There are 90 two-digit numbers possible. The first digit can range from 1 to 9 (9 options), while the second digit can range from 0 to 9 (10 options). Therefore, the total number of two-digit numbers is 9 (first digit) multiplied by 10 (second digit), which equals 90.

To form a two-digit number using the digits 0-9 without repetition, the first digit (the tens place) can be any digit from 1 to 9 (9 options), since a two-digit number cannot start with 0. The second digit (the units place) can then be any of the remaining 9 digits (including 0 but excluding the first digit). Therefore, the total number of two-digit numbers that can be formed is 9 (choices for the first digit) multiplied by 9 (choices for the second digit), resulting in 81 possible two-digit numbers.
