[Off-topic] Archer:
The problem here is the difference of opinion on this...

a ÷ b (c)

Some people think it's this...

a ÷ (b * c)

and others think it's this...

(a ÷ b) * c

That specific instance isn't covered by BODMAS, PEDMAS or any other MAS you want to think of, but the fact of the matter is (and yes, it is a mathematical fact that the notation does specifically mean this), it's the first one.

So....

6 ÷ 2 (1 + 2)

Is the same as...

6 ÷ 2 * (1 + 2)

It is not the same as

6 ÷ (2 * (1 + 2))

This is mathematical notation, and is not an opinion.

6 ÷ 2 (1 + 2) = 9

No it's not. The answer is 1. The funny stuff in the curvy things comes first. That's been the rules of Mathematics for hundreds of years - modern stupidity can't change it.

If the question was

then you would do the brackets first, then run left to right. However, having the number attached directly to the bracketed calculation means that you perform that calculation in its entirety before running left to right.

[Off-topic] veeman:
That is false. The 2(2+1) is actually one term and cannot be split up because the 2 has been factored out of the (2+1).
[Off-topic] jaszek:
We're not using factoring here. That 2(2+1) basically mean 2 * (2 + 1)
[Off-topic] jeffreyjicha:
This. And since 2(2+1) = 2*(2+1), there is in fact, two terms there.
[Off-topic] jaszek:
Also someone mentioned programming languages.

C++

#include<iostream>
using namespace std;

int main()
{
int x;
x=6/2*(2+1);
cout << x << endl;

system("pause");
return 0;
}

Java

import java.util.*;
public class XDAnoobs
{	public static void main(String[] args)
{
int x;
x = 6/2*(2+1);
System.out.println(x);
}
}

Go ahead and compile those two. Let me know what the output is.
[Off-topic] Deadly:
Yes, I did... I meant in the sense.. they have operator precedency rules and such.. also, this code you gave above should give 1 as answer.. as both Java & c++ follows brackets as higher priority and then comes either */ and then comes either +-

[Off-topic] veeman:
Nope.

2*3 and 2(3) are both different ways of getting the same answer but are not the same. In one you are simply multiplying a number by a number, but in the other you multiply whatever is in the parentheses by the number directly preceding it.

Y÷X(a+b)

In this case, the x(a+b) would be considered as a single term because of the parentheses. It would be the same as the fraction Y/(x(a+b))
[Off-topic] jaszek:
Dev C++ and jGRASP.

The programs are correct. It ends up as 6/2*3. It goes from left to right, which is what the rules of PEMDAS are. You can do it differently as well

(6/2)*(3/1) = 18/2 = 9

To get 1, you would need to have the reciprocal, but for that the equation would need to end up as 6/2/3.

Thread closed.

Thank you.

Y/X(a+b) is different from Y/(X(a+b)).

And including the letters now makes it more confusing, since with letters (Algebra) you can factor out, so X(a+b) will equal to (aX + bX) which is what we don't want, since we're doing simple math, and not algebra.

[Off-topic] SimonTS:
I don't understand how seemingly intelligent people can continue to claim the answer as 9.

It doesn't matter whether a programming language tells you that, the RULES of maths mean that the answer can only ever be 1.

Forget computers. Forget calculators. Read the RULES and then write it out on paper and you will always get the correct answer.

As I said earlier, there is a difference between ;-

2 x ( 2 + 1 )

and

2 ( 2 + 1 )

Read and learn what the difference is if you're not sure.

To give you a clue ...

2 ( 2 + 1 )

is actually

( 4 + 2 )

What gets me is when people say "The answer is 9 in (insert country / rule-set / programming language here)". The answer is 1 - the answer can ONLY EVER be one if you follow the basic rules of Mathematics. Any other answer means that you are failing to follow the rules correctly.

2 ( 2 + 1 ) is NOT then same as 2 x ( 2 + 1 ). The answer to those two phrases may be the same (6), but the formula itself is different!!

My 10-year old son knows the correct way to solve the problem, so it's obviously not every school in the UK that should be sacking its Maths teacher.

Also the reason why its why is because the order of operations is:

terms inside parentheses or brackets

exponents and roots

multiplication and division //You do these at the same time, they are inerchangable

addition and subtraction

Also the problem with you 1 people is, that you didn't give any proof for your answers.

I don't know why people even start these asinine threads. The problem is horribly written and would never appear that way in any testing, text, or otherwise worthwhile mathematical context.

But hey, I noticed that the same people who argue for the answer being 9, with the problem somehow breaking down to 18/2, are the same people who claimed that .99999 repeating equals 1. Might be arbitrarily close, but it's not the same thing.

Regardless, I doubt I'd be able to figure out related rates, use integrals, and solve differential equations if I didn't understand basic order of operations, but hey, maybe I'm just some kind of savant who can't do the easy stuff. I'm out of this thread, it's not going anywhere.

The problem with that is:

First, you did the (2+1). That is correct

Then, you distributed the 3 to the (3), getting 6. What's wrong with that is that Multiplication and Divison are on the same "level", so you just do whichever comes first, which is 6÷2. You then get 3(3), distribute, and get 9.
