For some reason I have lost all orientation in my head apparently with Order of Operations. Everyone knows PEMDAS. Parenthesis , Exponents, Multiplying, Division, Addition, then Subtraction. YET when I do the following problem in that manner I get the wrong answer.

I am really not understanding this so using this exact problem could someone write out exactly what they do first and as they solve the problem every single step you use. Thank you very very much

$\displaystyle 9 + 16 / (-4) * 8 + 3 * 5 $

I'm really at a loss for why I am getting this wrong.

I first did multiplication obviously being the first we see here in PEMDAS.

Multiplied -4 and 8 .. then 3 and 5. Then when those two answers pulled down I divided using the divisor sign, then finished up with the addition then subtraction but -4 is not the right answer

can someone please help me here

[EDITED ADDED] Also could someone please help me with this:

$\displaystyle (x + 3)^2 .. $

In that would the answer be

$\displaystyle x^2 + 6 $ or $\displaystyle x^2 + 9 $

I don't know if the rule for multiplying stands true for whole numbers too (Constants)

Just which one of those is right anyone?
