fine but it is actually relevant. You wouldn't be arguing your points the way you are otherwise ...



Maybe we should have a 'level of education' box to fill out on ATS. then we could see what level of education the person we're arguing with has on the off chance we could be wrong.

I would fill it out the same as I always fill those out...

"...Still repeating yr 8."

Is this really still going... the answer is 1... just drop it... the idiots saying 9 are idiots...

DISTRIBUTIVE RULE.... so many people are saying 2(2+1) ..... that the 2 doesn't need to be distributed after doing whats inside the parenthesis???.... well you're wrong, just because you simplified whats in the parenthesis they do not magically disappear.... and you can still distribute the 2 before hand and get the same answer....

6/2(2+1)

6/(2*2 + 1*2)

6/(4+2)

6/(6)

1

please stop confusing the young lad who originally asked the question...

Ok ill bite.

The way you have it written it is obvious you want it interpreted as

15*y
-------
5*y

Which simplifies to 3.

Your given equation however, simplified linearly = 15*y÷5*y
this simplifies to 3*y*y >> 3yy

When writing 15y ÷ 5y it is commonly assumed that 5y is the denominator, even though it technically needs parentheses. This logic should NOT be applied to the OP's question

6÷2(2+1)

In this case the answer is 3(3) = 9


If you got the answer 9, you should have answered 3yy for 15y ÷ 5y and not 3.

Compare 6÷2(2+1) = 6÷2*(2+1) and 15y ÷ 5y = 15*y÷5*y

It is operable... it just has more than one set of divisible subsets. I may have complicated it but what would happen when there is more than one divisible subset in an equation?


actually, it is not operable as written 2*4(3/4*2(14+2))5+6/(34/8.5)/2=?
if you follow to the second parenthesis, the next integer is "5" with no 'order' preceding or following the parenthesis ... just because the ( )5 is printed doesn't mean it gives any direction. when you close the parenthesis, that indicates a direction of procession. following that needs to be some form of 'order'.

to answer your question again, work from the inside out ... ex of your example: 2*4(3/4*2(14+2)) (can only go this far based on the example written) ... distributes to 2x4(3/4[(14+2)+(14+2)] and on down the line or 2x4(3/4(32) ... 2x4(3/128) ... 2x4(.0234) ... 2x(.0937) ... or .1874 for the value of the properly written side of your equation/expression.

IF the continued subset read something like (14+2))-5+6/(34/8.5)/2 ... again, work from the inside out ... value for left side ".1874" subtracted from the value of the right side. is this any clearer?

Simplifying is just combining like terms... it is 3y. That is it. That is really simple algebra .

3y * 5y + 4B -2B

15y+2B simply....

the distributive rule is A (B + C) = AB + AC

therefore,

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

A = 6/2 --- NOT --- 2

Compare 6÷2(2+1) = 6÷2*(2+1) and 15y ÷ 5y = 15*y÷5*y Multiplication and division, left to right, same priortiy.

Let me pose to you this question. What is 15÷3*4÷2*7??

You keep making an error and putting 6/2 in brackets where there are none.

If A = 6/2 then it would be in brackets. But it is not so A = 2.

this should be

15 * (1/3) * 4 * (1/2) * 7 = 70

I agree with you.

15*y
------- = 3
5*y


15*y
-------*y = 3yy
5


Either way you interpret it you dont get 3y. y/y = 1; y*y = y^2

3y is wrong

Yes exactly, so the answer would be 70.


Same with the OPs problem

6÷2*(3) = 9

15÷3*4÷2*7 = 70

In this case, the question should be written as (6÷2)*(1+2) or 6(1+2)÷2, then we can have 6/2 as A

but for 6÷2(1+2) , we cannot use 6÷2 as A

Sure you can! "A" can be any damn thing you want!!!

A ( B + C) = AB + AC

WhoTF decided to put the extra bracket in, that isn't in the original sum, the sum is...

6/2(1+2)= .... there is only one set of brackets, and they relate to the 1+2 portion.

Can see why OP was confused
edit on 2-5-2011 by solargeddon because: (no reason given)

no extra brackets are added except when entering the equation in a Linear calculator (ie: google)

you MUST include the order to multiply the sum of the brackets BEFORE dividing, these are the rules.

Yes you can. 6÷2(1+2) is exactly equivalent to (6/2)(1+2) if the order of operations are followed correctly.

In order to get

6
------ you need an extra set of parentheses 6÷(2(1+2))
2(1+2)

You are adding those in on your own when you write it as this fraction. Thats bad math

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