Example of operators

        int result = 1 + 2; // addition
        result = result - 1; // subtraction
        result = result * 10; // multiplication
        result = result / 5; // division
        result = result % 3; // modulus

Abbreviating of operators

        // result = result + 1;
        result++;

        // result = result - 1;
        result--;

        // result = result + 2;
        result += 2;

        // result = result * 10;
        result *= 10;

        // result = result / 3;
        result /= 3;

        // result = result % 2;
        result %= 2;
