Lets see how many of yall know the right answer to this problem

[L&HH]

Both answers are correct because the equation is written ambiguously.

Should have been:

(6÷2)*(1+2) = 9

or

6÷(2*(1+2)) = 1

Settle down students! The answer is 9.

 

[YoungMasterGold]

Which mathematician says its 1? Standard law of operation (or pemdas) states that division and multiplication are of the same priority, so how could it not be 9?

Yeah, but anything attached to a bracket becomes part of a whole in an operation. Think of it algebraically, the expression should be (in my interpretation): x/y. Where x is 6 and y is 2(1 + 2). Then again, one could argue it all comes down to syntax. . . or something.

lol. this again

 

[Data-Hawk]

yo, the answer is 1.

you're not dumb, you're just uneducated on how to properly to do this question. what you do is follow the rules, and the rules are pemdas, and if you get that you get 1

i'm a math grad student so i hope you can take my word for this.

wow.

6/2(3) automatically makes the answer 1 if you do what's connected to the parentheses first as in Pemdas.

Of course if you apply what's in parentheses to 6/2 instead of merely 2, you get 9.

Wrong. You only do whats inside the parentheses, you don't have to do what is next to the parentheses first.

How are you getting 9 if you use pemdas?

6÷2(1+2)
6÷2(3)
6÷6=1

Because the highlighted step is equivalent to

6/2*3

which gets evaluated from left to right, because neither / or * have precedence over each other. so,

6/2*3 = 3*3 = 9

A number on the outside of a ( , such as 2(3) doesn't have any special priority, it's just a multiplication operation.

x/y

If x = 6 and y = 2(1+2)

6/2(1+2) = 9

The answer is still 9, even if the problem is presented algebraically.

How are you getting 9 if you use pemdas?

6÷2(1+2)
6÷2(3)
6÷6=1

The problem is yall multiplying 2 by 3 first in step two. pemdas states multiplication/division are of the same priority, therefore in step two we work left to right, not right to left.

In fact, everyone that disagrees that its 9 visit this page for 2 or 3 minutes:

Order of Operations - PEMDAS

Otherwise just go left to right. Example:

30 ÷ 5 × 3 = 6 × 3 =
18
(right)

30 ÷ 5 × 3 = 30 ÷ 15 =
2
(wrong)

The red part is what yall doing wrong.

 

[South Paw]

6 / 2(3)

is the exact same thing as

6 / 2 * 3

How would you solve that?
