C# Errors

Question

Can anyone help? I don't see what's wrong and I don't understand the errors. I think I've gotten too used to Python’s readability. Lol

Answer 1

Variables can only be declared inside a class or method. Move number1, number2, and answer to main().

By the way, those 5 lines at the top of your code are importing other namespaces you can use. Ex: "using System;" allows you to use
Console.WriteLine();
instead of
System.Console.WriteLine();

using System; is all you really need, but you can leave them all.
