Basic Math On Facebook

[max_boost]

The only math I deal with I learned it by grade 4 I believe. All I need to know in my management duties are: how much we make and how much we pay out. So simple. LOL

The only time I apply bedmas is when something like this shows up on beyond or facebook lol As for all the other complex math, fuck it. It took me like 5 attempts to pass math 30.

Correct answer is 9 for the second one lol

I'm just going to preempt the inevitable argument and remind everyone that the confusion from this question comes from some people thinking that there should be another letter in BEDMAS in between E and D for "parentheses adjacent numbers". In this case it would go:

6/2(1+2)
6/2(3)
6/6
1

Just to add to this. The first group of people can be proven wrong when the equation is rewritten as a fraction:

6/2 * 3/1 = 18/2 = 9

The first group would (incorrectly) write the fraction as:

6/(2*3) = 6/6 = 1

The confusion seems to come from what "brackets" means in the order of operations. It just means "do operations inside brackets first" but some people interpret it as "get rid of the brackets" which they do so in this case by doing the 2(3) operation.

This whole thing just proves how useless math is in the real world. Most people get it wrong and the world still continues to chug along just fine.

I got 20, then read 320 and was like - ah wtf! The other 20's make me feel better.

Its 1 for the second one.

6 / 2(1+2)

For whoever thinks its 9 rearrange it properly.

Because there are brackets after the 2 it is

______6______
2(1+2)

which equates to 6 OVER 6 which equals 1.

You can even do it the other way. As calculus has taught us multiply the number outside the brackets by the number inside the bracket)

6 / 2(1+2)
6/ (2+4)
6/6
=1

I can see how it can be interpreted as 9 and if you put that exact equation into a calculator it shows up as 9 (except most scientific calculators). Also multiplication by juxtaposition happens before division. Because there is no "x" in-between 2(1+2) you must multiply that first before doing any other operations. And for you that don;t know juxtaposition just means that you are multiplying by putting things next to each other and not using the "x" sign. So indeed the answer is 1.

See I got 1 the first time I did that one and then made myself go back over it to get 9.. Thinking I jumped ahead with X before I did my /

I'm thinking its 9 now though.

Order of operations puts multiplication and division on equal priority so you do it left to right. By eliminating the brackets by doing multiplication first, you just violated the most sacred acronym evar!!!111!!

+1 I had to rethink my thoughts and its definitely 9..

6/2(1+2)
6/2(3)
3(3)
=9

Not this shit again.
It's ambiguous. Some people were taught implied multiplication takes precedence over normal multiplication and division. Kenny covered it quite well.

Yes there seems to be 26 pages on this shit
Afaik there is no multiplicatIon by juxtaposition rule

a*bc is the same as a*b*c

If u wanna do distribution crap first why not distribute 6/2 into the brackets?

6/2 (1+2)
6/2 + 2(6/2) - here the 2 is implied 2/1 so 2 distributed to the numerator
3 + 12/2
3+6
9

At step 2 u can even do the brackets first which results in the same answer (which then violates the juxtaposition rule....whatever that is...)

The confusion is the lack of brackets
(6/2)(1+2)
What now?
evaluate brackets first? U get (3)(3) the multiply to get 9
If there is some juxtaposition multiplication rule u distribute first I guess
(6/2)+ 2(6/2)
The distribute again
(6/2) + (12/2)
(3)+(6)
9

I think the distribution thing works well if ur actually doing calculus type shit (with numbers and variables that u can't combine any further)
3(1+n) - u can't add 1+n in the brackets so u go to the multiplication part
3+3n
But that's no different from 3*(n+1)

Then u can assume the 6 OVER 2(1+2) thing
But that should be written as 6 / (2(1+2))

While we're at it lets throw Schrödinger's cat shit into it (theres math involved in that shit too, right? Lol)
The answer is both 9 and 1 simultaneously until u write it a certain way (the "observation" part) at which point it becomes 9 or 1 depending on the observation lol

Your first line was right, but then you did multiplication before division in the second line giving you the wrong answer

6/2(1+2)
6/2(3)
3(3)
=9

Left to right division then multiplication.

3(3)
Also written as 3*3
=9

[Wakalimasu]

it's 1

6/2(1+2)
6/2(3)
6/6
1


people get 9 incorrectly assume that 2(3) is 2*3

it's what you do

but 2(3) is a whole number. It's not a multiplication operation.


2(3) = 6

2(3) is not 2 * 3

you can even do the equation like this

6/(2+4)

6/6

1

Nah, it's 9... tell me, what is:

2y

or

2sin(x)

?

And the initial question is 20.

But its not a whole number.

First is 20. Second is 9.
