I remember that! I must be a little older than you, and high school algebra was still fresh in my mind.
Amazing how a multinational corporation can't get simple "order of operations" right!!

Amazing how a multinational corporation can't get simple "order of operations" right!!
Well it wasn't McDonalds fault, it was the 16-17 year old girl working the counter.
Oh I remember how upset I was. I was something simple like 3 x (1+5).
I remember my dad yelling at the manager, but neither he or the manager really knew for sure.
So they finally gave me that cash.
My dad is a real hot head, and I remember he accused the girl of stealing it, and later would give it to her friends to cash in and shit like that. Cause they never even bothered with the skill testing question, when you just won an icecream cone.
if no multiply sign, in this case, 2(9+3), everything that attaches to the bracket has the highest precedence!
And also, multiplication has the highest precedence than division!

Rules
1. Calculations must be done from left to right.
2. Calculations in brackets (parenthesis) are done first. When you have more than one set of brackets, do the inner brackets first.
3. Exponents (or radicals) must be done next.
4. Multiply and divide in the order the operations occur.
5. Add and subtract in the order the operations occur.
48÷2(9+3) = ????
48÷2(12) = ????
24(12) = ????
24 x 12 = 288

Pretty sure that's not correct. Brackets, Exponents, Division/Multiplication, Addition/Subtraction. Division and Multiplication hold the same weight and the order you do them is determined by which comes first in the equation. Same with Addition and Subtraction.

The answer is that it is a very poorly written equation. Due to the fact that it is 2(9+3) it is implied that those two numbers go together and that operation is to be completed before the division. It should never have been written the way it was though. We are all now more stupid for having even read this thread.

The people that voted A don't know their math.
It's pretty clear what mistake people are making though.
48÷2(9+3) = ????
Everyone knows you do the math in brackets first. I believe those people are assuming the 2 before the brackets is part of the bracket equation, but it's not. It just means to multiply. So you do the bracket equation first [9 + 3 = 12]. The equation now becomes 48÷2x12 = ????. Since multiplication and division have equal weight, you solve from left to right. 48÷2=24. 24x12=288.
My bet is both are correct because the way of this equation is confusing! It could re-write as 48 x 1/2 x (9+3) or 48 x 1/[2(9+3)]. And in computer programming, multiply first, then divide!
Cheers!
Cheers!
EXACTLY... Well said RacerCarl. The answer is clear: 288. This is something you learn in GRADE 8 MATH.The people that voted A don't know their math.

You should listen to the man with the math degree. The answer is 288.
BEDMAS is the correct process (algebra rule), but as explained multiplication and division are in the same step and addition and subtraction are the same step.
The issue people are having is that they are not "finishing" their brackets first and then chosing to try to be chinese/japanese and read right to left???? WTF? We do our equations left to right.
First solve the brackets
48 ÷ 2(9+3) =
No exponents so on to division and multiplication ****LEFT TO RIGHT****
48 ÷ 2 x 12 =
First the left NOW the right
24 x 12 = 288
Don't ask again. This is straight from your elementary textbooks. Not knowing your sequences is probably the largest reason I had to help people with their math equations. You will get the equation wrong every time if you do not keep the correct sequence.
