**ADDITIONAL ASSIGNMENT OPERATOR**

Consider the following statement,

numbers[loop] += 7;

This assignment += is equivalent to add equals. It takes
the value of *numbers[loop]*, adds it by 7, then assigns the
value to *numbers[loop]*. In other words it is the same as,

numbers[loop] = numbers[loop] + 7;
