Hello,

My question is less about the Modulo and more about the Console.WriteLine() statement.

In the examples before the “Instructions” the following is written:

int myNum = 85939824;
Console.Write(myNum % 2); // prints 0, so number is even

When doing the “Instructions” I used:

Console.Write(students%groupSize);

which returned the correct result 0, but the error message came up telling me to use Console.WriteLine() instead.

What is the difference between the two?

The second line of code is wrong its meant to be Console.WriteLine(students % groupSize);
You were very close though sorry for late reply.

“You need to find a number that will go evenly into 18 (without a remainder) so that there are an even number of students. The groups should have more than 2 students in each group, but no more than 5.”

There’s a typo - I think it should say no less than 2.
