What is the smallest number that can be formed using the digits 3,8,2,0,1,5,7 and 6

To find the smallest number that can be formed using the given digits without repeating any of them, you need to arrange the digits in ascending order.

Here are the steps to solve it:

1. Start by looking for the smallest digit among the given digits, which is 0 in this case.
2. Place the smallest digit, 0, as the first digit of the number.
3. Now, look for the next smallest digit among the remaining digits, which is 1.
4. Place 1 as the second digit of the number.
5. Repeat this process for the remaining digits, sorting them from smallest to largest: 2, 3, 4, 5, and 9.
6. Arrange these digits in ascending order to get the smallest possible number: 0, 1, 2, 3, 4, 5, and 9.
7. Therefore, the smallest number that can be formed using the given digits without repeating any of them is 0123459.

So, the smallest number is 0123459.
