1. You don't know the answer, which means your ignorant.
2. You know the answer and are trolling, which means your a fucking idiot.
So, at best you are ignorant, and at worst you are a fucking idiot.
Take your pick, but understand that arguing with an ignorant person or a fucking idiot puts you on the same fucking level as whoever the fuck you think is wrong here.

If what you say is true you should be aware that multiplication and division have the same priority.
>>604766541
>>604767563
>>604767589
20 / 2(5 + 5) = 1
20 / 2 x (5+5) = 100
When you miss out the x symbol, the multiplier applies to the brackets which follow.

>>604768018
They don't have the same priority.
Parenthesis
Exponents
Multiply
Divide
Add
Subtract
In that order.
Its established so retards don't fuck shit like this up.
>>604768424
it's also PEDMAS too ya dumbass. M and D are the same priority.
in step 2, youve got 20 / 2, which is 10, then you've got *10, which is 100.
>>604768381
well that will happen if you put the (5+5) underneath for.... no reason? I mean I could put a 7 in the middle of it all and change the asnwer too, but that would just show that I'm a dumbass.

Okay you FUCKING SHITS!
Here's how it is.
20 ÷ 2 (5+5)
Now operations within brackets are always resolved first, everything inside a set of brackets is considered to be one number. Therefore.
20 ÷ 2 (10)
Which in human speak is
20 ÷ 2 x 10
now division and multiplaication is resolved at the same time, starting from left to right (it doesn't actually matter, you can start from the fucking middle if you want, but this is fucking America, we read left to right) we go.
20 ÷ 2 x 10
= 10 x 10
=100
Not that fucking hard is it?
>>604769515
It's actually a complex variables problem, which is after calc 2 and 3 in most colleges. Just fucking with you m8.
>>604767727
Fucking idiot.
I'm a graduate in the same degree, don't fucking shame the degree you're trying to get.
For all of those people who cry "PEMDAS!!!"
Just understand what PEMDAS actually is.
P E M&D A&S
you follow this from left to right in a math problem. Always do Parenthesis first. Then the Exponents. Then Multiply and Divide as needed from the left side of the problem to the right side. Same with addition and subtraction.
Inbreeds...
>>604768749
You need to get your head out of your ass you dick fuck. Its PEMDAS it always has been. This is elementary school level shit. This isn't theoretical math you do it in this order because addition and multiplication will be the same no matter which number is in which place.
2+1=3
1+2=3
21=1
12=1
The same works with multiplication and division. If your talking about graphing some shit maybe you have an argument but with a simple no variable equation like this you are wrong fuck stick.
>>604769442
Don't be retarded, division/multiplication have the same priority, but when both are present you have to solve them from LEFT TO RIGHT, so you have to do 20/10 before you multiply by 10

I'm not even reading the other comments, just hopefully reiterating that you perform PARENTHESIS equations first, then exponents, then multiplication, THEN division.

>>604770461
Reiterating that you're stupid, operations of the same priority are solved left to right.
Use the fucking Google.
>>604768749
But we still have Parenthesis so you still must eliminate the parenthesis first, which in this instance requires multiplication first. once the parenthesis is gone, you can continue and in this case there is only division remaining
>>604766207
Do people really not see his mistake? jesus christ, and I thought I sucked at math
>multiplying by 2 twice, even after he clearly did it the first time
>HURRRR HAY I WUNNA ARGU ABUT IT CUZ I M GUDZ MATHMETIERMER
>>604770654
If there are parenthesis, they come first. You must eliminate the steps in the proper order, so first you must multiply down to eliminate the parenthesis, then you can continue with all same level operations, which in this case requires only to divide twenty by itself, equaling 1.
fucking idiot
>>604770945
Don't be stupid, you solve the parenthesis the moment you do 5+5, there's no more operations after that in the parenthesis.

>>604768088
By the very definition of the equation, the second version of your equations are correct. The first one doesnt exist.
Source: Literally every math text book ever.
>>604771284
But in order of operations you would solve the entire equation inside of the parenthesis first before multiplying or adding anything outside.
>>604771149
You ADD 5+5 to solve what is inside the parenthesis.
If you can't do basic math at least use tools like mathway or even your calculator.
Or use google http://lmgtfy.com/?q=20%2F2(5%2B5)
it's 100 you fucking stupid american idiots.
>>604771220
First you need to dissolve the problem inbetween brackets. 10 inbetween brackets must be done times 2, and after that you divide 20 between 20, resulting in 1. That calculator clearly hasn't been into high school.
Sorry if I got any terms wrong, that's because I don't get maths in english, not from an english country.
20 / 2 * (5 + 5)
20 / ((2 * 5) + (2 * 5))

But you can't work with numbers outside the parenthesis (aka 2) until you solve the operation inside the parenthesis (aka 5+5), after you solve 5+5 you will get (Divison) (Multiplication) and then you PEMDAS left to right.
Jesus Christ every online tool, calculator and math textbook says you're wrong, stop being so dense and test it yourself.
>>604771792

>>604771682
You cannot do 2*10 until you do 20/2 because the division comes first, is on the left side of the operation.
Left to right, left to right, left to right.
>>604771792
if the equation was being solved left to right then why did we do 5+5 first?
20/2(5+5)
20/(10+10)
20/10 + 20/10
2 + 2
4
how can you all be this fucking stupid
>>604772010
how can the division come first if multiplication and division are at the same level? multiplication can therefor come first
New problem.
>>604766207
the answer is write out your equation properly you piece of shit
>>604771622
No. What you would do is add 5+5. Then you are left with:
20 divided by 2 times (10)
Now if you follow order of operations and go from right to left like usual, you would do 20 divided by 2 first, which leaves you with 10. Now you have 10(10) which equals 100.
if everyone would stop being dumb, you would realize simply that the equation is looking for ultimately what would end up what the 20 is being divided by. in this case, it is being divided by a clusterfuck. so you must use the order of operations to solve the clusterfuck and then we can find out what we are dividing 20 by, which in this case is 20, so we get 1
>>604768381
You input that wrong. You put 20/(2(5+5))
>>604772089
Because it's inside the parenthesis? The P of PEMDAS means solve what is *inside* parenthesis first, which is ONLY 5+5, if you had a (2(5+5)) it would be a different matter, but as it stands its 20/2x(5+5) => 20/2x10
Left to right is for operations of the same priority, when you have a multiplication and division together or addition and substraction
>>604772186
no complex analysis pls you're triggering my PTSD
>>604772151
If they didn't teach you that when you have two operations of the same priority you have to solve them from left to right go back to school.
>>604772520
Which then leaves you with 2(10) which equals 20 which is then divided by the 20 that was not participating in the parenthesis party which then equals 1
you think this is twenty DIVIDED by 2 TIMES the quantity of 5+5. but it is 20 DIVIDED by 2 times the quantity of 5+5
so fucking solve that shit and then divide it by 20
WHICH EQUALS 1
>>604766207
20 / (2(5+5)) =>
20 / (25 + 25) =>
20/50 =>
(2/5)*(10/10) =>

but the equation is not 2(5+5) it's 20/2(5+5), you cannot just forget the 20/ is there, 2(5+5) is not a single operation, the P of PEMDAS only applies for whatever is INSIDE the brackets not outside, so only (5+5) has priority over anything else, after that it turns into 20/2*10.

>>604776017
Do you even understand what you're typing?
>Nope. Resolve terms before performing further operations on them. /thread
EXACTLY, you resolve 5+5 before performing further operations of them, once 5+5 is solved then you move on with the PEMDAS, using LTR for operations of the same priority.
20÷2(5+5)
20÷2(10) or 20÷(10+10)
20÷20=1
You have to add what is in the parenthesis and distribute the 2 into the parenthesis or vice versa before doing the rest. Simple math shit, anything else is wrong.
>>604776031
What? They don't mean the same thing at all, lmao. If you see the divide icon (ill call it % cuz it looks close) you do it right away
So 6 % 3 * 2 means you go 6 % 3 = 2, 2*2 = 4
But when you use the / you set up a fraction:
6/3*2 =
6

3*2
6

6
1
>>604776232
why would you
>"distribute the 2"
instead of following the order of operations?
>>604776232
You're not supposed to group 2(5+5) and leave the 20 hanging, you're supposed to group (20/2)(5+5), you cannot arbitrarily take the 2 out of 20/2 and use it for 5+5
>>604772294
The problem is no one really knows if the two should be distributed into the 5+5 or not.
>>604775618
This would be correct if we were using variables, but we're not so go away.

Computers dont use the divide icon, what part of both icons meaning the same you don't understand? Get on with the times.
>>604778668
you apparently because the answer is 100
>>604778862
That shows the opposite of what you said
>>604766207
you are dumb
>>604779047
Yes, they are very real. I can post the solutions if you want them.
>>604778497
well I think they're all in the complex space, which contains all real numbers, so yea
>>604779042
Yes, it might be hard to solve if you didn't do any math after school (sorry, don't know American school system), but they're definitely solvable.
>>604779091
I said it equals 100 you dense mother fucker and it shows 100 not 1. you okay?
>>604779218
meant to quote >>604779042 ?
>>604779218
Sure.
>>604779047
>>604778618
lmao ok then smart guys why is
2 + 4 6
 =  = 3
2 * 1 2
but PEMDAS remember, D, division
2 + 4 (divide sign) 2 * 1 =
2 + 2 * 1 =
2 + 2 =
4
>>604779497
Yeah, I responded to the wrong post. Thanks for catching that.
The 'divides icon' is called an obelus by the way.
>>604766776
ofc its 100
20/2*10 = (10*20)/2 = 100
It depends on the way you look at it. It can equeal either.
BUT if you put it the way the picture says, which is 20÷2(5+5) it equals 100 because of the order.
And
20
 equals 1 because if the order.
2(5+5)
STOP ARGUING OVER STUPUD MATH
>>604779886
THANK YOU FOR PROVING MY POINT!
The divides icon is a DIFFERENT THING than setting up a fraction, the /.
>>604769633
you say it's barackets first.
meaning 20 ÷ 2(10) =
= 20 ÷ 20
= 1
wow there are some dumb fucks here

This type of mathematics is rarely used in real life. I've used the gamma function but only in the real domain. And imaginary numbers are only used in the Laplacian domain when calculating system stability or instability.

STFU math loser
its ALWAS left to right when multi/div
its CLEARLY 100...
20/2(5+5) is clearly (10*20)/2...
>>604780529
Didnt you see the calculator above? It clearly shows how I'm right.
It's 1.
PEMDAS bitches
20/2(5+5)

1
>>604780712
Didn't you read the citation? It clearly shows you're wrong
>>604780795
20/2(10) = ((10)20)/2... still 100
>>604780888
this thread is a waste of good trips
It can be read 20/2*(5+5) or 20/2x where x=5+5. Simplify prior to substituting x and you get 10/x. 10/(5+5)=10/10=1. Proof that mother fucker. Maths is broken.
>>604780712
Except you're fucking retarded lol. They are, in fact, the same fucking thing. When you used the obelus, it's the SAME as you used a slash, except using obelus on that PARTICULAR calculation you saved time instead of using ()'s. Learn your shit, shut the fuck up.
>>604780391
>This type of mathematics is rarely used in real life.
That's irrelevant to the problem. A large amount of math is pure math.
Imaginary numbers actually have large applications in complex potentials for fluid flow problems, electrical engineering, and quantum mechanics. Just because you've seen few uses of it, doesn't make them not useful.
>>604780959
It's 20 divided by 2 times 10. Multiplication comes first.
20 divided by 20. That's 1.

Sure, keep telling me how those are the same. Here's a hint, open up the calculator app on your iPhone and type 1 + 2 obelus 4  1 and see what it says. I'll wait.

This same image in the OP has been posted every single day for the past 3 days and you're the first one I've seen who actually admitted that his math was wrong.
Props to you!
can we please stop using ÷ forever
>>604781570
What the.. This proves my point I'm wasting my time with you. Here's one last effort; instead of obelus, using slashes, the calculation would just be (1+2)/(41) = 1
With obelus, we eliminate the need for (). Like so;
1+2
 = 1
41
There we have it, faggot. Now shut the fuck up.
Why must you people argue like children? It's simple math. Google it. Either use BEMDAS, PEMDAS, or you're just a straight DUMBASS.
Lets do this shall we?
Parantheses! There is one set of parantheses. Lets solve what's in there! (5 +5) = (10)!
Exponents! None of that crap
Multiplication&Division! Okay, since there is more than one case of multiplication and division, you go from left to right! 20/2 = 10
10(10) is now left. You see now that there is only one option left. Multiply! 10*(10) = 100!

Certainly. That said, I usually get these right but did end up with 1 initially. I didn't spaz out like some of these retards, but I did get it wrong. It's nice to be wrong and realise it sometimes.
Answer is 1
Check it
20 / 2(5+5) = ?
20 / (2*5+2*5) = ?
20 / (10+10) = ?
20 / 20 = 1
20 / 2(5+5) = 100 / *20
2(5+5)=2000 /2
(5+5)= 1000
??? what the ever living fuck
put em in a coffin #SQUUUAAD
>>604787412
20 / 2(5+5) = 1 * 20
2(5+5)= 20 / 2
(5+5) = 10
I made the reverse example with 100 to show you the error of your feeble ways. 1 is the answer.
Also, Captcha: Ynagr.
>>604766207
Maths rule is brackets go first, so 5+5 plus 20/2 = 20
Senior Mechanical Engineer here, took calc 5 so master race of all you tards. Just do the simple check.
>20/2(x+5)=1
>20/2=x+5

>x = 5
when you set it to 100
>20/2(x+5)=100
>20/2=100x+500
>10500=100x
>490=100x

Parenthesis first and addition after multiplication.
And inserting 1, evens it out. 100 doesn't.

>>604791403
I think I disagree, gentle sir, but even Google (which works with parenthesis and the operator precedence) agreed. And inb4, I calculated it on my own before. Come on, it ain't that hard.
