I am having a problem answering a question, and i need to know what does the parenthesis mean when next to each othe EX. -5+(-9)(2+4) does it mean to multiply or what? please help
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
Well first simplify the parenthesis then multiply and finally subtract. You don't do $\displaystyle 5-9$ you do $\displaystyle -9(4 + 2)$ and then do $\displaystyle -5 + (-54)$ What you said didn't come out to clear amber.
Remember to follow PEMDAS
Sorry for the double post:
Amber according to PEMDAS multiplication comes before addition remember:
Parenthesis $\displaystyle (4+2)=(6)$
Exponents
Multiplication $\displaystyle -9 \cdot 6 = -54$
Division
Addition $\displaystyle -5+(-54)$ or $\displaystyle -5-54$ 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
