Important Math Question

[Ordukai]

Guys, what does 6÷2(2+1)=?

This problem has been keeping me up at nights, I need a conclusion to my math confusion.

[KeyWii]

6/2(2+1)=

6/2(3)=

3(3)=

3*3=

9

[UnknownMurder]

6÷2(2+1)
6÷2x3
6÷6
1 Your Confusion Conclusion?
You were tired.

[Adjective]

PEMDAS:

PARENTHESIS
EXPONENTS
MULTIPLICATION
DIVISION
ADDITION
SUBTRACTION

6÷2(2+1)
6÷2x3
6÷6 =
1

I know for a fact that's wrong vrai. KeyWii is right. You have to see it as this, Parenthesis - Exponents - Multiplication/Division - Addition/Subtraction. When it comes to Multiplication/Division or Addition/Subtraction You read the equation from left to right whichever comes first.

The answer is 9.

[Sebro]

Wow you didn't know the answer yourself...why ask a forum? To make me believe in humanity again, finish this: (x*-9)-(-9)=36. Find x

I don't think I'm wrong, conveniently UM also got the same answer.

Great minds think alike.

[Ordukai]

The answer using Pemdas is correct. You'll find that 9 is the right answer on tests and even your calculator if you care to consult it.

Parenthesis, exponents, multiplication/division, addition/subtraction. You do multi and divi on the same step, left to right.

So 6÷2(2+1) = 6÷2x3 = 3x3 = 9


Same dealyo with addition/subtraction, perhaps a bit more obvious.

Wrong way: Doing addition BEFORE subtraction, regardless of their position.
2-3+1+1+1= 2

2-4+1+1+1

2-5+1+1

2-6+1

2-7

-5


Right way: Working subtraction and addition in the same step, from left to right.

2-3+1+1+1

-1+1+1+1

0+1+1

1+1

2

Hopefully that clears things up.

This middle school level trickery. My Calculus teacher would bitch slap me for getting this wrong...

[Jack McIntyre]

Lol I was about to say can we all just agree to say, fuck this math problem and go on to kill some marines or xenos. We all got more important things in our lives

[Sadokist]

math? PFFFFF LEL nope nope nope

[bustered1]

I've taken too much algebra and trigonometry classes to forget the stupid order of operations. I never got to take calculus sadly, but my major doesn't require calculus heheh.

[TR-BlackDragon]

6/2(2+1)=

6/2(3)=

3(3)=

3*3=

9

This is correct. I checked it with my damn super calculator. Correct answer is 9. So the above math wrote out is spot on.

[Minijar]

Actually, I'll have you know its:
Brackets
Indices
Division
Multiplication
Addition
Subtraction

[Pillow]

What are indices?

The answer is 9.

This is the answer.


It goes like this:

Brackets
Square Brackets
Exponents / Indices
Division / Multiplication
Addition / Substraction

If you prioritize one over another, you are fucking it up, you are supossed to do from left to right all the equals, one by one.

Like: 2+2-3= 4-3 = 1

What are indices?

On a square root, the number that indicates if it's Square, Cubic, etc... Root.

And math problem? Why are you guys even having trouble with this crap? It's fucking 7th grade shit.

Alright. Time to go to Marine Academy!

Two aliens joins with a loner alien.
Three groups out of two aliens joins together.
Every aliens scatters as soon as you enter the hive.
You were only able to kill ONE alien.

[Ordukai]

Three groups out of two aliens. What.

[Pillow]

SOOO indices are exponents... interesting name.

[Kyrac]

12 divided by 0.

Wow you didn't know the answer yourself...why ask a forum? To make me believe in humanity again, finish this: (x*-9)-(-9)=36. Find x


3

(-9x)-(-9)=36
(-9x)+9=36
(-9x)=27
-x=3
x=3

I couldn't resist, the math nerd is strong in me.

[Pillow]

(-9x)-(-9)=36
(-9x)+9=36
(-9x)=27
-x=3
x=3

I couldn't resist, the math nerd is strong in me.

actually if your math is correct, which I am not entirely sure because equation is unclear and implies an x squared variable, then x would actually equal -3 because when you switch the sign on the x you have to do it to both sides.
