i'm still pretty new to programming in c# but I gave it a shot, probably over complicated things: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks;

*/

b = Convert.ToInt32(Console.ReadLine());
Console.Write("c: ");
c = Convert.ToInt32(Console.ReadLine());
Console.Write("d: ");
d = Convert.ToInt32(Console.ReadLine());
return a + b + c + d;
