6/2(2+1)=???

What would be your answer and why? Twitter goes crazy on this 5th grade question, so let me know your thoughts. I will also explain mine later.

my answer is 6, because u divide 6 by 2 which will be 3, and u do 1 + 2 = 3 and then you do 3 + 3 = 6

You failed your math/algebra classes.

There's something wrong with this

Let's say we have 6/2(2+1).
We can replace the (2+1) with x while knowing x=3
Then we get 6/2x=9
Now we solve for x
6=18x
1/3=x

1/3=/=3

But if 6/2x=1
Then we get
6=2x
3=x
That is correct.

But you do 6/2 first, then multiply the result by x, giving you 9 since x=3

2(3) is one value

Let's see

6/2x=9
3/x=9
3=9x
1/3=x

Even if you divide 6 by 2x, it still doesn't add up.

2(3) is one value

But according to the original equation it’s not?

it’s 9 just use BEDMAS

the hell is bedmas

It is, when you plug in a number into a function, the number in front and all exponents (exponents are not relevant here) are 1 value.

The answer should be 9 according to the most modern maths rules. I have a vid from a mathematician explaining it in more detail and why it can be something else.

So you admit you have to do brackets first ?

6/2(2+1)= 6 / (2 x 3) = 6 / 6 = 1​

 

[Azstar]

6/2(2+1)= 6 / (2 x 3) = 6 / 6 = 1​

there's a wiki about why alot people talking about 1 or 9, before it was 1, it just looks like the formula what i typed, 2 have to * 3 to make it to 6 and 6 / 6 = 1. but after someone finds out it will goes to "6 / 2 x 3 = 3 x 3 = 9.
idk how to talk about this

when did I say that they shouldn’t
