# Simple 5 operator calculator in C#

The program takes 2 decimals as input and an operator (+, -, *, /, ^) so far. Any suggestions to make this code cleaner or shorter?

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

namespace Calculator
{
class Program
{
static void Main(string() args)
{
Console.Write("Enter a number: ");

Console.Write("Enter an operator: ");

Console.Write("Enter a number: ");

if (op == "+")
{
Console.WriteLine(Sum(n1, n2));
}

else if (op == "-")
{
Console.WriteLine(Dif(n1, n2));
}

else if (op == "*")
{
Console.WriteLine(Prod(n1, n2));
}

else if (op == "/")
{
Console.WriteLine(Div(n1, n2));
}

else if (op == "^")
{
Console.WriteLine(Pow(n1, n2));
}

else
{
Console.WriteLine("Invalid Operator! Only '+', '-', '*', '/', or '^' allowed.");
}
}

static Decimal Sum(Decimal n1, Decimal n2)
{
Decimal sum;
sum = n1 + n2;
return sum;
}

static Decimal Dif(Decimal n1, Decimal n2)
{
Decimal dif;
dif = n1 - n2;
return dif;
}

static Decimal Prod(Decimal n1, Decimal n2)
{
Decimal prod;
prod = n1 * n2;
return prod;
}

static Decimal Div(Decimal n1, Decimal n2)
{
Decimal div;
div = n1 / n2;
return div;
}

static Decimal Pow(Decimal n1, Decimal n2)
{
Decimal pow;
pow = (decimal)Math.Pow((double)n1, (double)n2);
return pow;
}
}
}
