2+2×2=?

[Shurik]

Ok, so my buddy and I had a pretty hefty 300 dollar bet going over this tricky equation. 2+2×2=
I say that's the answear is 6 due to multiplication and division always has to be done first.
He says the answear is 8, because he over looks the multiplication rule and just adds it in the order it is. Everyone else we asked at work they all replied with the 8.
Is it me tripping that the answear is six or everyone else is being dumb?
Please state your answear and explanation.

yahoo says 6 still looking for Y

[T-MOS]

when plugged into a calculator as stated 2+2 x 2 the answer comes up 6

[soulstealer]

Based on the commutative property of addition which multiplication, division and subtraction specifically lack... IE 2+3+4 is = 4+3+2 but 2*3*4 is not = 4*3*2 just a proof that Order of operation is important.

And the order of Operations: PEMDAS as an acronym

First: Parentheses
Second: Exponents
Third: Multiplication!!!!!
Forth: Division
Fifth: Addition!!!!!!
Sixth: Subtraction

So yes in a theoretical environment you are correct but if its being applied such as:

1 group is 2 pallets and we have 2 groups and they are sending us 2 more groups how many pallets do we have...

than 2 + 2 x 2 is appropriate disregarding the order of operations is appropriate.

[stack_it]

I hate math y did I click on this? I came up with six tho

I would write that (2x2)+(2x2)=8
or (2x2)x2=8
so, no, it's not appropriate...but incorret conversion of words.

answer is 6

i think he meant to say that 1 group= 2 pallets, we have 2 groups, and they are sending us two more pallets(instead of two more groups)

[Shurik]

Ya I tied to google it and use the TI calculator and it all comes up with six. I'm not sure how else to prove it to them. They say there is no parenthasis around multiplication but there is also none around the +
In that case you automatically plug them in yourself around multiplication and turns out to be 6

[Kratos]

i think he meant to say that 1 group= 2 pallets, we have 2 groups, and they are sending us two more pallets(instead of two more groups)

that would be 2x2+2=6 and would also be same as 2+2x2=6
that's why order of operations is important
if that was what he was saying, he would have proved concept, rather than an exception to the rule

[Phate]

my bad, i didn't read what he wrote, i just thought he was writing a real world example to prove it, lol

[hugovsilva]

Multiplication has priority over addition. So its like this:

2+2x2= 2+4= 6

[gixxerboy1]

6 is correct

[soulstealer]

that would be 2x2+2=6 and would also be same as 2+2x2=6

You are correct it was a fault on my part...

[Phate]

anybody want to try this one

square root(x^2+y^2)

[mho]

The rule of order of operations states that multiplication comes before addition in an equation. Therefore the you multiply 2x2 first, then add 2.

2+(2x2) = 6

[mho]

anybody want to try this one

square root(x^2+y^2)

x+y?

[soulstealer]

anybody want to try this one

square root(x^2+y^2)

|x+y| give me a break =P that is if ^ represents an exponent

[soulstealer]

x+y?

Its absolute value as it was not stated that the number is non negative so it could be any real number hence |x+y|

[Phate]

x+y?

you'd think so, but no

plug in numbers and you'll see why

let's say
x=9
y=9

then square root(9^2+9^2); square root(81+81); square root(162)=12.72, but when you use x+y as the answer you get 9+9=18

18=/(is not equal to)12.72

well than I'm a retard lol

[jfalco]

Wow, easiest $300 you ever made. Can't believe your friend bet on this.

[IM708]

The answer is 6 based off PEMDAS, your friends are retarded, end of story.

[Shurik]

Hell ya just collected my money and damn those benjamins smell good. Lol

[DSM4Life]

multiplication first
2+2×2=
2+4=
6

[Shurik]

My coworkers are still coming up to me with their cheapy calculators and multiply it like this.
2+2=4×2=8
They just dont get the point and how it works. This is 3rd grade math so I dont know whats wrong with some people.

multiplication is commutative... how is 2*3*4 different than 4*3*2??? oya, its not.

[DCannon]

i got 7

lol!

[DCannon]

The answer is 6.

[ronan the barbarian]

it should be bracketed cus 2+2x2 doesnt make sense,unles you know the equation starts with the highest domineering function.in this case its x and not plus.

so if it was written out by a scientist the equation would be 2+(2x2) = 6

WTF are you talking about. Scientists know the order of operators and in my experience most scientists like to do things the easiest possible way that works, so in a simple equation like that they would not bother with unnecessary brackets.

(2+2)x2=8

Multiplication comes before division.

[jfalco]

Multiplication comes before division.

No it doesn't. They are the same thing and they are done at the same time.

Just like addition and subtraction. Doesn't matter which order you do multiplication and division. Answer is the same.

(2x2)/2 = (2/2)x2 = 2

We can thank people like that to help balance out this economy a little bit.
I will spend this money wisely. Test/deca cycle. lol
