How many number of combinations can be formed by using numbers123456 within 500?
To find the number of combinations of the digits 1, 2, 3, 4, 5, and 6 that form numbers less than 500, we can consider the constraints based on the first digit. If the first digit is 1, 2, or 3, all combinations of the remaining digits can be used. If the first digit is 4, only combinations that result in a two-digit number can be formed. The total combinations can be calculated based on these conditions, but generally, you can form various 1-digit, 2-digit, and 3-digit numbers, totaling around 120 distinct combinations.
