hi try this: sample: using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace ConsoleApplication1 { class Class2 { static void Main(string[] args) { Console.WriteLine(Enter a number); int numberFloor = Convert.ToInt32(Console.ReadLine()); decimal a = (decimal)numberFloor / 3; decimal res = Math.Round(a); int heightGroupBox = ((Convert.ToInt32(res)* 25) + 30); Console.WriteLine(heightGroupBox); Console.ReadKey(); } } } if you want to write it in a single line try this: int heightGroupBox = ((Convert.ToInt32(Math.Round((decimal)numberFloor / 3)) * 25) + 30);

Perform the calculation using double arithmetic (change 3 to 3.0) and then use the Math.Ceiling method: int heightGroupBox = (int)Math.Ceiling(numberFloor / 3.0) * 25 + 30;
