How do you simplify #-12-4+(8xx4)#?

1 Answer

Answer:

16

Explanation:

We'll use the Order of Operations, sometimes known as PEMDAS:

  • #color(red)(P)# - Parentheses (also known as Brackets)
  • #color(blue)(E)# - Exponents
  • #color(green)(M)# - Multiplication
  • #color(green)(D)# - Division (this has the same weight as M and so I gave it the same colour)
  • #color(brown)(A)# - Addition
  • #color(brown)(S)# - Subtraction - (again, same weight as A and so the same colour)

So with #-12-4+(8xx4)# we have a parenthesis:

#-12-4+color(red)((8xx4))#

#-12-4+color(red)((32))#

Now we have addition and subtraction, so we read from left to right and evaluate:

#-16+32#

#16#
