— 8 as the digit with the lowest value
— an even number in the thousands column
What number did Craig make?

Answer 1

[AI-generated answer — Bot GPT-4o]

To solve this, we need to arrange the digits 5, 2, 8, and 1 to form a number that meets the following conditions:

- The digit '1' must be in the hundreds place.
- The digit '8' must be in the units or ones place (since it has the lowest value in this context).
- The number must be even, which means the units place should contain an even number (and considering '8' was indicated as the lowest value, it fits this condition).

We have the digits: 5, 2, 1 to place in the remaining positions: thousands and tens, while 8 will occupy the units place and 1 will be in the hundreds place.

Let's start iterating based on these constraints:
1. The thousand's place must contain an even number, and we only have digit 2 available for this spot because it is even.
2. The hundreds place has the digit '1' as specified.
3. We are left with 5 for the tens place, since 8 goes to the units place.

Following these steps, we place:
- 2 in the thousands place
- 1 in the hundreds place
- 5 in the tens place
- 8 in the units place

Putting it all together, the number Craig makes is \(2158\).
