-digit number that can be formed using the digits from 0 to 9 is 1,234,567,890. However, since we are limited to 9 digits and cannot repeat any digits, the smallest 9-digit number is 1,234,567,89, where '0' is not included, as it would make the number 8 digits long. Therefore, the number is 1,234,567,89.
if u were to use all the numbers as one 4 digit number, the smallest number would be 4579. if u were to add or subtract them, the smallest number would be -17

The smallest possible number you can create using the digits in 123456 and 7, while using each digit only once, is 1,234,567. By arranging the digits in ascending order, you ensure the smallest value, starting with the smallest digit, which is 1, and placing the others in increasing order thereafter.
-7510 is the smallest.
