The parentheses around the -9 is just around it to seperate it and show that it is negative. You do not multiply the -9 and -5 but you multiply the sums of
-5+-9 and 2+4 which would be, -14+6=-8
Sorry for the double post:
Amber according to PEMDAS multiplication comes before addition remember:
Parenthesis
Exponents
Multiplication
Division
Addition or Sorry for that mistake in my original post.
Subtraction
yes, parenthesis means you multiply. HOWEVER, you do the stuff inside the parenthesis FIRST. remember BEDMAS (it's the order to do the question in):
B=brackets
E=exponents
D=division
M=multiplication
A=addition
S=subtraction
so in your example, the steps are:
-5+(-9)(2+4)
-5+(-9)(6)
-5+(-54)
-5-54
=-59
