Work through PEDMAS to get to
#-3#

Let's start with the original expression:

#3xx2-(8+1)#

And now let's work our way through PEDMAS. First off, P (parentheses). We have one of those so let's do the math inside of it:

#3xx2-(9)#

Next we have 2 multiplications: #3xx2# and #(-1)xx(9)#. Let's do those:

#6-9#

Which gets us to:

#-3#
