To find the number of three-digit combinations, we consider the digits from 000 to 999. Each digit can range from 0 to 9, giving us 10 options for each of the three digits. Therefore, the total number of three-digit combinations is (10 \times 10 \times 10 = 1,000).
The sum is 22 times the sum of the three digits.
To form a three-digit number using the digits 0-9, the first digit cannot be 0 (as it would not be a three-digit number). Thus, the first digit can be any of the digits from 1 to 9 (9 options). The second and third digits can each be any digit from 0 to 9 (10 options each). Therefore, the total number of three-digit numbers is (9 \times 10 \times 10 = 900).

If one can repeat digits, each of the three positions in a three-digit password can be filled by any of the 10 digits (0-9). Therefore, the total number of three-digit numerical passwords is (10 \times 10 \times 10 = 1,000). Thus, there are 1,000 possible three-digit numerical passwords when digits can be repeated.
The digits of 345 are 3, 4, and 5. To form a two-digit number, we can choose any of the three digits for the tens place and any of the three digits for the units place. However, since a two-digit number cannot start with 0 and all three digits are non-zero, we can use all three digits. Thus, we have 3 choices for the first digit and 3 choices for the second digit, resulting in (3 \times 3 = 9) two-digit numbers.
To form a three-digit number using the digits 1-7, we can choose any of the 7 digits for each of the three places (hundreds, tens, and units). Therefore, the total number of 3-digit combinations can be calculated as (7 \times 7 \times 7), which equals 343. Thus, there are 343 different three-digit numbers that can be formed using the digits 1-7.
