41

First multiply # - xx ( -5) # working from left to right.
Remember PEMDAS (a good way to remember this is: "If you get hurt in PE call an MD ASap")

So the first thing to do is remove parentheses by multiplying .

# 8 - (-5)- 4(-7)#

#rArr8 +5 - 4 xx ( -7) #

Continue multiplying across the parentheses # 4 xx (-7 ) #

# 8 + 5 - 4 xx (-7)#

#rArr8 + 5 + 28 #

Now go to Addition and Subtraction (ASap) working from left to right.

# 8 + 5 + 28#

#rArr 13 +28 #

#rArr 41 #
