Take a look into the code I did only for you. Its a code, which allows the user to insert as many numbers and operands as he wants to create a formula.
On the end, when he wants to create an out put, he only inserts the enter after number:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Jan22Calculator
{
    class Program
    {
        static void Main(string[] args)
        {
            bool bEnd = false;
            decimal total = 0M;
            decimal number = 0M;
            string strOperand = null;
            string strFormula = null;
            int counter = 1;

            Console.WriteLine("Calculator: Please enter number by number, seperated by operands.");
            Console.WriteLine("To get the result, simply write the equals sing just after number (X=)");
            do
            {
                string word = GetCounter(counter);              

                Console.WriteLine("Please enter the " + word + " number:");
                string strNumber = Console.ReadLine();

                
                if (strNumber.Contains("="))
                {
                    strNumber = strNumber.Remove(strNumber.Length - 1, 1);
                    bEnd = true;
                }
                bool bChecking = CheckingNumber(strNumber);
                if (bChecking)
                {
                    strFormula += strNumber;
                    counter++;
                    number = Convert.ToDecimal(strNumber);
                    total = GetTotal(number, total, strOperand);

                    bChecking = false;
                    while (!bChecking && !bEnd)
                    {
                        Console.WriteLine("Please enter the operand (+, -, /, *):");
                        strOperand = Console.ReadLine();
                        bChecking = CheckingOperand(strOperand);
                        if (bChecking)
                            strFormula += strOperand;
                        else
                            Console.WriteLine("Wrong operand.");
                    }
                }
                else
                    Console.WriteLine("This is not the number.");
            }
            while (!bEnd);

            //on the end it shows the final result:
            strFormula = strFormula + "=";
            Console.WriteLine("{0}{1}", strFormula, total.ToString());
            Console.ReadLine();
        }

        public static string GetCounter(int counter)
        {
            string word = null;
            string[] words = { "1st", "2nd", "3rd" };
            if (counter < 3)
                word …
