#-12#

Explanation:

Follow the order of operations - P.E.M.D.A.S

  • Parenthesis
  • Expontent
  • Multiply
  • Divide
  • Add
  • Subtract

So, to begin, simplify or solve anything that's in parenthesis first

Simplify #(16/2)#

#(16/2)=8#

Next is any exponents, but there aren't any, so move onto the next order of operations, which is to multiply

So, multiply #-4(5)#

#-4(5)=-20#

So, now the problem looks like:

#8-20#

After multiplying, you would do any division then addition, but there isn't any. So, just solve the problem

#8-20=-12#
