Math problem

[DoubleWolf]

This one has been floating around on fb recently. Curious what people here think the answer is...

1+1+1+1+1+1+1+1+1+1-1+1+1+1+1+1+1 x 0 = ?

 

[Corey 'Greyfox']

zero, you multiply any number by 0 and your answer is always going to be 0.

EDIT: Wait no I'm wrong, it's a trick question.

 

[Nihilist]

14 .

 

[Makitoki]

42

whoever finds this a math problem needs to go back to elementary school or get some new glasses.

but i bet its something that gets the adrenalin going for all them fb campers

What means »fb?«

It's not a trick. There is a correct answer, and it IS one of the poll answers

What means »fb?«

Facebook

Facebook

Aah... the evil one... fraud, waste, and abuse...

Ya the answer is 14, the trick is in how the problem is displayed.

14.

No brackets around the 1+1+...

EDIT: Wolfram Alpha confirms this answer.

 

[Danoclese]

well, since there are no brackets around the numbers, we are led to proceed 1 multiplier at a time...so add 1 together 14 times but multiply it by 0 at the end leaving us with 14 as the result....14 X 0(meaning it isn't multiplied by anything) = 14...right? But you can always look at it as 14 X 0 which equals 0 if we take it in that logical order as presented in the equation...so 0 is the correct answer



edit: ok, so my numbers are a bit off but the logic is sound

 

[Pauhe Gunor]

no fing idea where yous are getting 14 from anyhow there is 17 1's, 1 Zero, 15 + symbol's, 1 - symbol, adding and subtracting the sum tallys upto 15 then multiplied by zero

I thought it was 4 but google says it's 14

(1+1+1+1+1+1+1+1+1+1)-(1+1+1+1+1+1)+(1 x 0) = 4
10 - 6 + 0 = 4

 

[kira-red]

amazing.

isn't that question something like a grade four or five level problem?

I'm terrible at math. and, the answer is 14.

 

[Pirx Danford]

Without brackets multiplication and division take precedence.
Meaning that as first action the one at the end is multiplied by 0, so you just have one 1 less to add.
In the end it really is 14

 

[Danoclese]

I thought it was 4 but google says it's 14

(1+1+1+1+1+1+1+1+1+1)-(1+1+1+1+1+1)+(1 x 0) = 4
10 - 6 + 0 = 4

You're changing the equation here by adding the brackets. If no brackets are presented in the original equation, you must proceed 1 number at a time.

(1+1+1+1+1+1+1+1+1+1)-(1+1+1+1+1+1)+(1 x 0) = 4
10 - 6 + 0 = 4

Wrong use of bracket


=1+1+1+1+1+1+1+1+1+1-1+1+1+1+1+1+1 x 0
=10-1+5+0
=9+5
=14... Ans

Lol, yeah, its funny how a situation that requires 0 thinking (or at least should require 0 thinking and everyone should know how to do it w/o a doubt) can make up so many different replies and results.

 

[BlackHawk]

If it is modulo 2 then the answer is 0. If it is modulo 10 the answer is 4... if it is base 2 the answer is 1101 If it is base 10 it is 14. If it is base 16, the answer is E. And so on....
Truth is no one knows.... is a secret.

EDIT: Wolfram Alpha confirms this answer.

If wolfram say it , it must be true...

And how the hell i am supose to reply on that biased poll , there is not the reply 42 ...

 

[Nor Alien]

Bedmas is your friend!! ( Brackets Exponents Devision Multiplication Addition Subtraction ) and 14 ftw!!

Or what Nihilist said!!

 

[Wed]

Nevermind my vote for 17, didn't see the - lol

 

[Argh non Ral]

It's 1110!

Ah well ... shame on everyone who sees this as a 'math problem' and finished the first class of the elementary school.

 

[Usurper]

This is strange...i got 1337

 

[Angel O2 Mercer]

I voted "pizza".

I'm right, you're all wrong.

Sorry =)

I need to correct myself! Indeed it's a serious problem!

Just saw the standing of this vote on FB ... 1.6 million vote for 0 VS. 1.2 million vote for 14!!!!
HELP! I don't want to share this planet with so many primitive humanoid lifeforms!!!

Well, its an attention problem more or less, you have to spot the - for example, not just count 1-s and ignore the last one. Calling it a math problem is a trick.

 

[Luckycharm]

Ok so it doesn't take a rocket scientist to figure out it's 14 but what if it's binary? ;p
