Solve 6-1x0+2/2

80 posts in this topic

It's people who think that because multiplication takes priority in the equation, they can forget about the order for the rest of it :p

(6-1)x(2/2)

yep.

BODMAS in the uk (instead of PEMDAS) but still 7

Both are horrid, there is no such thing as multiplication before division, divison before multiplication or even addition before subtraction.

18/3*2=12

(no it is not 3)

Seeing these one Facebook make me cringe. Most people have no idea what's going on.

7.

used BEDMAS (Brackets, Exponents, Divide, Multiply, Add, Subtract).

I got it wrong until i remembered that mult and division is first.

I was always told that things were done in this order.

So:

6 - 1 x 0 + 2 / 2

6 - (1 x 0) + (2 / 2)

6 - 0 + 1

7

It irks me how people are getting this wrong all over facebook. I recall being taught this at the age of 14 (ish - working out where I was in school based upon where I remember sitting).

People are typing it directly as shown into a calculator, and swearing blind that they are right - because the calculator says so. I have 2 A-Levels in Mathetmatics (pure and statistics) and yet people with less than a GSCE wish to tell me I am wrong. FML!

Who cares if people get it right or wrong.

The matter of the fact is you'll never see such an equation in a book as it would be a terrible book.

Seeing equations wrote like this one anger me more than people who fail to answer it.

I see basic math failed a few people again... PEMDAS people

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.

using BODMAS

B - Brackets first

O - Orders (ie Powers and Square Roots, etc.)

DM - Division and Multiplication (left-to-right)

AS - Addition and Subtraction (left-to-right)

My faith in humanity is restored as most people here are getting it right :D

People that get 1 think that you solve it left to right.

People that get 3.5 think that you solve it left to right AND 5x0 = 5.

I don't really call people thick or anything like that, but if people post calling others thick they should be damn sure they're right in the first place :laugh:

it doesn't matter if you solve it left to right or right to left. Adding integers is most certainly a commutative operation

When I first saw this equation, it really irked me how it was setup. So I got it wrong at first. Then I remembered BODMAS. I maybe an old Jarhead, but my brain does still work without having orders from time to time. ;)

Wouldn't this be considered Elementary-level math?

You claim to be a software engineer; I'm disappointed.

I get 7. I think order is multiplication, division, summation, subtraction. So 1x0 =0; 2/2 = 1; 6-0+1=7. But I could be completely wrong. In science and engineering, only an idiot would write out an equation like that. Scientist and Engineers strive to be specific as possible in their formulations and add parenthesis for clarity even when they aren't needed.

I don't mind people getting it wrong (so long as they're not accountants :p), just hate the cockiness of people saying "You need to go back to school" etc. when they're actually wrong.

I don't care if people get it wrong, it's the attitude of people who insist they're right and everyone else is an idiot even though they did it completely wrong. Someone even said to me "Who the hell are you to say what the order of operations is" :laugh:

it doesn't matter if you solve it left to right or right to left. Adding integers is most certainly a commutative operation

By that I meant in the order that the sums appear. You need to do it in the BODMAS/PEMDAS order otherwise it's wrong.

It's 7. However, BODMAS and PEDMAS are both silly; Division is the inverse of multiplication (special rule for divide by 0, of course) and subtraction is the inverse of addition, so they have the same priority, so you're supposed to do stuff left to right in that case.

For example:

6 % 2 == 6 * (0.5) and

6 - 3 == 6 + -3

So, if you used PEDMAS on 6*2-3+5*2, you'd end up doing addition before subtraction, that is, (6*2)-(3+(5*2)) == -1, which is obviously not the same as 6*2-3+5*2 == (((6*2)-3)+(5*2)) == 19

No PEMDAS is not silly, it is a correct order of operation..

P Parentheses first

E Exponents (ie Powers and Square Roots, etc.)

MD Multiplication and Division (left-to-right)

AS Addition and Subtraction (left-to-right)

if you don't get the right answer following that, you are doing it wrong

No you wouldn't do addition before subtraction, that's only if you take the DMAS part too literally and don't understand the actual rules.

B

O

DM (left-to right)

AS (left-to-right)

is the correct order.

These types of open answer equations always make me rage at the stupidity of some people. Math is beautiful in that there is only one correct answer and if you don't have the correct answer, there is no explaining yourself. The idiots who sit there so assured of themselves with the wrong answer without a care just make me want to punch puppies.

It's true that the order shouldn't be taken literally... but then again anyone who understands the logic really doesnt need PEDMAS or equivalent. Those who use PEDMAS (this thread is good proof) almost always seperate out Division before Multiplication and Addition before Subtraction. In fact I've seen it taught wrong so it's not very suprising so many people don't understand it.Luckily in this instance it works, but it would be interesting to give an equation that requires a thorough understanding of the order of operations.

Well the fact that it has so many variants is a clue that the order of D/M and A/S isn't important :p

BIMDAS

PEMDAS

BODMAS

BIDMAS

PEDMAS

They're just acronyms used to help people remember the order. :p
