The least 4-digit number you can make with the digits 4, 7, 6, and 0 is 4067. To form the smallest number, you should start with the smallest non-zero digit, which is 4, followed by the next smallest digits arranged in ascending order.
It could be: 4760 = 1
0
To make a number divisible by 10, its last digit must be 0. The last digit of 23483 is 3. Therefore, to make it divisible by 10, you should subtract 3 from 23483. This means the least number that should be subtracted is 3.

1234
Since the 1-digit number is explicitly required to be positive but the 2-digit number is not so constrained, the obvious solution is to make the 2-digit number negative. This gives 9*(-99) = -891
