Thanks for your insight. I didn't know about subtract and when the second solution is kind of obscure to me it seems very cool and short.

Since - is both subtraction and unary minus one can’t use a right-section like (-1), but considering that subtracting is the same as adding a negative number the slightly obscure form makes sense. I’d still use subtract though.
