actually, this clarifies your ignorance for me, thanks.
only in an instruction manual will you see such nonsense ... in the adult/real world, it's written 15y/5y=x, solve for x.
which cycles right back to 2(1+2) = 6 which is then divided by A (or 6) resulting in the answer yet again of "1"

In my world the answer to the equation; 15y/5y= x would be

x = 3

You solve the equation 6/2(1+2) wrong because you don't read the equation properly.

You take 2 and multiply this with 1 + 2. But that is wrong, because that is not what the equation is saying.

The equation is saying: Divide 6 by 2 and then multiply it with the result of 1 + 2.

What do you get if you do it properly?

9 right?

ok so you say but i disagree
the correct printing of what you say would appear ... (6/2)(1+2) and wouldn't be written any other way or the rules could not be properly applied.
when the equation posted is performed properly, the answer is 1.

hence (6/2)(1+2) is it's own problem with an answer of 9
but 6 / 2(1+2) is a different problem with an answer of 1

I see that in addition to math you have a reading comprehension problem. I'm not getting paid to tutor here. Can or did you even read those rules? Do you know what they say and how to apply them to 6 / 2 (1 + 2)?

edit on 2-5-2011 by MegaMind because: (no reason given)

mathgoodies is useful if you attend elementary school but that's about it.

yeah its pretty basic hard to believe you don't get it.

edit on 2-5-2011 by MegaMind because: (no reason given)

yes i sure did and yes i sure do so here's your freebie for the day ...
this expression is not a stand alone division problem, no matter which rule you apply.
since you insist on using the 'fraction' concept then remember the numerator is 6, the denominator is 2(1+2) ... once you solve the denominator (hence 6), then you proceed to the division of the numerator, also 6 and dividing 6 by 6 will ALWAYS = 1

WRONG

The dominator is the result of 6/2. Not 2, because that is not what the equation is saying. It asking for the result of 6 divided by 2. That means you have to solve the present asked question. What is 6/2.

What is the dominator?

The dominator is 3.

Now what is 3* (1+2)

Every student learns “the” distributive law at an early age:

No fear dear, my patience for dealing with students such as yourself wore out many years ago ... i tutor those who WANT help, not force feed those who think they know better.

God, I said I wouldn't come back but the ignorance here is astounding!

A (B + C) = AB + AC, just as above in the link you provided!

you do realize that A, B and C can be any number and that equation will hold true. Any number!

A can be a fraction 6/2 , B can be 1 and C can be 2

thus,

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

how shocking!!!

PLEASE for the love of GOD and all that is true DO NOT tutor anyone!

only the truly unwilling will argue with the facts placed in front of them ...
if 3(x + 7) = 3(x) + 3(7) is RIGHT
then 2(1+2) can only equal 6 ... the rest is elementary my dear.

and no, A, B or C are not vacillating variables as it suits your argument ... 6/2 in this example is an order not a fraction, period. If contemplating a fraction, then everything after the / (division symbol) is denominator, this includes the 2(1+2) or 6 once solved ...
please, continue once you've had some food or something that moves some blood into your brain.

6/ 2(1+2) is not a different equation then 6/2(1+2)

You are going to have to change it a lot more than that to make it different.

But i see the issue you face if you space out the equation between 6/ and 2(1+2).

6
-- = 6 / 2 = 6 ÷ 2 = 3
2

then what is the result of this?

6 ÷ 2 (1 + 2) ÷ 9 = ?

edit: I'm still waiting for the answer.

i did not change the equation other than add a space to make it easier on my eyes.
the calculation is the same, the result is still 1 and the 'fraction' is EVERYTHING after the division symbol, not just the 2.
however, (6/2)(1+2) IS different, IS calculated differently and IS a different answer ... that equation equals 9 ~~ not the equation posted ~~ 6/2(1+2) which equals 1
again that'd be 6 divided by 6 which equals 1

He should get the result he is fighting so hard for when he solves 6/2(1+2)

But i guess he will surprise us with something different this time

NEVER said it was ... try reading again please.

however, these 2 are not the same as many are trying to imply
6/2(1+2) is NOT the same as (6/2)(1+2)
they are different, results are different and the process to calculate is different ... how ANYONE considers them the same is beyond any reasonable deduction available.

what is this, a test? if so, try presenting it correctly if you want it solved correctly.
as written, the answer is -- .11111111111 etc .. 1111111111

if you are asking about this ... (6/2)(1+2)/9 = ? you'd get a different result ... this answer is 1, not .11111111 -- again, it is in the presentation of the equation.

i'm busy and you're not a paying customer ... you want an answer, try exercising some patience.

as a matter of fact, time's up and i gotta go ... i'll check back in a few hours ... you got your answers but i doubt you'll acquiesce ... we'll see if progress is truly measured by effort or argument.
where it is likely we'll progress in an argument, it would please me much more if the progress were measured by effort, really, you should try it sometime.

reply to post by Honor93


so you believe the answer is 1/9?

what about every thing after the FIRST "/" being the denominator? That was what u said earlier.

6 / 2 (1 + 2) / 9 = ?

edit on 2-5-2011 by Honor93 because: add text

HA! Got you!

6 / 2 (1 + 2) / 9 = ?

the answer, by the way, is 1. Given your logic I expected you to say either 1/9 or 9 depending on how you ordered it. (hint: that's why rules matter)

While I'm at it what about these?

3 / 3 / 3 = ?

3 / 3 * 3 = ?

3 * 3 / 3 = ?

6 / 2 (1 + 2) (1 + 2) = ?

3 * 3 * 3 = ?

I think your just trolling and I've been punked!

You log off and star yourself with another account

excuse you but "spacing" doesn't alter ANY calculations in algebra or linear problem solving.
reaching for straws i see.

these are the 2 equations being discussed
posted: 6/2(1+2)=?
argued: (6/2)(1+2)=?

contrary to popular opinion, they are not interchangeable.
they are not equivalent and they are not calculated similarly. any other foolish assumptions?

please pay attention to what you are writing ... your thought pattern seems to be on the mark but your writing leaves much to be considered.

A does not equal 6/2
a = 6
b = 2 times the sum of c
c= (1+2)
which calculates to the answer 1, only.

you are simply wrong. WRONG!!!

A (B + C) = AB + AC

according to your substitution from above the eq yields.

6 (2 * (1+2) + (1+2)) This is just garbage.

the correct substitutions for the equation are

A = 6/2 (a fraction get over it)
B = 1
C = 2

6 / 2 (1 + 2)

This is my reply to you Honor93

Well of course its wrong to space out the equation like you did. because you changed it totally.

You can't take 6/2 and do as you did. You can't take what 6 is divided by and carry it over to (1+2) and create the equation 2(1+2)

How is that possible?

Explain to me how that is correct.

reply to post by knightseifer


will you answer these then?

6 ÷ 2 (1 + 2) ÷ 9 = ?

3 / 3 / 3 = ?

3 / 3 * 3 = ?

3 * 3 / 3 = ?

6 / 2 (1 + 2) (1 + 2) = ?

3 * 3 * 3 = ?

And did you see these rules?

Rule 1: First perform any calculations inside parentheses.
Rule 2: Next perform all multiplications and divisions, working from left to right.
Rule 3: Lastly, perform all additions and subtractions, working from left to right.

Also you joined today just to discuss this topic?

Its funny how he can't see what he did wrong?

Well, i think he does but he's pride is getting he best of him.

Wait just one second.

I posted in this thread 14 pages ago, how can there still be debate about the math here?

I won't say anything on this topic except PEMDAS....And this is quite epic.

Don't feed the trolls though my comrades.
