A. –100
B. –10
C. 0
D. 10
E. 100



Here putting the values of m and n in the above equation we get

=(-5 -5) * (5 + 5)

= -10 * 10
=-100

Explanation

Start by substituting the given values for the variables in the equation.
You’ll be left with (–5 − 5)(5 + 5), which simplifies to (–10)(10), or –100.
