@mario-fan (brackets) in mathematics means multiplication.

[jamjam]

@nastasio 1 and 9 are both possible. 9 is the solution with the modern method, 1 is the solution with the older one

@katie_15 we follow PEMDAS
(solve whats in the parenthesis, then exponents, multiply, divide, add, subtract)

@khai Exactly!

[jamjam]

@sologeek so my initial thought was right i guess

[Jacquees]

i think 1 is the correct answer and 9 is not correct.
because 6÷2(1+2)= 6÷(2+4) or 6÷2(3)= 6÷(6)= 1
And 6÷2(1+2)= 6÷2(3)= 6*1/2(3)= 6/2(3)= 6/6= 1
But at 6÷2(1+2)= 6÷2(3) i don't think one can make 6/2 because you have to finish the product first like this you could say 6÷[2(3)] thats why i think you have to calculate 2(3) first. So its 6÷2(3)= 6÷[2(3)]= 6÷(6)= 1

Further, from a logical perspective, 6 divided by something which is bigger than 1, in this case 2(1+2), can not be 9 ! the only way 9 can be the answer, is 6÷0,75=9,
but we all know that 2(1+2)≠ 0,75 but 2(1+2)=6 ! so we have to calculate 6÷6=1 and thus 9 can not be the correct answer.

@jamjam i posted a new answer, in which i made sure that 9 can not be the correct

[jamjam]

@nastasio looks right to me. The answer has to be 1 then.

[Stranger101]

9. Following PEMDAS.

[cutie cat]

@ragnar-lothbrok 9 i guess, according to bodmas

[one]

Naah naah na bruh never math I don't like..

[Lucifer]

its 1. like @one

@lucifer_ haha bro right
