I am skeptical about the answer.
I first eliminated the common terms in each Quantity which were ( -58 to -36). Therefore,
For Quantity A :
we will have terms from ( -87 to -59), we need to know is it + or negative.
87-59+1= 29 terms. So, the answer will be -ve.
For Quantity B:
We will be left with -34 x -35. The answer is +ve.
So, quantity B is greater.
may someone elaborate ?

Number of integers from m to n inclusive is
\(n-m+1\)
\(-36-(-87)+1=52 \) even numbers so positive the multiplication regardless the number is
\(-34-(-58)+1=25\) odd numbers so we will have a negative number regardless the value of the multiplication of the numbers themselves
A > B
hope this helps
