>>684874352
you're joking... right?
is actually bait?

The issue here is that people think parenthesis and multiplication are interchangeable. While they function the same way, in the context of Order of Operations, they are not interchangeable as parenthesis always comes first. Anything next to the parenthesis ( in this case, 2) gets distributed into the parenthesis via multiplication before you can proceed down the PEMDAS order.

OP, that's not how you start an argument. THIS is how you start one:

Finally someone with something above the GED the edgy /b/tard have.

>20/ 2(5x5)

This is where people falter. They think division comes first because it appears before the multiplication. But in this case, the multiplication is actually a parenthesis which, according to PEMDAS, comes first. Not only do you solve for what's inside the parenthesis, but anything outside the parenthesis ( 2(10) ) also counts as a parenthesis operation. Hence it becomes 20

>20/20

>>684876678

A because in B, you turned the parenthesis into a multiplication sign when it should remain a parenthesis and the 2 is distributed into it.

The distributing number is canceled out once it's divised. The quotient should not have a two before the parenthesis.

This is too vague and improperly written.

or
(20/2)(5+5)=100
where
20/2(5+5) doesn't provide enough information to determine the proper order of operation.

That only applies to whatever lies INSIDE the parentheses.

You formatted it wrong. The (5x5) should be in the denominator beside the 2 because anything next to a parenthesis stays with the parenthesis.

If that (5+5) was included in the denominator, it would be 1

biggest retard in the whole thread right here

>>684877484

i agree

>>684872944
First, this problem is written extremely poorly. It should be written like this 20/(2(5+5)). If you think about it, the 20 is in the numerator and the 2(5+5) is in the denominator or else the problem would be written as (20/2)(5+5), which it is not. Therefore the parentheses I added makes sense.

So doing the math is now easy, just PEMDAS it out.
=20/(2(5+5))
=20/(2(10))
=20/(20)
=1

OR

=20/(2(5+5))
=20/(10+10)
=20/(20)
=1

Same thing. The answer is 1.

>>684877517
Sorry to kill your vibe, but the "smart ass" is correct

Jesus christ you're actually all 14 aren't you?

There is no way that you would end up with 5+5 in the divisor.

>>684877484

it can't be the former of the two because adding parentheses makes it an entirely different equation than the one written

Therefore, proper notation for this problem is as such:

Using distribution properly it's

20/2(5+5)
20/2(10)
10(10)=100

You're approaching the equation by looking at the parentheses first, which is a bad habit that I blame schools for. Distribution is a neat trick, but PEMDAS means you have to solve the equation from left to right, starting with 20/2.

is the problem 20/2(5+5) the same as (20/2) * (5+5)?
If so the answer comes out as 100.

>>684872944 100

>>684872944
you're all wrong
20 / 2(5+5)
20 / 2(5) + 2(5)
20 / 2 (5) + 2(5)
10(5) + 2(5)
12(5)
17

>>684880570
yes the calculator is right strictly. but when writing it out 2a and 2*a are not always the same thing. omitting the * generally groups the terms together, so 2a=(2*a). The real fault is writing the expression in a way that can be interperetted in more than one way

>>684881128
Let's turn the divison into a multiplication such that we can evaluate in any order:

(20) * (2^-1) * (5+5)

Now evaluate it.

>>684881171
Fuck I mean yes look at the parentheses first, but don't consider numbers outside of them first as well.

This equation is the same as 20 / 2 * (5+5), but the way it's phrased throws people off.

>>684881171

ugh dude just go look it up, distribution comes before regular div/mul because it falls under the parenthesis order

>>684881051
you realize 2(5+5) is not the same as 2(5)+2(5) right? You seem to think it is.

>>684872944
It's 1

>the goyim expect me to read from left to right

>>684881180
I mean, technically, that's not how you're supposed to right it, but yeah, it is.

>>684880923
That is making the division into a fraction. If it was a fraction, the answer would be 100. But it's represented as division, which is two separate numbers. Thus making it 1. The way it's represented makes a difference. Yes, fractions are division, but when it comes to calculators, they're picky like that. 20÷2(5+5) is one, but 20/2(5+5) is 100.

>>684881470
I looked it up. I'm correct. Fuck this bait.

Strictly is all that counts. If you want them grouped first, no matter where it is, it should have parentheses. I was actually taught to do that in algebra for that reason.

>>684881471

lol what? 2(5+5) is simplified to 2(10), then solved as 20

>>684881471

these are exactly the same fucking thing. I don't even know where you start with you.

>>684872944
You distributed the 2 properly, but then you just left it there running amuck.

Sloppy at best.

Try again.

>>684881619

you are fucking retarded then if you think you found anything that proves you are right

>>684882005
You need to divide 20 by 2 first. Parenthesis in PEMDAS only means what is inside the parenthesis.

>>684881180

if you don't know about how 2(5+5) counts as a full parenthesis item then OPs equation works, if you are like 90% of the people in this thread its 20/(2*(5+5))

>>684882074
They actually aren't. They lead to the same answer, but in an equation, they can lead to vastly different results.

i understand why it thinks its 100 now, thread was good learning experience

so does that mean 1+1=200?

>>684882942
>s th
sortaof

>>684881951
yes but it can be argued that omitting the * does group them together, without the need for parentheses. so ab/cd = (ab)/(cd), not (abd)/c as a calculator would assume. so i would interpret the OP question as 1. obviously OP's expression should be written unambiguously

>>684872944
this is why you arent a mathematician

It just lacks information. You need parentheses. It could mean 20/(2(10)) or it could mean (20x2)(10).
The are plenty of different fancy acronyms, PEMDAS, PEDMAS, BEDMAS, BIDMAS.
Regardless, if you were to solve an actual fucking problem, like engineering problem, the order would be obvious anyways as long as all your braincells are functioning.

Dipshits. I learned this math in fifth grade.

20/2(5+5) ------ distributive property
20/10+10 ------- now pretend this is a fraction, add 10+10
20/20 ------- do math now
1 is your answer.

PEMDAS is not the law, it is just a helpful set of guidelines for solving most arithmetic problems. So you can't cite it as a reason for anything.

This post, even aside from the stupidity that went on with the second line there, is blatant bait because of this usage of the division symbol. It could be interpreted as:

>20 / (2 * (5 + 5)) = 1
or
>(20 / 2) * (5 + 5) = 100

and neither option would be incorrect. The usage of ÷ as an operation is inherently vague. We cannot decide on the answer to this question because the question is made poorly.

So stop making threads like this you shits.

Its interpretive. The answer could be 100 or it could be 1, depending on how you view the equation.

1+(1*0.5)

>>684876171
>What is the Cost of a book that costs 1$ plus half of its price?

Ah, the tricky vague "its". You could be referring to the book, in which case it would cost $2, or the dollar, in which case the book would cost a $1.50. Clever.

I love wasting my time

Would these two items not be mathematically equivalent. Then solve. At least this is what I remember from basic Algebra.

I see how I could be wrong considering there aren't parenthesis around the entirety of (2(5+5)), but I'm just assuming that converting to fractions would be a viable solution in substitution for the division sign.

>>684884495

seriously fucking hate this site and how i get drawn into these threads but at least today i learned something

>>684884439
Calculators adds automatically parenthesis on 20/2.

The real answer doing division first is:

20
__________
2(5+5)
