Here the first digit can be from $1 - 9$ and the second digit can be from $0 - 9$ but not the first digit $10 - 1 = 9$. And the third digit can be from $0 - 9$ but not the same as the first and second digit. Therefore total number of natural numbers from $1$ to $1000$ without repetition= $648 + 81 + 9 = 738$ ways.
