The answer is 1, the 2 is part of the p
Really ? How about 6÷2(1+2) 3(1+2) 3(3) 3 x 3 9.
@@abednego45 no It’s 6 ---- 2(1+2) The 2 is with the parentheses
It's not a real problem is it? If you were doing a calculation and this occurred you would know what it meant. It's only an issue if someone else wrote the problem. The 'rules' of BODMAS are purely arbitary.
Really ? You think so .? What is your conclusions is the answer 1 or 9 ?
@@abednego45 Read my comment again, try to understand it and then realise that the exercise is pointless. The only time you would get a question llike this is in an exam, not in a real mathematics calculation.
Ok ooooooo
The answer is definitely 1. Parenthesis remains intact after performing whatever is inside it, i.e. = 6÷2(3) = 6÷6 as parenthesis comes first. You get 9 because ( ) was downgraded to x, a no-no according to PEMDAS. Algebraically, 4a÷2a = 2, not 2a^2.
Really ? Consider 6 ÷2(1+2) = 3(1+2) 3(3) 3 x 3 9. Check it
nope everything inside the brackets are evaluated anything outside the bracket is just a multiply so its 9
Really ?
Written so that a programming language can solve it: 6/2*(1+2). Both Python and Perl agree that the solution is 9, which I could check quickly in the shell. The expression in parens is solved first (-> 6/2*3), and then we solve this from left to right. I wonder if it might be different in languages like Arabic or Hebrew, where it's read from right to left? 🤷♂
Really ! Now consider 6÷ 2(1+2) 6÷ 2(3) 6÷6 1 How about that ?
@@abednego45 You first solved 2*3, so started on the right. But in the western world we solve expressions from left to right, so 6÷2 comes first, no matter how many spaces you put after the ÷ to irritate people. The whole thing should be written (6:2)x(1+2) in the first place to make the intention even clearer.
Wow nice
You inserted a * which isn't there, changing the order of operation. Algebraically, 2a ÷ 2a =1 always. Your erroneous approach will give a^2.
@@leongchunnam1569 There are no variables in the given "problem". Replace your 'a' with a number, e.g. 3, and you get 2*3÷2*3, which is 9. The function you assume here is different and would be written like this: 2a ---- 2a Ask any mathematician or google for the correct answer - I'm out of here.
This is a deliberate failure of the question to cause so much confusion in the possible solutions.
What is your answer ?
Distributive Property of Multiplication over Addition. The answer is 1.
Really ?
Consider 6÷2(1+2) 3(1+2) 3(3) 9 🤷🤷🤷
It depends if your country teaches multiplication then division left to right, or multiplication and division left to right.
Mathematics rule is universal
@@abednego45 Mathematical properties are universal, but notation and conventions are not. This particular example is a common debate because it is a slight difference between two major english speaking countries, but many of other countries represent things in different ways. Some represent place value right to left instead of left to right, some use different bases (although that is much less common now), and don't get me started on the difference between commas placements and decimals notations.
Ok nice opinion 👏
6 : 2(1+2)= 6 : 2(3))= 6 : 6 = 1
Wrong
The answer is clear; it is 9. 6/2*3, left to right.
Some persons says that the answers can be 1 and 9 at the same time , How about that ??
Consider 6÷ 2(1+2) 6÷ 2(3) 6÷6 1 Check it
@@abednego45 There has to be one and only one convention, and that is: (1) resolve parethetical expressions left-to-right using hierarchical rules, and then perform operations according to the hierarchical rules: exponentiation, mutiplication and division, and the addition and subtraction.
@@abednego45 That violates the order of operations. Multiplication and division are on the same level, so you go left to right.

What is the answer 😂😂😂
When I was in college and university, long time ago, we didn't know PEMDAS, so the answer to this problem was 1 because everything on the right of the "devide" sign was supposed to be denominator. But today, using PEMDAS, the answer is 9
Really?
pemdas forgets to mention the left-to-right rule when operations have equal precedence, then this is superseded by juxtaposition which is between exp/log and mul/div, it's slightly stronger than mul/div and left-to-right. this was agreed so that there is shorthand way to express intent concisely without littering parenthesis, pemdas is the worst thing that has happened to mathematics teaching because it trivializes and forgets to explain every rule.. if you just follow it confusion erupts
@n00blamer exactly
@@abednego45 It's kind of ridiculous now as you can even ask some PhD maths guy and he says "oh well it was changed at somewhere along the way" so it comes down to who you ask... ridiculous.. luckily I am already old and don't have to see this crap more than 50 years more, tops.. =D

Sorry but this is incorrect, you are fall in a common error. Correct solution: 6 ÷ 2(1 + 2) = = 6 ÷ 2 • 3 = = 3 • 3 = 9 This becouse after sum: 1 + 2 we must do all operation from leaft to right; so first 6 ÷ 2 = 3, and after 3 • 3 = 9. Another wey to resolve this equation without need the previus rule is: 6 ÷ 2 • 3 = = 6 / 2 • 3 = = 18 / 3 = 9 In this pther method (PS I used the '/' how fraction simbol) we can du a fraction with 6 and 2, becouse without braket on the 2 • 3 the only number at the denominato is the 2 (Difference: our form => 6 ÷ 2 • 3 = 6 / 2 • 3 other form => 6 ÷ (2 • 3) = 6 / (2 • 3) = 6 / 6 = 1); at this point we can both devide 6 for 2 and moltiply the result (3) for 3 (how first method), or moltiply 6 for 3, and divide de result (18) for 2. Ps sorry for my bad English, but I'm italian, and I don't know it very well.
Nice observations
Addition can be done left to right Or from right to left It just that we are used to carrying out operations from left to right
@@abednego45 Correct, but the error is not in the addition, but in the division and multiplication. Let me explain better; in a succession of additions / multiplications you can do everything from the right or from the left indifferently Example: 4 + 7 + 5 = 11 + 5 = 16 4 + 7 + 5 = 4 + 12 = 16 4 • 7 • 5 = 28 • 5 = 140 4 • 7 • 5 = 4 • 35 = 140 But if you do this with subtractions and divisions, you find an error Example: 4 - 7 - 5 = (-3) - 5 = -8 4 - 7 - 5 = 4 - 2 = 2 (ERROR) 4 ÷ 7 ÷ 5 ≈ 0.571 ÷ 5 ≈ 0.114 4 ÷ 7 ÷ 5 = 4 ÷ 1.4 ≈ 2.857 (ERROR) This can make you understand that if you mix multiplication and division as in the expression you solved, you cannot solve the everything from right to left except if you use the fraction notation instead of the classic division symbol, so in that case, taking up the expression that you got wrong, we find ourselves in the second resolution method that I explained in the other comment. P.S. Sorry if I'm only replying now but youtube sent me a notification of your reply today.
Thanks for watching 🎉🎉🎉
Really 🎉🎉🎉
It's important to know and utilize the Distributive Property of Multiplication because later on in higher order math not all operands are known variables....
Nice , so what is your position on the answers : 9 or 1
NEITHER of your solutions is correct. Your arithmetic is wrong. The DIVISION operator/symbol is =/EQUAL to being a FRACTION symbol. THUS can be REWRITTEN as 6 OVER 2(1+2). 6 as Numerator and 2(1+2) as Denominator. At which point you should SIMPLIFY the Denominator to then calculate the rest of the problem. You go wrong when you say 1+2=3. Arithmetically correct BUT in context of 2(1+2) INCORRECT. You DISTRIBUTE the 2 outside the parenthesis to the 1+2 through Multiplication. Also known as the Distributive Property of Multiplication. Thereby resulting in 2(1+2) = 2+4 = 6. Which now leads to 6/6. You can now solve. Equals 1.
What is the correct a answer ?
@@abednego45 the teachers i learned math from... looking ONLY at the final calculated values IS WRONG. so to sit there and badger people with 'is it 9 or 1...' IS WRONG IN OF ITSELF. showing the APPLIED ARITHMETIC is PART OF THE ANSWER. Not showing the Distributive Property of Multiplication, which SUPERSEEDS any form of BODMAS/PEMDAS (because it is a FUNDAMENTAL OF THE OPERATOR ITSELF) IS WRONG.
PEMDAS
What is your answer 9 OR 1 ? 🤷
@@michaelbates8623 It really doesn't matter which mnemonic device that you use as long as you understand the concept. People make the mistake of thinking that the expression evaluation MUST follow in the order that the letters appear in the mnemonic device. That is merely a "crutch".
You think so ?
@@abednego45 If you are addressing me, why would I say otherwise? 🤔😉😀😃
Solve what's inside parens, then multiplication and division from left to right. =9 Unless you can make the case that multiplication must be solved first.
Really ? That question 1 and 9 seems to be the solution
I'm not going to watch the whole video, because it is just like the ones that pop up several times a day, all essentially the same. The victim is someone who doesn't know the correct sequence of operations. But almost all those videos fail to suggest that the person who WROTE the problem is at fault for the confusion. In the above "viral" math problem, if the problem's author had written (6÷2)(1+1) then everyone would get the same answer. If the author had written 6÷(2(1+1)), everyone would get the correct answer. The point is that the person giving the problem should take responsibility for making it clear, usually by using enough parentheses to eliminate ambiguity. In so many of these videos, the responsibility is passed to the reader, who is expected to memorize a conventional rule and follow it.
What is your final answer ? 9 or 1 ?
I don't see any problem with that task.
Ok nice
Multiplication and division are inverse operations. So convert the expression to all multiplication. 6÷2(1+2) 6*0.5(1+2) 6*0.5(3) 3(3)=9 Multiplication is commutative. So you can multiply in any order and achieve the same result. 6÷2(1+2) 6*0.5(1+2) 6*0.5(3) 6*1.5=9
9 is the correct answer. It isn't that hard of a problem to solve. People saying 1 are wrongly using the distribution property. It is 2 x whatever is inside the brackets.
Like seriously 🤷🤷
where are you from?
What is your answer 9 or 1 ?
@@abednego45 Both could be depending on the country. Some countries said 1, while most westerners said 9.
@night00glider LoL
Prabuji i am shocked at your comment. There are no tricks besides your trick. And i am so embarrassed that you are an Indian yet you cant give the correct answer. I always say you can beat an egg but you cant beat an Indian. But will make an exception in your case.
6÷2(1+2) = 6÷2×3=9. I used division first. If i used multiplication first the it would be 6×3=18÷3=9 6÷2×3=6×1/2×3=9. Now you are saying 6÷(2×3)=6÷6=1. I will pay for your head to be examinef Now -2+3= -(2-3) =1. Thats distributive property. Similarly ÷2×3 = ÷(2÷3). Pay careful attention to my use of distribution. =÷(2/3). Now we have 6÷2/3=6×1/2×3=9. Where can you fault me The video maker has the temerity of saying both the answers are correct. Bulldust. Maths is a precise language. You can stand on your head and whistle through your backside the only answer is 9. You van challenge me any time. I am just any Tom, Dick and Harry. My Whatsapp number is 0837781459. I am a south African indian. You guys dont know maths. That why it goes viral. maths is simple but people like you make it complicated. Thanks
