I’d like to explicitly understand the difference between the functions of Math.Floor() and Math.Ceiling().

have you checked the documentation of both functions? Floor will always round down, while Ceiling will always round up.

Lesson is saying this is not correct and prompts me: “Did you use Math.Max(numberOne, numberTwo) inside Console.WriteLine() ?”

On my end the code is working just fine, just trying to figure out why the website deems it incorrect.

// Find the larger number between numberOne and numberTwo

  Console.WriteLine(Math.Max(numberOne , numberTwo));

if the lesson uses regex for validation, try without a space between numberOne and ,

Turns out that was correct. Is there a reason for that particular syntax? Trying to maintain good coding habits going forward.

The exercise is a bit strict in its validation, but I would use one consistent way on how to use comma’s and spaces
