Add more explanation

Clearly was a typo =p

Okay yea so I'm not sure really what to do here. What is the best way to give the description of this solution? Maybe the answer and a small one 'sentence' explanation?

Agree, it should be the answer plus a small one-sentence explanation. This could happen in the hint or solution.
