C# Operators and Math

ExampleC#

using System;

class Program
{
    static void Main()
    {
        int a = 17, b = 5;
        Console.WriteLine(a + b);
        Console.WriteLine(a / b);
        Console.WriteLine(a % b);
        Console.WriteLine((double)a / b > 3);
        Console.WriteLine(a > b && b > 0);

        int x = 10;
        x += 5;
        x++;
        Console.WriteLine(x);
        Console.WriteLine(Math.Max(3, 9));
        Console.WriteLine(Math.Abs(-5));
        Console.WriteLine(Math.Pow(2, 10));
    }
}

As in Java and C, dividing two integers gives an integer: 17 / 5 is 3. Cast one side to double to keep decimals.
