Is -n always, sometimes, or never a positive number? Explain. I don't know what they mean by -n - is a negative number?

I am thinking it means negative number. So if it was asking what the absolute value of a negative number was it would always be a positive number. Correct?
so the answer would be sometimes and the explanation would be a negative number would be a positive number if it was asking for its absolute value
Think of -n as (-1)(n)
so it depends on the value of n
if n is positive, then -n is negative.
if n is negative, then -n is positive
e.g.
if n = 5 , -n = -5 , the opposite
if n = -5, then -n = -(-5) = +5
so it depends on the value of n
if n is positive, then -n is negative.
if n is negative, then -n is positive
e.g.
if n = 5 , -n = -5 , the opposite
if n = -5, then -n = -(-5) = +5
Is n always sometimes or never a positive number
