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

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

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?

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...

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??

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

Simplifying is just combining like terms... it is 3y. That is it. That is really simple algebra .
3y * 5y + 4B -2B
15y+2B simply....

It matters not. The answer is 70 either way.

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

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 confusededit on 2-5-2011 by solargeddon because: (no reason given)

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