You are not applying bodmas correctly. You don't have to add bracket except there is already a bracket in the equation.

You keep talking about "Mathe", pure maths, dialects and what not. If you could only bring some evidence for your claims. But please don't say that BODMAS is being used incorrectly. Here's what Wikipedia says about the order of operations:

The order of operations used throughout mathematics, science, technology and many computer programming languages is expressed here:[2]

- exponents and roots
- multiplication and division
- addition and subtraction

(Source: https://en.m.wikipedia.org/wiki/Order_of_operations )

So it's Addition AND Subtraction. NOT addition then Subtraction. Both have Equal order of precedence. Neither precedes the other. Please.

Simply put: if I have 6 oranges in a bag, take away none (zero) and then add 1 orange, how many would there be in the bag eventually?! 5?! Or 7?

Like many have said, this is primary school maths and it's quite sad a simple question like this has become a debate. It's a challenge for us to step up our game and improve ourselves intellectually. There are many resources in the Web for learning - instead of wasting data money and time on gossip, movies and what not. And then we complain we can't get jobs!! We really are the bane of our own problems.

If the equation were such that it compressed to be 6-1+1 ?
I could say that i have (6-1)+1 or 6-(1+1).
The first would be the same as saying i have six oranges and then i subtract one to have five and then i add one to bring me back to six.

The other phrasing or interpretation could go as having six oranges and then subtracting a number of them equal to the value of one plus one which is equal to two. That would leave me with 4 oranges.

In the case where you had subtraction of zero oranges, it was more straight forward to your point of being 7 as the answer.

But when you consider in a dialectic way and open minded consideration, you will see the same straight forward interpretation is not the same in all cases. I respect your respect for syntax, but there is the matter of semantics that makes variable interpretations defy a standard one rule fits all... Bodmas has been about arbitrating what is truly an amorphous thing ( math ).

And Yes there is a reason why subtraction is listed after addition in the order of Bodmas and it makes a differnce
Look at 6-0+1. When i have followed bodmas all the way down to the final step of addition and subtraction, there is a final rule to consider to simplify the confusion that can happen such as the parradox i explained above with 6-1+1..
The rule that helps arbitrate the two different ways of approaching 6-1+1, also simplifies the approach to the answer of 7 in the case of 6-0+1.
That rule is: when you have a final line up of numbers to be added and subtracted for a final total, Move all the subtraction properties and their values to the rear of the lineup and let the additive properties and their values stay in the front of the line up.
Such as rephrasing 6-0+1 as 6+1-0.. That will settle the matter as 7 and explain why itwas a better idea to put subtraction as the last in the order of process called BODMAS

In the case of 6-1+1, it is more abitrary, could go either way depending on interpretation and so the rule used for Bodmas will determine if we take 6 oranges and subtract a value equal to one and one oranges to have four remain, or if we take six oranges and subtract one orange and then add one back to remain with 6.
Bodmas will tell us to move the subtraction to the very last place and then we have 6+1-1=6. Rephrasing to have the suntractin be last in the lineup

This is my explanation about dialectics revealing the nature of pure math and why we are taught math with rules and formulas that arbitrate math's tendency to go many different directions to find varied results.
The truth of math is dialectic and as malleable as languages and their many dialects and interpretations. Only imperfect or arbitrary rules, formulas and standards help arbitrate math so that we dont all run around with a thousand differnet languages and confusion, or should i say a thousand different answers to the same equations.

I really love open mindedness in the face of pure math which invloves simple arithmetic equations as well as quantum theory conundrums.
Open minds will denifinitley guide me out of the small box of a stagnant job labouring away at someone else's individual profit making, rules and ways of seeing the world.
The truth is that even schools in USA are changing the way math is done in primary school ,and the old university graduates are furious because they dont find it easy to do and they feel cheated.. But thats what happens when people think that life is one concrete standard, method, formula or interpretation.
Even wikipedia will have to regulary update itself over time as more is revealed in the world and all subjects and matters at hand evolve in human understanding.
We will never reach the evolution by staying stuck in a box just to qualify for a job or justify a rigid way of thinking and living.. Open the mind and discover beyond what has been conditioned within by those who came before. Thats how life will become better and understanding expand.

I am trying myself, not easy to make sense of so much confusion.

Your explanation is on point and I like it, but you know what? Strictly using the bodmas also gives you the same answer of 7. The trick there is to know how to use the bracket


You have ; 6-0+1 right? Bodmas says addition before subtraction so you should convert it thus:
6-(0-1)= 6-(-1)= 7.

This can also work.with the 6-1+1 that you termed arbitrary.
Its 6-(1-1)= 6-(0)= 7.


The trick is to know how to use the bracket when needed.
QED.

semitunde:


When it comes to maths, be very sure of yourself before crossing others OK?

Modified: you should have just corrected the answer, not flay the calculation, which is correct.

19naia:




6-1x0+2/2.. 6-(1x0)+(2/2).. 6-0+1=

See above just that. Adding brackets are allowed and can work out functionally.
The confusion is not in the added brackets, it is in the final step where subtracting zero and adding one creates a problem.

if 6-0+1 were solved like 6-(0+1).. It would be 6-1 and yield 5

The same equation can be rearranged before solving, so that
6-0+1 is rearranged to be 6+1-0. Therfore (6+1)-0 and the yeild is 7. Also as 6+(1-0)=6+1=7

SEE BRACKETS ADDED AND EVEN SO IT YEILDS YOUR CHOSEN ANSWER OF 7 as well as the answer of 5.
The issue is not the the brackets. It is in the way if factoring in the zero in terms of - or + properties.


What if the equation compressed down to 6-1+0 ?
we could do 6-(1+0) and get 6-1=5..
Also we could do (6-1)+0 and get 5+0=5.
In this case the answer is consistently the same. by my methods and no confusion even after adding brackets.

So you see, the brackets are allowed to be added so long as they are the first to be solved before then adding or subtractiing or any operation in Bodmas..
The confusion has nothing to do with added brackets, it has to do with the zero being factored in terms of a negative property. The Zero being subtracted is the issue creating confusion, not the brackets or the method. Also Bodmas is imperfect when you see the addition and subtraction phase of the order bring out inconsistencies in one form of the equation versus the other. So it requires extra scrutiny and rules to decide which is the better answer.
Trust me when i say i agree with the answer 5 and the answer 7.
I just modelled enough equations above to show how the process i originally used ,can both yield the correct answer and a confusing answer depending on the make up of the equation.
In this case, i would add a rule to Bodmas to settle the confusion, saying that after all operations before the final addition and subtraction, any value in the lineup to be subtracted must be moved to the very last place in the equation line up. This rule also supports why Subtraction is listed last in the Order of Bodmas even though addition and subtraction are often said to be interchangeable.
That would solve the issue and yeild 7 in the OP's equation, and i solved for a resulting 7 using the same method and added brackets as i did when yeilding 5. The big difference was rearranging the equation so that the negative property values were moved to the very end of the line up of numbers to be added and subtracted.


But if the equation compresssed down to 6-1+1, would i go with 6-(1+1)=6-2 =4 ?
Or would i go with (6-1)+1=5+1=6 ?

19naia:


If the equation were such that it compressed to be 6-1+1 ?
I could say that i have (6-1)+1 or 6-(1+1).

hollowpot15684:


Believe me using bodmas ordinarily will give u both 5 and 7 as the ansa.
Proving in this case will solve the qst.

SadiqDO:


I once taught JS2 students factorization and at least a few of then would understand very well that 6-1+1 is not equal to 6-(1+1). Rather, 6-1+1 = 6-(1-1) [by factorization rules, if you want to bring out the minus sign].

It's either you're making a big mistake or all this talk from you is just one big joke!
