while we are waiting:

a(b+c) = (ab + bc)

(a/b)(c + d) = (ac/b + ad/b)

since we do NOT have (6/2) we use a(b+c)
6 ÷ 2(2+1) = 6 ÷ (2(2) + 2(1)) = 6 ÷ (4 + 2) = 1

The funny thing is you still can't figure out why you can't get the original equation right.

I am just figuring out what I did wrong with these high school algebra problems. Because I haven't done this math for so long, I obviously slipped up, I wouldn't again, because at least I am still learning what I just did wrong.

And like I said. I need someone to reteach me how to do number 3.

You can't do basic algebra, so if I threw a few of those, with an Integration sign in front of it, I assume you would be lost.
So, high school student, who can't do basic algebra and order of operations, calls software engineering grad a twerp, and, with some 'imaginary authority' says his answer is "correct". Now, would you like me to tell you where you went wrong, or do you really not give a shit, and will stick to your 9 no matter what?

I see what you are doing. And it is why I messed up correcting Duc at first. The equations on that sheet are not written correctly either.

6 ÷ 2n =

n=1/3

6 ÷ 2n =/=

6=2n

its so not wrong. But after doing the worksheet problems, I understand why we are so used to treating everything that comes after a ÷ (division symbol) as a denominator. It is not correct.

Are you still in high school? Take it to your teacher. I know it is fucked up but your teachers did this to you by miss writing the problems on your worksheet. It is ingrained in you.

The answer is 9, and always will be my friend.

Alright, there's a lot of self-proclaimed experts around these parts. Let's see how your logic holds up against some basic mathematics.

6÷2(1+2) = ?

I'll give two hints. This is NOT a trick question, and there is only 1 correct answer.

All tools used for computation are fair game.

Yea I have been out of school for a while too. You remember your high school algebra better than I do.

The reason I am doing it differently than I solved the algebra problems, is because I am solving this correctly.

you cannot treat everything that comes after a ÷ as a denominator of a fraction....

Luckily for me, in my schooling, my teachers never used a ÷ but just wrote out the fractions.

I didn't become aware that teachers were writing out a ÷ expecting their students to treat it as a fraction...

The answer is 9, always will be. I am sorry you cannot learn new things and are so deadset in your ways.

Re: Math: 6÷2(1+2) = ?
Not only did I graduate grade 12 with honors, but I have a bachelors in computer science.

The question is:
6÷2(1+2)=?

That, in a properly normalized and fully expanded form is:
6÷2*(1+2)=y

Now solve it:
2*(1+2)=6y
2*(3)=6y
2*3=6y
6=6y
6/6=y
1=y

Answer is 1.

Prove it by substituting the answer back into the question and resolving it:

6÷2*(1+2)=1

6÷2*(1+2)-1=0
6÷2*(3)-1=0
6÷6-1=0
6÷6-1=0
1-1=0
0=0

It balanced. The answer appears to be correct.

Quoting: Anonymous Coward 31557420

yeah, that's it.

Now solve:

6 ÷ 2n = ?
Quoting: Anonymous Coward 32057798

6/2n=?
6=?(2n) [Multiply both sides of equation by 2n]
1=?(2n)/6 [divide both sides of equation by 6]
1=?(2X3)/6 [here is where the raw logic comes it]
1=?(6/6)

1=?
n=3

Now, verifying we re enter the numbers into the original equation

6/2n =?
6/(2X3)=1
6/6=1

Have a nice day and suck my balls, asshole.

There is NO other correct answer to this question and the fact that it has unknowns on both sides of the equation DOES NOT preclude it's being solved using simple logic.

Re: Math: 6÷2(1+2) = ?
Look at any book. All fractions used as coefficients use
6n
2

or

(6/2)n

therefore, to distribute 6/2, you would NEED parentheses around it. Otherwise, you distribute the 2 into the parentheses, which is called "Eliminating parentheses by distribution". It is not performing multiplication operator, since it is a "property" of math, ie, equality, and you are REPLACING, not multiplying. This is where other people are confused. They think "distributive property" is bound to the order of operations as part of multiplication. It is not.
So,
What do we have?
2(2+1) is 2 quantities, or groups, of 2+1.
In English, "I have 2 bags, with 2 apples and 1 orange in each bag." ie, 6 pieces of fruit.
Therefore 2(2+1) = [(2+1) + (2+1)]

6 ÷ [(2+1) + (2+1)] = 1
Ans: 1

Back to 6 ÷ 2n = 3/n. n = 2+1.
Ans: 1 again.

Distribute:
6 ÷ 2(2+1) = 6 ÷ [2(2) + 2(1)]
6 ÷ 6 = 1

If I add the 2+1 first, i STILL have to distribute, using the Identity Law of a+0 = a
6 ÷ 2(2+1) =
6 ÷ 2(3) = Here, I still have parentheses with a coefficient, so I can still distribute like this:
6 ÷ 2(3 + 0) Here I used the identity law to make it clear
6 ÷ [2(3) + 2(0)]
6 ÷ 6 = 1

No matter what math laws, rules, axioms, or properties are used, you always get ONE if you apply the rules correctly, which is the great thing about math, there is only ONE correct answer for simple equations like this one.
