The anwser to the problem is C.
P: parenthesis
E: exponents
MD: multiplication or division (whichever comes first left to right)
AS: addition or subtraction (whichever comes first left to right)
This is the order of operations. We will use this to solve the equation correctly.
We will start with the parenthesis. 2x3=6.
[18/6]x4
Next, we will do the rest of the parenthesis.
18/6=3.
This gets rid of the parenthesis (or brackets.) We will now do the rest of the problem, which is multiplying 3 and 4.
3x4=12.
12 is your final answer.
5 because it says 11-16 which is one number before 15. dollars
-√5/2+√5+1
-√5/2+2√5/2+1
√5/2+1
(√5+2)/2
First you add 11+4 which equals 15 then you add 15+9 which equals 24. So Sandra sees 24 flags
