Basic Math On Facebook

[sexualbanana]

A radio station in Saskatchewan has posted a couple of these images over the last few days.

It's been awhile since I've done a basic math equation like this, but I'm pretty sure the answer is
320

However, the number of answers in the comments that don't match mine are enough to make me doubt myself.

[zieg]

BEDMAS.. My half assed guess is 4.


edit: mental math fail, missed a 16, but I agree with the responses that say 20.

[colinxx235]

320...?

Answer is 20

[danno]

i get 20 as well.

[ryanallan]

lol, I hope the "3" was a typo.

[sexualbanana]

You guys must be literally applying BEDMAS in that order. I'm pretty sure the real of operations is: BE(DMAS).

1) Brackets
2) Exponents
3) Division/Mulitiplication/Addition/Subtraction; once the brackets and exponents are cleared out, you do the equation from left to right. Not division, then multiplication....

[dj_rice]

(4X4) + (4x4) + 4 - (4x4)

16 + 16 + 4 - 16 = 20


I think thats right.

[D'z Nutz]

So you mean we must be literally doing it correct? :rofl:


Guess that 3 wasn't a typo

[JordanAndrew]

I get 20 as well. :dunno:

[ga16i]

Answer should be 20. That's exactly how BEDMAS should work.
Try typing that exact line into a calculator and you should get 20 as well.

[sexualbanana]

According to how I did it...

4 x 4 + 4 x 4 + 4 -4 x 4

= (4 x 4) + 4 x 4 + 4 -4 x 4 = 16 + 4 x 4 + 4 -4 x 4
= (16 + 4) x 4 + 4 - 4 x 4 = 20 x 4 + 4 - 4 x 4
= (20 x 4) + 4 - 4 x 4 = 80 + 4 - 4 x 4
= (80 + 4) - 4 x 4
= (84 - 4) x 4 = 80 x 4
= (80 x 4)
= 320


No?

= (80 + 4) - 4 x 4

= (80 x 4)
= 320


No?

You work in finance or accounting, right?

[sexualbanana]

I had to wikipedia. Turns out I'm wrong. B, E, DM, then AS.

I thought you just worked it out left to right since there were no brackets. I guess this explains why I was so bad at math in school. :banghead:

NOPE this should be the way it's done, which DJ_rice has already posted.

Order of operations is, using your acronym:

B/E/DM/AS

not

B/E/DMAS

You can always verify the answers to these weird FB math problems switching the Windows calculator to scientific mode and then just pasting in the equation.

Standard mode ignores order of operations and you get 320. Scientific mode spits out 20.

I am glad I got 20.

Is the answer to the second question 1? Lol

[GoChris]

Ya 20. It's sad to see so many people on facebook argue about the wrong answer.

[Twin_Cam_Turbo]

Agree with 20.

[Tomaz]

I came up with 20.

The second question, I got 1.

I also has the lowest math score in MRU history according to my prof! lol

It's 9
We read left to right

:thumbsup: 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

The other group of people believe that a multiplication sign is assumed between the parentheses and adjacent numbers:

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

Wolfram Alpha and Windows Calculator both agree with the 2nd group. In fact, WC won't even allow you to input the equation as written. It forces an operator in between '2' and '('

[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.

:rofl: :facepalm:

[Maybelater]

[403ep3]

Correct answer is 9 for the second one lol

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

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. :rofl:

[Supa Dexta]

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

[elite]

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.

[Supa Dexta]

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. :nut:

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!!

[dirtsniffer]

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.

[EK69]

http://www.abovetopsecret.com/forum/thread697048/pg23

Yes there seems to be 26 pages on this shit :nut:
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 :rofl:

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)

6/2(1+2)

This is nothing more than an improperly written equation.
Without brackets around the (2(1+2)), you have to write the (1+2) as if it is in the numerator.

=9

Do we REALLY have to go through this all over again?

Weird.. I am late to the party.. There's no ambiguity there. 6 is divided by everything after it. Another way is to rewite the equation as 6 * 1/[2(1+2)]. Answer is 1.
