I need help with an exponentiation problem

I have to solve this:

3h × (-h2 )


When I tried it, I got 3h3 as a result, yet the answer key says it should be -3h3 I don't understand why 3 becomes negative.

My logic was the following: -h2 is the same as h2 (because negative multiplied by negative equals positive). Therefore the problem becomes 3h × (h2 ) and that is the same as 3 × h × h2 We can add the exponents and get h3. Therefore the answer is 3h3. What am I doing wrong?
