I have to admit, this exercise is in terrible wording, just as stated initially.
Codecadey should maybe consider, that not everyone is a native speaker and explain a little bit more in detail.
The exercise in NO WAY explains how the expected result is related to the task. What relation does the results array in the solution have with the numbers handed in through the arry ‘numbers’?
Sorry, but this was one of the worst lessons so far, very frustrating and totally unclear (b/c of substandard description)
