class Program
{
    static void Main(string[] args)
    {
        int var1 = 100;
        int sum = 10, sub = 10, mul = 10, div = 1000;

        Console.WriteLine("sum+var1 is " + (sum += var1));
        Console.WriteLine("sub-var1 is " + (sub -= var1));
        Console.WriteLine("mul*var1 is " + (mul *= var1));
        Console.WriteLine("div/var1 is " + (div /= var1));
    }
}

Output

sum+var1 is 110

sub-var1 is -90

mul*var1 is 1000

div/var1 is10
