That divisor symbol is ambiguous. Most people agree however that you treat it exactly like a fractional divisor, so the answer is 2. 288 is also acceptable though because the question is purposely ambiguous. That won't stop autists from arguing about this for days though and getting this thread to 200 replies.

what are we supposed to "solve" for?

>> No.6531940

Solve this faggots.

Let R(n) denote the maximal possible number of different regions obtained by cutting the plane with n straight lines. Give a formula (possibly recursive, but preferably explicit) for R(n) and justify it by an appropriate inductive argument.

>>6531915
When order of operations are otherwise not separated by parentheses, you read it left to right.

So this is precisely what >>6531905 said:

48 * (1/2) * (9+3) = 24*12 = 288

But nobody actually uses the divisor symbol anyway for this exact reason.

Aren't you supposed to answer in the form of a question on this show?

For a prime example of ambiguous notation, look at superscripts. The usual example is <span class="math">\sin^2(x)[/spoiler] versus <span class="math">\sin^{-1}(x)[/spoiler], and you could probably drag contravariant components into this somehow.

Order of operations motherfucker. You do 9+3 first, then times it by 2, then divide.

= 288

You can't assume 2(9 + 3) is the denominator of the operator. When a fraction is written as
<span class="math">\frac{a}{b}[/spoiler]
It is implied as (a)/(b)

Fucking this. The first place i heard about pemdas was on 4chan, who the fuck comes up with this retarded shit?

The way i learned it was 'order of operations' and it was taught in full sentences, not by some retarded fucking acronym.

Its 288 by the way

When I was taking calc 2, the professor used the superscript notation for arcsin (or arccos, etc.) on the first exam, but when I was giving my solution I always wrote out the word. On the rest of the exams he wrote out the words instead of using superscript notation. I like to think that I showed him the light.
