9 because we have to solve it by Bodmas method

[donatehyles]

I love how many hypocrites all over the social media argued that the education system failed you if your answer is 9, ironically which was really the correct answer.

Why guys dont u doubt, the fault is with the writing the procedure when we have more brackets to use with

[VibeGuy]

6/2(1+2)=9
Because 6 halves is the coefficient of the parenthetical.

6÷2(1+2)=1 Because 6 divided by the quantity of 2(1+2), which is 6, and 6÷6=1

The ambiguity only arises when the slash is used when actually the ÷ operator should be used. Treat the slash as juxtapositional/implicit division and the ambiguity goes away.
4/2(1+3)=8 because 4/2 is the coefficient of the parenthetical. Similar to the formula for spherical volumes 4/3πr³.
4÷2(1+3)=0.5 because it is 4 divided by the quantity of 2(1+3). Similar to the problem of calculations for revolutions of a wheel.
120"÷2π(11"+1")=1.59 revolutions. 120"÷π(22"+2")=1.59 also. Regardless of which formula for circumference is used.
In that way, both implicit operations have the same priority and the same left to right rule applies between the two.

Wtf can you divide the denominator of 6/2 with 3 instead of the numerator 🤨

[osamamanan]

The bracket takes precedence always. The calculators are programmed differently. The scientific calculator that can use fractions will compute it as 1 as it will solve the fraction first. I.e. 6 divided by result of 2(2+1). Some calculators which cannot give answer in form of fraction i.e. give decimal answer will compute it as 6÷2 and multiply by 3. Which will give 9. As a human being following a rule book I will give 1 as the answer as I will assume that the part pf bracket multiply by 3 belongs to the denominator.

You take bodmas/bedmas/pedmas, it says first brackets/parentheses, they did it, how can they multiply next, in bodmas/pedmas/bedmas, division comes before multiplication, it's not this 6÷{2(1+2)}, it is presented as 6÷2(1+2), so after getting 3 in from 2+1, you need to do 6÷2 to get 3, then 6÷2(1+2) = 6÷2×3 = 3×3 = 9, the bedmas/pedmas/bodmas says the answer to be 9

[vinakshiparamjit]

9 is the correct answer according to Bodmas and also left to right.

[HansiAlahakoon]

The bracket is first because it is how in pedmas and in bodmas brackets first parenthesis are also called brackets

[HowsTheJosh]

I m iit Guwahati and the answer is 1. 2 is with bracket so finish that first

[GanonTEK]

It's simply ambiguous notation. A trick.
Academically, multiplication by juxtaposition implies grouping but the programming/literal interpretation does not.

Wolfram Alpha's Solidus article mentions the a/bc ambiguity and modern international standards like ISO-80000-1 mention about division on one line with multiplication or division directly after and that brackets are required to remove ambiguity.

Even over in America where the programming interpretation is more popular, the American Mathematical Society stated it was ambiguous notation too.

Multiple professors and mathematicians have said so also like:

Prof. Steven Strogatz, Dr. Trevor Bazett, Dr. Jared Antrobus, Prof. Keith Devlin, Prof. Anita O'Mellan (an award winning mathematics professor no less), Prof. Jordan Ellenberg, David Darling, Matt Parker, David Linkletter, Eddie Woo etc.

Even scientific calculators don't agree on one interpretation or the other.

Calculator manufacturers like CASIO have said they took expertise from the educational community in choosing how to implement multiplication by juxtaposition and mostly use the academic interpretation. Just like Sharp does. TI who said implicit multiplication has higher priority to allow users to enter expressions in the same manner as they would be written (TI knowledge base 11773) so also used the academic interpretation. TI later changed to the programming interpretation but when I asked them were unable to find the reason why.

A recent example from another commenter:
Intermediate Algebra, 4th edition (Roland Larson and Robert Hostetler) c. 2005 that while giving the order of operations, includes a sidebar study tip saying the order of operations applies when multiplication is indicated by × or • When the multiplication is implied by parenthesis it has a higher priority than the Left-to-Right rule. It then gives the example
8 ÷ 4(2) = 8 ÷ 8 = 1
but 8 ÷ 4 • 2 = 2 • 2 = 4

[dreamkorea]

Answer exactly 💯 9 .
6/2(1+2)=9✓

(6÷2)(1+2)=9✓
If the problem is
6÷{2(1+2)} then ans will be 1.
6÷{2(1+2)}=1✓
Look here guys

[dgkcpa]

6/2(1+2) = 1 6/2x(1+2)=9
Two different problems, two different solutions.

[student]

wtf, Have you been drinking?
(1+2) is in numerator, not in denominator, so answer is 9

[roghainashakir]

Acc to bodmas ruke its 9... And if followed pedmas, so 1.... Oh my dear goodness! Finally brotherhood between maths collapsed... Now we will sit and watch it fading away 😂🎉

[aurkomolla]

If it is
6/2(1+2) then ans is 1
But if
6/2×(1+2) then It's 9

[crazytuber]

Both are correct ...the problem is in the question itself

[BikeshSunar-yutg]

According to the bodmas 9 is correct answer

[sivananthanrangatharan]

By the law of Bodmas 9 is the correct answer
