Math Problem

[Krayz]

10 + 10 x 0

[GHEZ119]

As I was first, 100% of the poll agree'd with me. Yay, egofood.

/sleep deprivation

EDIT: I was wrong, I forgot BODMAS. :B I suck.

[DrugstoreCowboy]

wtf is bodmas LOL

[Krayz]

Extra Credit:

48÷2(9+3)

[kisler]

48÷2(9+3)
48÷2(12)
48÷2*12
24*12
2*12*12
2*144
288

[GHEZ119]

I got the division one in Chat. ^_^ I remembered BODMAS with that one, yay. :D

Brackets
Order/Index (Depends upon BODMAS/BIDMAS, I think BIDMAS is more recent.)
Division
Multiplication
Addition
Subtraction. :D

[Patashu]

Brackets
Juxtaposition (e.g. ab)
Division/Multiplication (e.g. a*b)
Addition/Subtraction

[MasterWholigans]

Here's one for ya:

6÷2(1+2)=?

Is it 1 or 9?

[kisler]

ohey, did this one on facebook.

6÷2(1+2)
6÷2(3)
6÷2*3
3*3
9

pretty sad that about 40% of the answers are 1.

[GHEZ119]

That's 'cause people suck. :B

[Krayz]

to be honest, these are all terribly defined problems, with the exception of the first. You shouldn't ever come across something like that outside of this type of thing or if your teacher is cruel. It should always be very clear what order to do things in without relying on the reader understanding to go left to right.

[kisler]

to be honest, these are all terribly defined problems, with the exception of the first.

very true. first was probably the most common, as it could actually be application of a formula or definition. rest are "thought required" and could be rewritten more clearly

[Jonny]

anything multiplied by 0 is 0

[xMUSICxMASTERx]

its BEDMAS for me lmao

So Pat uses BJDMAS? I think we have a winner... That can't even be pronounced properly? I mean, PE, BI, BO, yeah... But BJ? D:

[Patashu]

I go to sleep in my bajdamas and a nightgown

[sallygwizz38]

i use PEMDAS

[Nocturne]

i use PEMDAS
THIS. shit everyone learns so differently.


Parentheses, Exponents, Multiplication/Division, Addition, Subtraction

[kisler]

One that's been slowly circulating Facebook:

1+1+1+1+1+1+1+1+1+1-1+1+1+1+1+1+1x0

Roughly 1/3 of people have the answer right there.

[Patashu]

ok normally these are stupid ambiguous problems (e.g. multiplication and division priority is ambiguous esp. with regard to implied and using the symbol) but this one only has one answer unless you're using an old calcualtor or something

[Nocturne]

WolframAlpha (http://www.wolframalpha.com/input/?i=10+%2B+10+x+0+)

[kisler]

WolframAlpha (http://www.wolframalpha.com/input/?i=10+%2B+10+x+0+)

Extension is incredibly useful. http://www.wolframalpha.com/downloads.html

Also, there's a guy making fun of Americans who can't add on that FB poll now. In Spanish, though.

[SkRAWRk]

WolframAlpha (http://www.wolframalpha.com/input/?i=10+%2B+10+x+0+)

Yes. <3 This is beyond awesome and a really useful site. xD

EDIT: Nice colours, Shaun. <3

[kisler]

Here's another one. Only the strongest can answer it.

[Internet]

Why isn't 36 an option?
That's obviously the right answer.

[trunks55]

/penis (edit: it's the answer to most things on the internet)

[kisler]

Well, clearly the correct answer is ⑨.

[Nocturne]

Damnit i just got Guru'd by Touhou math.

14. It's 14.

I just got mind****ed on the highest level.

[kisler]

New problem I guess. It's from Facebook again.

5+5+5-5+5+5-5+5x0

The correct answer is 15.

4,945 people voted 40.
17,004 people voted 20.
147,587 people voted 15.
But alas, 226,315 people voted 0.

New problem:



a² + b² = c²

solve for q.

[cheezpuffs]

ones that involve x0 ALWAYS annoy me! having said that, BODMAS / BIDMAS / BEDMAS kicks in, and it sure causes chaos! XD

[SkRAWRk]

New problem:



a² + b² = c²

solve for q.


q is i. Problem solved~

3x-14=1,000,984,672,785,892,905,309,684

[X]

This thread shows me that 30% of people that browse the forums are stupid =D

[Nocturne]

3x-14=1,000,984,672,785,892,905,309,684

x = 1000984672785892905309698/3

x= 3.33661557595297635103232666666... × 10^23

or x= 333661557595297635103232 + (2/3)

[DefTeaMachine]

my mind scattered before i could even begin to read those numbers.

I love your overuse of memes in your posts. Brightens up my day


Whats the square root of 69?

[kisler]

Whats the square root of 69?

About 8.3

What is the boiling point of water at 0.35 atm?

[cooke71892]

Nocturne, you win

[FlashDualist]

whats 5 divided by 0?

[Nocturne]

Nocturne, you win

:D :D

[Moop]

How can you be this bad at math? we learned this in grade 4.

[DefTeaMachine]

whats 5 divided by 0?



FUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU UUUUUUUUUUUUUUUUU

[AMasalone]

1. 48/2(9+3)
First: (9 + 3)=12

48/2(12)

Second 2(12)=24

48/24 = 2

The solution is 2


2. 62(1+2)

First 6/2(3)

second 6/6

Solution is 1

[./. means divide .(.) multiply]

[kisler]

1. 48/2(9+3)
The solution is 2

2. 6/2(1+2)
Solution is 1

Both of those answers are incorrect. For the multiplication to go before the division, the entire denominator needs to be bracketed.

[kisler]

whats 5 divided by 0?

Loool. We actually had to discuss this in calculus because some people didn't understand how it's undefined. A bunch of people STILL don't understand indeterminate forms in that class, which was how this discussion first came up.

[DefTeaMachine]

lol calculus. they used to offer that in my high school
they changed it because "In Pine Forest and West Florida combined, there were only 13 students who could take the class"
translated: your too stupid.

[Vote4DJz]

my answer is wrong I should have use the rule PEMDAS

10x0=0 10+0=10 now 10 is the answer

[housedog]

Loool. We actually had to discuss this in calculus because some people didn't understand how it's undefined. A bunch of people STILL don't understand indeterminate forms in that class, which was how this discussion first came up.

But did you discuss what the answer to this is on the set of Complex numbers rather than the set of Reals????????

[Litodude]

your too stupid.
his too stupid

[kisler]

Yeah, but barely. AP doesn't test complex analysis to my knowledge, so we don't bother.
