Write the number with the least value using the digits 1 through 9 use each digit once explain your reasoning?

Answer 1

To create the smallest number using the digits 1 through 9, we should arrange the digits in ascending order. This is because placing smaller digits in the higher place values results in a smaller overall number.

Here's how you can do it:

List the digits in ascending order: 1, 2, 3, 4, 5, 6, 7, 8, 9.

Combine them to form the number: 123456789.

This number has the least value because it starts with the smallest digit (1) in the highest place value 1, followed by the next smallest digits in order. Using any other arrangement would result in a larger number.
