First, let's solve the subtraction (in parentheses):
[tex]\mathsf{\dfrac{-8\left(2-6\right)}{2}}[/tex]
[tex]\mathsf{\dfrac{-8(-4)}{2}}[/tex]
Now, let's solve the multiplication. Remember: in multiplication, two negative numbers will give a positive number:
[tex]\mathsf{\dfrac{-8(-4)}{2}}[/tex]
[tex]\mathsf{\dfrac{32}{2}}[/tex]
Finally, let's solve the division:
[tex]\mathsf{\dfrac{32}{2} = 16}[/tex]
