Use BEDMAS

 

Brackets: (1+2)  = 3

Exponents

Division: 6/2 = 3

Multiplication: 3x3 = 9

 

Use BEMDAS

Brackets: (1+2)  = 3

Exponents

Multiplication: 2x3 = 6

Division: 6/6 = 1

 

Using calculator 

9

It's 9

google does order of equations wrong, I hate math but even I remember pemdas, 2+1=3 so it becomes 6 divided by 2 times 3, which becomes 6 divided by 6 which becomes 1. Course if we want to go by how calculators do it today instead of the historical version it's 9 but I really think that's just lazy order of equations. Idk maybe my math teachers were just old.

This is incorrect

PEMDAS is

Parenthesis

Exponents

Multiplication/Division (left to right)

Addition/Subtraction (left to right)

So P is first in PEMDAS

1+2 is 3

Now its MD of PEMDAS

Going left to right, the division is first

So we get 3(3)

Which is 9

You're using PEDMAS for that, PEMDAS is multiplication first. At some point it switched and I can't quite remember when. You don't go left to right you solve all for each letter first, that's why at some point PEMDAS became PEDMAS.

Answer is 1

This is dumb

 

okay, 1 pemdas is pemdas, you go left to right it doesnt mean you do multiplication first. 2 

 

6/2(1+2)

6/2(3)

3(3)

9

you go from left to right no matter what it says, so even if it is multiply and then divide in pemdas you go from left to right

This is how order of operations works, pemdas and pedmas are the same thing, just different specifications based on which comes first left to right

The reason they both exist is because when you lay out the equation on paper which one is left and which is right, the left to right rule doesn't work when you get to algebra or solving both sides of an equation,

which is why instead of this left to right thing you just switch from PEMDAS TO PEDMAS, often a question will actually mention which of the two to use because the left to right thing leads to errors, it did for me when I tried doing it during engineering math in first year, that's why I really don't like mentioning it.

A mathematician would just tell you to stop being so vague with your parentheses

This basically, it's just poorly written and leaves it too open to interpretation as to how the question is laid out, if the person who made it wanted a proper answer they would've listed what order to use.

Think of the Parentheses as 2 unseen hands of sorts. Each side cross out to the other one by an opposite sign, and it makes a Multiplication Symbol. Of course, you can't see the Multiplication Symbol. It looks like "6 / 2 (3)", but it's actually "6 / 2 X (3)", which simplifies to "1".

Specifically, I learned that you were supposed to do everything in the specific Order Of Operations given. May be wrong to current standards, but that's how I was taught.

My Meme Answer is 6.

Wait, I thought for PEMDAS once you got past the parentheses and exponents, you automatically went to multiplying/dividing from left to right, doing whichever came first. So 6 / 2 (1+2) goes to 6 / 2 (3)

Then 3(3) = 9
