Calculator not returning decimal values?

[QuestionPlease]

My calculator is not returning decimal values for example if I do 2.2 + 2.2 the answer it returns is 44 instead of 4.4??
What did I do wrong???
Here's my Code

namespace CalcW
{
    public class Calculator
    {
        

        public decimal CurrentValue { get; set;}
        
        private decimal First{get;set;}
        private decimal Second{get;set;}
      
        

       

        public void EnterValue(decimal value, bool n )
        {
            if (n)
            {
                First = value;
            }
            else
            {
                Second=value;
            }
            
        }

        public void Add()
        {
            CurrentValue = First + Second;
            //CurrentValue + value;
        }

        public void Subtract()
        {
            CurrentValue = First - Second;
            //CurrentValue - value;
        }

        public void Multiple()
        {
            CurrentValue = First * Second;
            //CurrentValue * value;
        }

        public void Divide()
        {
            CurrentValue =First/Second;
            //CurrentValue /= value;
        }

        public decimal Equals(decimal value, string sn)
        {
            this.EnterValue(value, false);

            switch(sn)
            {
                case "+/-": Reciprocal(); break;
                case "+": Add(); break;
                case "-": Subtract(); break;
                case "*": Multiple(); break;
                case "/": Divide(); break;
                case "sqrt": SquareRoot(); break;
                case "1/x": Fraction(); break;

            }
            First = 0;
            Second = 0;
            return CurrentValue;
        }

        public void Reciprocal()
        {
            CurrentValue =First *(-1);
        }

        public void SquareRoot()
        {
           
        }

        public void Clear()
        {
            CurrentValue = 0;
        }

        public void Fraction()
        {
            CurrentValue = 1/First;
        }
       
    }
}
