To form a 3-digit number using the digits 1, 3, and 5, where each digit is used only once, we can arrange these three digits in different orders. The number of different arrangements of 3 digits is calculated as 3! (3 factorial), which is 3 × 2 × 1 = 6. Therefore, a total of 6 different 3-digit numbers can be formed using the digits 1, 3, and 5.
A one digit number is a number with only one number. For example: 12 is a two digit number. It has two numbers. 3 is a one digit number because it only has one number.
