It depends on the question, but if the question is, how many is there....
It usually means to <u><em>add</em></u>
(What is the question anyway?)
I'll use subscript notation for brevity, i.e. 
.
By the chain rule,
We have
and
When 
, we have
and the partial derivatives take on values of
So we end up with
