Current Events > 6÷2(1+2)=?

(+) Yeah! (+)

7 is the dumbest answer
---

7 must be your favorite number so I'm voting 9 instead
---

First simplify the parenthesis which gives you 6 / 2 * 3. Because multiplication and division are done at the same time, you solve from left to right. This gives you 9.

I know what people say the answer should be, but the fact that the 2 is right up next to the parenthesis should mean that the entire parenthetical expression 2(1+2) should get solved first. It's not the same as if there were a multiplication sign there: 2 x (1+2).

Somewhere along the way common sense got forgotten. When we write 2(1+2), we mean that those numbers are connected. Otherwise the problem should be written differently:

(6/2) (1+2)

We should write our mathematical expressions like sentences, with numbers "grouped" appropriately to avoid ambiguity. (And yes, ambiguous sentences should be rewritten too.)

You should never use the obelus as a stand in for the solidus.

this. isn't. math.

You're mistaken, but you shouldn't be. The rule is stupid. But technically the rule is that multiplication and division have equal status and you go left to right, so it is solved by adding the 1 and 2 first (because parentheses come first), then dividing 6 by 2, then multiplying by the 3.

But what you wrote SHOULD be the rule. It makes much more sense.

I was always taught multiplication first, in which case the answer is 1

I agree that this SHOULD be the rule, but I don't think it is. And Google says the answer is 9. I think a spreadsheet does, too. (Of course, the division sign has to be replaced with the slash, so maybe that changes the whole thing anyway??)

it actually IS the rule

I'm not used to seeing the inline division symbol, but yeah 6/2 is a single number and not an operation which is why it makes it weird.

Also one would thing the division symbol would imply n*1/x, but it doesn't. It implies 1/n.

why should I? I know the rules. I know how math convention works. if that utility or program gets a different answer than 1 it's because it uses its own syntax convention

Simplified, or rewritten since the division symbol is stupid you would have

(6(1+3))/2
3(1+2)
3(3)
9

this is why people don't use the division symbol.

it doesn't work that way the problem is presented as thus:

x=1 + 2
x = 3
6/2x
6 divided by 2 x's
2 x's is 6
there fore it is 6/6

1.
If there was an x between the parenthesis and the 2 in your equation you would have divided first before multiplying.
As the number was attached to the parenthesis you would then treat it as part of the parenthesis and do it first.
The formula would look like this:

6
___

2(1+2)

If written as more then one line.
---

technically

623(1+2)
=
18/6
=
3

It's kinda dumb. But this is an oversimplification still, because the actual fraction is 18/2/3. Bottom line, never use division symbols, they will fuck your shit up.

(1+2) is not in the denominator by any indicated operator in this equation. I'm not sure why you are putting it there.
---

how do you even get 18, and for that matter 6
---

The parentheses indicate that the denominator isn't simplified. The denominator's quantity is 2*3, aka 6.

So breaking it down
623(1+2)
=
6(1+2)/2/3
=
6(3)/2/3
=
18/2/3
=
9/3
=
3

that's because for calculations using utilities, the division symbol goes
6

2(1+2)

in actual written math that is not the case

oh wait I have it backwards lol

the division symbol is seen as an immediate reaction. that's why programs treat it in order incorrectly

(6(1+2)/2/3) = (6+12)/2/3

transitive property
Edit: you are still assuming that those division symbols imply they multiply directly with the parentheses. They really mean those numbers are (everything else)/2 or /3.

I interpreted it the same way with the 2 right next to the parenthesis the same way with the 2 right next to it

What are you basing this on? Your sixth grade knowledge of order of operations?

It's telling that your argument against my original post was "Order of operations" when the only distinction I made between the two of them was using the obelus() versus the solidus (/). If I didn't understand order of operations, I would have gotten them both "wrong".

Do you know why he stop using around the time you learn order of operations? It's because historically there's a difference between and /, in that using inline is meant to imply that everything to the left is the numerator and everything to the right is the denominator. Unlike the other operations we're used to using, it's not bounded to the symbols immediately adjacent to it.

Now if you want to argue that we should conflate the two, whatever. But don't try to correct people for recognizing the distinction. There's a reason that people want to get rid of altogether. Because it's not presented properly and people think that they're interchangeable.

theres no such thing as 'implicit multiplication', only shorthand so that is in fact done after the division

the division character is used to denote immediate fraction for calculators, but it's not true math format afaik

it's not "implicit multiplication". it's as if the 2 is 2x. and x is 1+2=3. 2x is 6

There it literally no reason to parenthesize the addition like that; let alone, do nothing with the multiplication and division.

Implicit multiplication is just a phrase people use for multiplication by concatenation.

yes there is. variables exist

This is a fairly decent exercise in why the division symbol is shit though. It makes no sense at all, except in the simplest of equations. i.e. 42=2

that's why it's not used. parenthesis is superior to use

So what do you think 6(1+2)2 is
---

18/2 = 9

Also if you convert 2 to its more readable form, *(1/2)
=
6*(1/2)(1+2)
=
(6(1+2)/2)
=
(6*3/2)
=
18/2
=
9
