Let's solve it a step at a time.

For the first digit, how many choices do you have? 9

You can choose 1..9 but not 0, so that's nine choices for the most significant digit.

For the second digit, how many choices do you have? 10

It can be 0..9.

For the third digit, you also have 10 choices.

Choosing one digit doesn't limit your choices for other digits and mirrored numbers (e.g. 123 and 321) are different, so all choices make a unique number.

So the total is the product of our three choices: 9x10x10
