That's because you are still not clear about the distinction between a
number and its representation. If you have Number values (that's an
ECMAScrip type) then arithmetic is the correct way to produce new
numbers like this.

Don't make you code worse by adding yet more function that communicate
via globals. This operation is a self-contained function of the array.
Pass the array as a parameter and return the result from the function.
