Math: 6÷2(1+2) = ?

Don't try something so hard for you, when can't even get the first one right. Come back to those when you are little older.

An you still get an F. Easy.

Where is your source, that you don't need parantheses. Still waiting?

So easy an equation that none of you will embarrass yourselves by answering it.

I gave you the source: Identity Law:

Solve a ÷ 1a ? or a / 1a = ?

And here is an algebra lesson that you so desperately need.

[link to cstl.syr.edu]

So you're argung that 2(1+2) is equal to (2x(1+2)) because of the identity law?

You can't dispute that 9 is the answer, because it is.

Identity Law proves a ÷ 1a = 1. This means a ÷ (1a) = 1, and not a squared
a ÷ 2a = 1/2
6 ÷ 2a = 3/a. Let a = (2+1)

The logic is not hard to understand, but I have never seen it written that way. It is not proper written math imo.

I see the idiots are out tonight. "it is 9, because it is". You are a retarded troll... troll on.
Here is what you DON'T know:
(6/2) must be in parentheses to multiply something also in ( ).
6 ÷ 2n = 3/n
(6/2) must be in ( ) to distribute. In this equation, is is not, so we distribute the 2.

Here is your lesson, once again. Go learn, or remain ignorant: [link to cstl.syr.edu]

Your opinion doesn't matter to math LAWS:

You are dead wrong.

6÷2(1+2)=
3(3)=
9

It's actually there in your link.
What a dumbass you are.

Another site called it the Redundance Law: 1A = A

Solve either of these questions, dumass:

12x² y ÷ 4x + (6x – x)²

{4 [2xz^4 (2c³v ÷ 2cv²)³ ÷ 2]} ÷ c^6x • v³ = 4z^4 = ??

I don't have to, you just lost in third grade math.

Yes, you can write it that way with variables. But not in a normal equation without variables, that is where I diagree.

Get a life >>>> [link to i1249.photobucket.com]


and a scientific calculator as well...


.

135 fucking pages??!! Any idiot that doesnt know correct answer is 1 should give up on life now. Pathetic morons

Dumb dumb dumb...



God you know absolutely nothing about math, let alone the equation at hand. You can't solve THIS equation, nor any of the other ones I gave you... you don't know the identity law, the distributive property, or what a variable is. Who failed grade 3 ????

you and you're casio are doing it wrong.

[link to www.wolframalpha.com]

The how is this wrong?

6÷2(1+2)=
3(3)=
9

The link gets screwed, but there you can find the mathematical answer.

NOT casio (who has sold thousand of this in the world till now), but all the others as well.

However, you can even send them a letter, they are hiring...



.

PEMDAS, Parenthesis, exponents, multiplication OR division left to right, Addition OR subtraction left to right.

6/2(1+2)
6/2(3)
3(3)
9

But, this was not taught to people this way before the seventies, because I know people in their 60s and 70's will disagree to the grave on how to do this.

6 / 2 (1+2)=

6 / 2 * 3 = 9

Answer is 9

Work out the bit in parenthesis first
Then work left to right

Next

I can't help it if they get it wrong.

Right, millions of people used this calculators since decades and nobody complains; Now we have a finnish guy that discover a nice site that should change the world.

Interesting...

It's 9. Always will be.

It's just basic math. You don't have to believe me if you don't want to.

I'll put this here:
