function 2(x) was not previously defined.

It is generally a very bad idea to try and use just numbers to define a function.

Yes. It's inappropriate to use the solidus this way with inline notation. Parentheses should be used or terms should be clearly separated

How is using the slash to indicate divide inappropriate? It's straight forward and not subject to misinterpretation.

Yeah, the inline form of a/bc is often used to imply a/(bc), which is why parentheses should always be used for clarity

I selected 3 but 300 works too.

From Wikipedia
Mixed division and multiplication

In some of the academic literature, multiplication denoted by juxtaposition (also known as implied multiplication) is interpreted as having higher precedence than division, so that 1 2n equals 1 (2n), not (1 2)n.[1] For example, the manuscript submission instructions for the Physical Review journals state that multiplication is of higher precedence than division,[22] and this is also the convention observed in prominent physics textbooks such as the Course of Theoretical Physics by Landau and Lifshitz and the Feynman Lectures on Physics.[d]

This ambiguity is often exploited in internet memes such as "82(2+2)", for which there are two conflicting interpretations: 8[2(2+2)] = 1 and [82](2+2) = 16.[23] The equation "62(1+2)" also gained notoriety in the exact same manner, with the two interpretations resulting in the answers 1 and 9.[

Answer should be 3.

You do the surrounding parentheses multiplication before the division.

Where I'm from, they always taught us that brackets have advantage over fractions.

So 2(7+3) is done first and we end up with 60/20.

"where I'm from" doesn't matter as math is math no matter where you are or how old you are.

It's a troll question for people who think that 2(10) is a parenthesis operation (it's not, it's multiplication, parenthesis are over at this point) and people who think multiplication comes before division because of PEMDAS (M and D are on equal footing and done left to right as written, same as A and S.)

The answer is 300 and your factually wrong if you say otherwise.

When you have a number beside parentheses, the multiplication is implicit, so it's: 60 / 2 * (7 + 3)

First off, get some help. I can only imagine how obnoxious you are IRL if you're so condescending on a random internet board and in such irrelevant topic.

People already told you and quoted sources that it can go either way.
Writing it like it's in the question is also ambigous.

IRL you'd either get a fraction with just 60 on the top and then 2(7+3) on the bottom. (yeah I'm not using proper terminology because English is like my fifth language, what can you do)

Or you'd go 60/2 if it's just that fraction, with 2(7+3) coming after.

Since you're so unmannered, onto the ignore list you go, I've been warned more than enough times because of people like you.

That's some major assumptions you are making. I did not call anyone dumb nor will I, nor did I say or will say how incredibly clear it is.

Now if you really believed what you said, why would you even post? You would simply move on and ignore. Perhaps you are the troll?

Most Math is not made up. But notation is definitely made up. For a real challenge, try doing it using Roman numerals.

300, multiplication is strictly performed left to right and anything outside the parentheses/brackets is never considered part of them.

PEMDAS/BODMAS might be "made up," but it's still universally recognized as the correct way to work your way through calculations to arrive at an answer. If 99% say 300 and 1% say 3, chances are the 1% simply don't know how to use PEMDAS correctly.

I'm not sure what tone you read my post in, but only the first sentence was directed to you, and I don't see where the condescension is. I've just seen this problem (or ones similar) all over the internet and see the same excuse of "in my country it's taught this way" or "back in the day before all this new math it was taught this way" while those are all wrong. The order of operations, conceptually, have been around since the 1600s, but the actual name wasn't until 1912. So unless your REALLY old, math hasn't changed.

But it doesn't matter since I'm apparently blocked. First time I think I've ever been blocked since I rarely post and usually just post information/facts, rarely my own opinion.

If you want my opinion, those people who think if an equation does not have parenthesis that means the order of operations does not apply...thats some crazy logic, and I've seen that way too much recently as these troll math equations go viral.

Or whatever pemdas is is not universally applied and you're only hearing from the dominant group that utilizes it, presumably Americans.

my favorite is the one where if you do the problem wrong, you get n, but if you do it right you get n!. so it looks like you're really excited to give the wrong answer, but you're actually giving the correct one.

Europe developed the order of operations hundreds of years ago and is the same in every other country that has adopted the convention regardless of the mnemonic that each country uses to educate children on how to use it correctly.

So what country are you from that still insists on using its own system since every other country that participates in international scientific research has adopted the European order of operations for the sake of convenience?

With this notation it's not possible to tell if it should be (60/2)*(7+3) or 60/(2*[7+3]), so the answer can be either 3 or 300 depending on how you're feeling at the moment
