Well /sci/? Are you dumb asf?

> Le ebin brainlets neglecting the left-to-right rule meme

People who say "DUH ITS ONE PEDMAS DUMMY" fail to remember that the you do multiplication/division from left to right, as they are encountered - putting the division before multiplication in the order of operations.

They argue that as D is before M in PEDMAS that division takes priority for some reason

Bitch please

[eqn]\frac{6}{2(1 + 2)} = \frac{6}{2(3)} = \frac{6}{6} = 1[/eqn]

[Anonymous No.8284604]

>>8284559
Pshh, easy

[eqn]\frac{6}{2(1+2)}=\frac{6}{2(3)}=\frac{6}{6}=1[/eqn]

Did you just divide before even multiplying what was on Parentheses?

[Anonymous No.8284616]

Hold on. Everybody hold on. I want to talk about something real quick.

What is with this recent wave of Facebook memes challenging normies with order of operations questions? Does it trouble anyone else that this is a thing?

These have always existed.

[math] a / b(c+d) \neq a / [b(c+d))[/math]

While notation used in schools are shitty, when you write out a division symbol:
[math] a/b(c+d) \longrightarrow \frac{a}{b} \cdot (c+d) [/math]

It's stupid notation but that is how that works.

Yes, but you didn't include a picture of a pretty Korean woman, so it didn't count.

>>8284604
that's incorrect though. The question would have had to read 6 / (2(1+2)) in order for you to move the (1+2) to the denominator. The correct reading would give you

6/2 * (1+2) which = 9

[Anonymous No.8284631]

Oh.

Carry on.

The order for multiplication/division goes from left to right.

I think a better question is

Why is the quality of that image so shit?

Did the faggot run it through an image compressor?

[Anonymous No.8284637]

>>8284596
Wrong, 6/2 is the coefficient of (1+2)

[Anonymous No.8284641]

>>8284630
that's incorrect though. The question would have had to read (6 / 2)(1+2) in order for you to separate the 2 from (1+2). The correct reading would give you

6 / 2(1+2) which = 1

[Anonymous No.8284643]

>>8284606
not if you read the thread backwards

[math]2\over{2(1+2)}[/math][math]=[/math][math] 6\over2(3)[/math][math]=[/math][math]6\over6[/math][math]=1[/math]

Try it without the multiplication sign like how OP has it written in their actual question.

It automatically adds the multiplication because thats the function of a coefficient next to a parenthesis.

[eqn]
\begin{aligned}
6÷2(1+2) &= 6÷2(3) \\
&= 6 \cdot \frac{1}{2} (3) \\
&= 3(3) \\
&= 9
\end{aligned}
[/eqn]
