48÷2(9+3) = ???

[Happy Monkey]

Of course, on page 2 of that article, it says the jury is still out on whether the shorthand of skipping a multiplication symbol changes its place in the order of operations.

This is pretty much all Flint's fault.

He's crazy.

I don't see what the big deal is. Just do it the regular way.

you mean, like, in the butt?

I would say 288 myself, but in all honesty, I don't give a shit what the answer is.

Why not just write it as (48/2)(9+3) in the first place?

Because then we wouldn't have to get into a fucking argument about the conventions of mathematical notation.

48÷2(9+3) = ? is a math problem that, depending on the order of operations used, leads to two different answers: 2 and 288. It can be a hot topic for debate, and is sometimes used to troll other users because of the argument that can result afterward.

Standard Order of Operations
If one strictly uses the standard order of operations to solve mathematical expressions, the answer to the problem would be 288, which is also the same solution provided by WolframAlpha and Google.
By convention, the order of precedence in a mathematical expression is as follows:
Terms inside of Brackets or Parentheses.
Exponents and Roots.
Multiplication and Division.
Addition and Subtraction.
If there are two or more operations with equal precedence (such as 10÷2÷5 or 7÷2*9), those operations should be done from left to right.
Therefore, the problem “48÷2(9+3) =” would be solved like this:
48 ÷ 2 * (9+3)=
48 ÷ 2 * (12)=
48 ÷ 2 * 12=
24 * 12=
288

However, the answer 2 could be justified by the principle of implied multiplication. For example, consider the problem "2/5x."
If one strictly follows the standard order of operations, the correct interpretation would be “(2/5)*(x).”
But many calculators and textbooks state that a higher value of precedence should be placed on implied multiplication than on explicit multiplication:
Because “5x” is implied to be "5*x," it gets higher priority than "2/5." In this case, "2/5x" would be interpreted as "(2)/(5*x)."
Returning to the original problem, if one utilizes the principles of implied multiplication, then “2(9+3)” gets higher precedence than the explicit “48/2,” and would be solved like this:
48 ÷ 2(9+3)=
48 ÷ 2(12)=
48 ÷ 24=
2
However, there is a lack of consensus on the value of implied multiplication.

Now, see, I would hold that Mathematics can't allow for anything "implied". It's either multiplication, or it isn't.

[Pico and ME]

Thats a great response Ibram! I feel vindicated...thank you,

I agree with this, and also think the answer is 288. But there's at least some debate even among mathematicians about the legitimacy of implied multiplication.
