Is it 1 or 16?

[Anonymous No.10854667]

>>10854662
it's 1.5 since 8 / 2*2 + 2 = 8/6

16 because the steps of math. operations you learn in elementary school.

[Anonymous No.10855655]

>>10855321
>operations you learn
Key word: YOU

Some people learn the BODMAS method, which apparently gets you 1.

[Anonymous No.10855717]

>>10854662
It's 1.
Anyone who says other wise is a retard, because multiplication comes before addition.
For example, >>10855321 is a retard.

If I something written this way, I would assume 1 to be honest. You see people being lazy like this all the time in physics like E/kT or p^2/2m

[Anonymous No.10855774]

>>10854662
ambiguous notation
there is no "answer"; it is a meaningless sequence of symbols

[Anonymous No.10855778]

>>10855773
How would it properly be written?

[Anonymous No.10855909]

2(2+2) = (4+4)
8 ÷ (4+4) = 1

[Anonymous No.10855956]

It is somewhat ambiguous but the right side of the expression should be treated as one term in my opinion, which makes the division symbol the main operator. So the answer is 1

This but brainlets and normies will continue to argue none the less.

Implied multiplication fags BTFO.

>>10855778
>(8/2).(2+2)=16
However, as we know that we should solve from left to right, the parentesis in 8/2 is ommited.

For the result to be 1, it would have to be written as
>8/[2.(2+2)]=1

[Anonymous No.10856419]

>>10854662
Neither. That division symbol is retarded and ambiguous and should stop being taught.

8 / 2(2 + 2) = 8 / ((2 * 2) + (2 * 2)) = 8 / (4 + 4) = 8 / 8 = 1

Can someone tell me what I did wrong?
I treated the answers given as a equation. Divided both sides by 2, and got a invalid equation both times.

[Anonymous No.10857057]

>>10854662
depends on the axioms.
basically, it is all about the operation priority and the interpretation of faggy division sign.
You could even go for something like this:
[math]8 \div 2 \cdot (2+2) = 8 \cdot 2^{-1} \cdot (2+2) = 8 \cdot \frac{1}{2} \cdot 4 = 16 [/math]

First, remember how division is defined in algebra

[Anonymous No.10857073]

>>10857065
Then rewrite the problem using the rule.
It is easier to see converting it to letters, let a=.... b=.... but I don’t have the space here

[Anonymous No.10857086]

This question highlights the poorly defined rules around mathematical notation, the implicit parentheses around the left and right side of the division symbol is what trips most people up who don't have an office job in which they do math.

[Anonymous No.10857096]

>>10857086
Try letting 8=a, 2=b and working through the proof that
a (dividedby) b(b+b)=1
and
a (dividedby) b(b+b)=16
Are both wrong. I’ll wait for your head to explode

[Anonymous No.10857116]

>>10857096
what's the point of using variables if you already know the answer? beyond that what are you even arguing?

[Anonymous No.10857121]

>>10857116
Because all rules have to hold, such as (b+b)= 2b
Did you try it?

[Anonymous No.10857126]

>>10857086
There is only one term there

[Anonymous No.10857313]

>>10855655
Well that's bullshit then. Math expressions need to be uniquely simplifyable and that property gives you 16.

What is 8 § (2+2), (2 of course)
Now what is 8 § 1(2+2). Is it 32 or 2?
Recall a*b =b*a
Now what Is 8 § (2+2)1.

I'm not sure if this is a joke or people are just memeing.

8/2(2+2) = X

> 8/2(2+2)
> = 8/2(4)
> = 8/8
> = 1

> 8/2(2+2)
> = 8/(4+4)
> = 8/8
> = 1

Brackets get resolved first. Always. Order of operations. For example, you can't do this.
8/2(2+2)
(8/2)(2+2)
Because 8/2(2+2) is 8/(2(2+2)).

bodmas and pedmas is the same thing...

fucking spastic. The reason is Math has been updated to follow newer conventions post 1920's were 1 is acceptable.

[Anonymous No.10857373]

>>10855923
hahaha mate you just absolutely butchered the expression.

The expression is "8/2(2+2)" and 2(2+2) is not by itselft, nor a function, nor directly algebra. It is apart of the expression 8/2(2+2) it makes semse logically that it becomes read left to right the moment we set it as 8/2(4) or 8/2*4.

This convention makes sense seeing as () is just for enabling the plus action to happen first in the expression.

do you see a single variable or constants? It's an expression with operands and operations. Specefically a discrete expression containing positive values.
