Is the answer is 2 or 0.5?

it's both

that's a effect of quantum physics

6/(3y)=1
6=3y
y=2

This...I took a math test like 5th or 6th grade to determine middle school placement and got placed 1 class ahead instead of 2 because wasnt taught the dot notation for multiplication, just the cross or x. Then like 3 weeks later we learn it. Still hate that day as I could have been done with all my calc classes before undergrad, but I guess the easy gpa boost in college was nice too..

6/3y=1
3(6/y)=1
6/y=1/3
y=18

whats the point of these fucking threads? we get it. the notation is ambiguous. now fuck off.

>ambiguity due to a lack of parentheses is an effect of quantum physics.

At last I truly see.

This is the kind of shit you'd see on facebook with "99% fail" next to it.

Where's the parentheses?

this is why we should use polish notation

2

Parentheses don't change anything. The answer will always be 2.

Fucking western "education"...

6 ÷ 3y = 1
Multiply both sides by 3y
6 = 1×3y
divide by y
6/y = 3
y=2

6 ÷ 3y = 1
Divide both sides by y
6÷3 = 1/y
2 = 1/y
y=0.5

6 ÷ 3y = 1
subtract 6 from both sides
3y = -5
Divide both sides by y
3 = -5/y
y = -1.666•••

6 ÷ 3y = 1
subtract 6 from one side and add it to the other
3y = 7
y = 2.333•••

6 ÷ 3y = 1
subtract 3 from both sides
6 ÷ y = -2
multiply both sides by y
6 = -2y
y = -3

6 ÷ 3y = 1
subtract 3 from one side and add it to the other
6 ÷ y = 4
y = 1.5

6 ÷ 3y = 1
divide the entire equation by 3y
[math]\frac{6}{\frac{3y}{3y}} = \frac{1}{3y}[/math]
6 = 1/3y
y = 0.1666•••

6 ÷ 3y = 1
multiply the entire equation by 3y
18y ÷ 9y = 3y
2y = 3y
Divide both sides by 2
y = 1.5y
divide both sides by y
1 = 1.5

QED

6/3*y=1 | Division and multiplication in order of "left to right"
2*y=1 | Divide both sides by 2
y=1/2

2 you mongs.

math brainlet here
what is the difference between 3y and 3*y ?

>multiply the entire equation by 3y
>18y ÷ 9y = 3y
18y ÷ 9y[math]^2[/math] = 3y
Subtraxt 18y from both sides
9y[math]^2[/math] = -15y
Divide both sides by y
9y = -15
y = [math]-1.\overline{6}[/math]

there is none, that is why y=1/2

How the hell would it be 0.5?

3y / 6 = 1
3y = 1 * 6
3y = 6
y = 2

3y / 6 = 1
0.5y = 1
y = 2

this is my fav

6 / 3y = 1 x 6
3y = 6
3y / 3 = 6 / 3
y = 2

yeah user quantum physics is hard but it's worth it!

Obviously 2, 3x2=6, 6 divided by 6 = 1

3 x 0.5=1.5
6 divided by 1.5=4

6/3y=1
6/3y-1=0
6/3y-1=0 multiply both sides by 1/(6/3y-1)
1=0
CaN YoU TeLl whaT is WRonG wItH thIs EqUAtIoNN? only 99% get this!

Implied multiplication makes this 0.5 you FUCKING niggers.

What's in the picture is not valid mathematical syntax.

[math]1/2 + 1/2 + 1/2 + 1/2 = 2[/math]

[math]2/2 + 1/2 + 1/2 + 1/2 = 2.5[/math]

[math]3/2 + 1/2 + 1/2 + 1/2 = 3[/math]

Meth

Hm, should be more fun to be had. Notation!

fucking brainlets

You have to be 18 to post here

no U

Pretty sure you're asking for this.

[math]{2 a = 1, 2 b = a/2, c/2 = c/4}[/math]

wolframalpha.com/input/?i={2 a = 1, 2 b = a/2, c/2 = c/4}

[math]6/3 y = 1 = 6 y/3[/math]

[math]|(0 +) 1 => 1

1/2 + 1/2 * 2/1 - 1/1 = 1/2, 0.5

(1/2 + 1/2 * 2/1 - 1/1) = 1/2, 0.5

(1/2 + 1/2) * (2/1 - 1/1) = 1

1/2 + (1/2 * 2/1) - 1/1 = 1/2

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

1/333 + 1/2 + 1/333

1/2 - 337/666 = -2/333

1/2 + 337/666 = 335/333

333 + 1/2 - 333 = 1/2

1331/2 = 333 - 1/2 + 333

Nice try faget.
You're literally playing mind games to Veeky Forums because you're not rewriting it properly. Why would you multiply 6 on both sides?

Anyone saying 0.5 has the mind of a six year old.
The answer is 2.

what the point of baiting and bumping this useless thread.

6/3*2 = 4 you faggot

See you in 3 days, kiddo.

Don't summon the RPN retard, OP.

Are you guys all retarded?

Fuck guys ignore this no bully

It's ambiguous.

How is this wrong?

Brainlet here.

what the actual fuck

...

A+ m8

This

every faggot who makes this kind of threads should be sent to auschwitz when it reopens.

Write the equation properly you illiterate fuck.

why in the world would it be 0.5

division and multiplication have the same importance, whichever is left is done first

It looks ambiguous but it is not. There es no rule that omitting a multiplication sign gives it a higher precedence. So the answer is 0.5

This. It's not ambiguous, but it's not pretty look at.

waste of dubz
it is six divided to THREE WAI

He's not wrong, these ambiguity problems are exactly what RPN is a solution for.

6 / 3y = 1

3y (6/3y) = 3y (1)

6 = 3y

3y = 6

3y / 3 = 6 / 3

y = 2

why is it so hard dealing with non fractional division

ebcause at an early age we've seen it like that, and PEMDAS fucks with our perception for which number we multiply/divide first. Either that or the more likely reason is that i'm an autistic brainlet who can't math
