What is the answer to this?

[warpus]

That would presumably contain lot of multiple arcs and loops.

It's a dog by the way...

Brings back memories of the math class I got the highest mark in in University.. Combinatorics! I have no idea why I was good at it, really, but I guess I did enjoy it

one..

Now that we've shown how obvious the OP question was (at least, in retrospect), what the hell does this mean?

10 ml/kg/day

Spoiler :

It's a dosing schedule

It looks wrong to me.

 

[Borachio]

10ml per kg of body weight each day.

So if you're 70 kg you would need 700ml every day. Yes? It looks a lot. But depends what it is.

 

[Mise]

Yeah that's what I got from it too. "10 ml per kilogram per day". Ideally it would be written as 10 ml kg^-1 day^-1, because as written it is a little ambiguous.

 

[Leoreth]

Notation is correct as well: ml/kg/day = ml/(kg * day).

 

[Borachio]

(ml/kg)/day would be less ambiguous. Clearly it isn't ml/(kg/day). Well, it could be - but it wouldn't be sensible.

 

[Mise]

Well it depends if kg/day was a typically quoted unit. For example, if I was trying to express how fuel efficiency decreases as car speed increases, I might say that in a 100 km journey, you need 5 litres more fuel for every km/h you drive over 80 km/h. So the number would be 5 l/km/h. Which I would hope would be interpreted as 5 litres per (kilometre per hour). Now, strictly speaking, that's just plain wrong, but, like the aforementioned "convention" that spaces, divide signs, and so on are often not used in the strict BODMAS fashion, people would probably gather what I mean from that statement 9 times out of 10.

I certainly wouldn't write it as 5 l.h/km (5 litre-hours per kilometre). I would most unambiguously write it as 5 l.km^-1.h, though again, that's not very helpful either.

 

[Leoreth]

In casual conversation? Sure. When written, I'd use brackets.

 

[Borachio]

@ Mise

Yes (I think - I'm not awfully good at getting my head round that sort of thing.) But in terms of medication for a person, what would ml/(kg/day) mean in practice?

 

[Mise]

Oh, sure, in this case, ml/kg/day would be typically interpreted as ml.kg^-1.day^-1

@Leoreth: It's not common to put brackets in units. At least I've never seen it done like that. Usually you just "per x" as x^-1. So the unit of Force is kg.m.s^-2, rather than kg.((m/s)/s) or something.

 

[Borachio]

I still don't know what "medication" it is though. A bottle of wine a day, perhaps? Makes me doubt the 10ml figure.

 

[El_Machinae]

I prefer it written as "10 ml/kg per day".

 

[AlpsStranger]

At the risk of looking stupid, I get 7.

6 - ( 1 * 0 ) + ( 2 / 2 ) = 7

 

[Borachio]

Yes, I think most people agree. Now, what was the OP for? There's the mystery.

 

[LucyDuke]

The poll at least shows whose math never to trust.

 

[Ayatollah So]

Spaces are not a mathematical notation!

Ha!

 

[Antilogic]

The poll at least shows whose math never to trust.

Nah, man, you and your dirty commie math rules are all wrong. Ron Paul recognizes everyone's individual right to decide whether the answer to that question is 1 or 7.

 

[bhsup]

Oh my God. Paulculus?!

 

[Antilogic]

Oh my God. Paulculus?!

I would call it paulrithmetic.
