How do I know? I used a calculator...

Can I get you to run that through a TI-85 and TI-86 please?

i guess for the result being 5 can only be:

6-1x(0+2)/2

6-1x(2/2)

6-(1x1)

6-1 = 5

can't see other way for that silly result lol

Actually, I think 5 came from following the steps EXACTLY in order:

6-(1x0)+2/2 (step 1: multiply)

6-0+(2/2) (step 2: divide)

6-(0+1) (step 3: addition)

6-1 (step 4: subtraction)

5

I, for one, care whether people are able to solve a very basic arithmetic problem. It's representative of the overall level of numeracy.

But yes, it should never be written in such a way.

If you write a book about grammar but do not use any space between words, any punctuation, any paragraph and such would you complain that people don't get it ?

Yes knowing the order of operations is important and yes it's surprising that many people don't even know the basis.

But writing readable equations is as much important imo.

If it wasn't readable nobody would have got the answer!

seriously?

6-1X0+2/2

1X0 = 0

6-0+2/2

2/2 = 1

6-0+1

(6-0) = 6

6+1

(6+1) = 7

how hard is that? Add and subtract does not mean add then subtract, it meants do addition and subtraction in left to right order add or subtract doesn't have a precident, just do them left ot right therefore you get 6 minus 0 first...

the equation rewrites from 6-1x0+2/2 to this (6 - (1 x 0)) + (2 / 2)

additon and subtraction along with multiplication and division are treated at the same precident thats why you MUST do them form left to right...

I am just amazed how so many computer esc people can't grasp at such a simple concept

I think he meant that people who got 5 were following the exact order the operations appear in the BIMDAS acronym rather than the correct order.

6-1x0+2/2

= 6-(1x0) + (2/2)

= 6 - 0 + 1

= 7

Order of operations: 6-(1x0)+(2/2)

Order of operations: 6-0+1

Order of operations: 7

Well that's it. This thread proves that the average neowinian IQ is higher than the avg facebooker IQ.

Uhm...I was merely explaining how someone COULD have come up with 5. It was questioned as to how someone came up with such an answer. I know the what the correct answer is. Next time, try to keep up.

and I was explaining I don't get how people could figure out the logic you explained if you knew the rules where left to right, I wasn't saying you did it wrong, wasn't mocking you or anything, just the people who used that method.. I was explaining the correct way and how could someone even think that's the right way and get five... please don't tell me to keep up, I was just saying The people who got it that way where definatly wrong...sheesh

Hi, new user here :blink: :blink:

I found this site after a quick google for the topic equation, and enjoyed the thread.

Thought I'd like to add some comments. Hopefully the thread hasn't been done to death! :o

A quick bit of background, i'm a 53 yr old electrician from the UK, have an IQ of around 140 so no genius but no dummy either :woot: but able to do arithmetic (just about :D )

I can only speak from a UK perspective, but the arrival of so many different answers to this equation boils down to the age gap IMO. You see, most people of my age bracket were simply taught from infant school onwards to simply read the sums from left to right and complete it as you go along, - hence the answer of 3.5.

A tangent to the arrival of 3.5 is that 5 x 0 was taught to equal 5, the logic being applied was that you had 5 to start off with in the first place, therefore 5 times no more would still equal the original 5 that you started with.

Zero times 5 would of course equal zero. So the layout of the sum, and the equation, gives cause for misinterpretation.

Most of these people left school at 14 or 15 so it might be a moment to pause for thought and consider that this age group have been working and paying taxes to subsidise the better education provided today to the younger generation? So calling them thick or stupid just because they are following the education rules that they were taught is a bit rich. (not saying anyone here has indulged in OTT name calling)

The further teaching was to include brackets to give the semblance of order. So the equation would have been written as:

6 - (0 x 1) + (2/2) = ? if one wanted 7 to be arrived at.

Now I've also had to do some brain numbing mathematics as part of electrical theory as the years have gone by, so i'm well aware of the DMAS order of things, the BO part not being seen as important enough to include as it's too obvious really.

I can tell you that a large amount of students religiously follow the order of DMAS as written, so addition often takes place before subtraction, hence the arrival of 5 as an answer.

Then you get the reliance on modern day simple calculators, which give an answer of 1 if you enter the equation as written.

Therefore all modern simple calculators are manufactured wrongly? :whistle: Hmmm... :rolleyes:

There you go, that's my take on it. 7 would be my answer.

Mark.
