Going to go with 0 as the answer. the working out is based on thats the number i think it is and i worked it out that way ...

That's interesting, because as far as I can recall multiplication has the same priority as division. Been a while since I did any math stuff though.
I hope i got the quote right... :S
but, i was doubting there for a minute.
10 / 2 x 5 = ?
10 / 2 = 5. 5 x 5 = 25
or
2 x 5 = 10. 10 / 10 = 1
so it does matter ;)
It matters, but as far as I recall it has the same priority, which means that the division would have to be done first since it's more to the left.
I could be wrong though.
You are right. Division and multiplication have the same priority, and they are done from left to right. After all in the problem stated:
10 / 2 x 5 = ?
if you want to do 2x5 first it has to be written 10 / (2 x 5), and then it's another problem.
So you can do:
10/2 = 5 * 5 = 25
or
10*5 = 50 /2 = 25

It's simple be the first to reply with the correct answer to the following math problem.
((815659 / 3 x (13 x 13 x 13)) - (1.548785) x .007)=?
Show your work btw!
Since there are a [ rnd ]-tag, the closest we can get are: Here
So.. Show me the isk

Nope.

There they show that DM and AS are on the same level and thus simply gets done left to right.
so 10/2x5 is exactly the same as 10x5/2
10/2x5
=5x5
=25
10x5/2
=50/2
=25

Division does not need to come before multiplication if you know the correct way to handle it (a multiplication after a division with no parenthesis multiplies the dividend and not the divisor). As for the addition comming before the substraction, as far as I have been taught, is simply not true:
10-5+5 -} 10-5 = 5 +5 = 10
is correct and what's below is not
10-5+5 -} 5+5 = 10, 10-10 = 0
In fact operations in the same "level" can have it's order switched and still deal the same result:
10-5+5 = 5+10-5 = 5-5+10 = -5+5+10 = -5+10+5 = 10
10/2*5 = 10*5/2 = 5/2*10 = 5*10/2 = 1/2*5*10 = 1/2*10*5 = 25
Have fun

This is right as long you only stick to * / + -
But as long as a math is is set up like this:
X / 3* (13^3)
is the same as:
X
----------
3 * (13^3)
This since the "*" are to the ( )

Left <-----------> Right
There is a specific order in which to do certain things, but in some cases 2 or more operations have the same priority, in which case you go from left to right.
The reason for this to be discussed is that most ppl have calculated
ááárnd / 3 x (13 x 13 x 13)
as
ááárnd / (3 x (13 x 13 x 13))
which is wrong, it should be
ááá(rnd x (13 x 13 x 13)) / 3

why is it so hard?
a random number added,subtracted,multiplied,divided by anything oly equalls a random number so the answer will and always will be RND.
((RND / 3 x (13 x 13 x 13)) - (1.548785) x .007)=?
answer is RND.

You perform division operations first, it's as simple as that. There's no priority of symbol ordering, it's just that division is non-commutative and thus convention is just that you essentially treat division ops as bracketed. I've never, ever come across any rule about "left to right" or anything like that. Besides, if you just blindly process LtR you screw up 5 + 10 / 5, which is 7 not 3.
This, incidentally, is why if you're writing proper maths you express division with the dividend on top and the divisor underneath.

I don't think that the "random" number at the beginning of the equation is "random". I think that it is being generated by the "answer" which is being randomly generated by an algorithm.
I worked the problem into this form (x)=(3(f(y)+.010841495))/2197
where f(y) means "a function of y" and x is the changing number
I have made the following assumptions based on 100+ refreshes of the thread--the changing number in the original equation has limits of 0-999999, must be positive, and must be an integer (it could be rounded to an integer).
With those assumptions in mind, take the value of "y" to be the seed, and it will have limits of .000015 and 1365.5 (these are approximate as I do not know how many decimal places we are working with.
This leaves me with the impression that the generation algorithm f(y) is generating a number between the above limits. Now the true trick is to figure out just what that algorithm is based on.
I may not be right, but I feel it is a step in the right direction.
Just my 2 isk.

This, incidentally, is why if you're writing proper maths you express division with the dividend on top and the divisor underneath.
While the last thing you said is completely true, the one before is not so acurate. You don't blindy process LtR, you process LtR with the operators with the same priority.
Thus 5+10/5-5*5 should be done this way:
10/5, 5*5, 5+(2), (7)-(25) = -18
if you exchange the operators of the same level you keep the same order
5-10*5+5/5
10*5, 5/5, 5-(50), (-45)+(1) = -44
In fact the original poster could have left out all the parenthesis and the operation would have been the same as the one he descrived
898107 / 3 x 13 x 13 x 13 - 1.548785 x .007=?
or
898107 * 2197 / 3 - 0.01841495 = ?
or
(898107 * 2197 - 0,05524485) / 3 = ?
or ....

The answer is easy - but Im lazy to looking for it.
The answer is interval. What you need is to find definition of the rnd function. it will return random number from some interval (0..65525, -256..255,etc - I dont know. But Something like that. As I said I lazy to use google for it)
When you have the interval of the random numbers, it should be easy to calcute the interval of result.
ok - who is not lazy as me and wil recieve the 5 bil ISK? (and when you recieve it, dont forget to share some with me :-))

Uh, see my above posting about podding whoever taught you that multiplication binds more tightly than division. Regular math doesn't allow you to put parenthesis around that divison. *)
You're the Google generation, right?
Try [url=http://www.google.com/search?q=10/2*3]http://www.google.com/search?q=10/2*3[/url]. Google helpfully adds brackets to indicate the order of evaluation. And Google's always right, right?
Interestingly enough, potentiation *does* bind more tightly than divison, so 1 / 13 ^ 3 = 1 / (13 ^ 3). But that's potentiation. Multiplication has the same right of way as division.
Also, I'd like to point out that in your friendly picture you're trying to apply " *Y " to both sides of the equation.
Please apply it to all components of both side the same way. That means, you forgot to apply it to
-0.010841495 and you also applied it to the divisor only (under the ------), which is illegal: Has to be applied to the whole term:
( Y / 6591 ) * Y - 0.010841495 * Y
You could try to apply " /Y " to both sides, but tbh it won't help a lot.
Still, nice try and keep going, and I think any more bad math in this thread and I'm going to go to Amamake and shoot up someone.
*) Could still be valid in Brutor High, but what they do to math there is more of a Martial Art than a Science.

It's simple be the first to reply with the correct answer to the following math problem.
(([ rnd ] / 3 x (13 x 13 x 13)) - (1.548785) x .007)=?
Show your work btw!
[ rnd ] ranges from 0 to 999999
for [ rnd ] = 0
? = [(0/3)x(13x13x13)]-[(1.548785)x(0.007)]
? = [0]-[0,010841495] = -0,010841495
and for [ rnd ] = 999999
? = [(999999/3)x(13x13x13)]-[(1.548785)x(0.007)]
? = [732332601]-[0,010841495] = 732332600,989158505
Therefor ? = between -0,010841495 and 732332600,989158505
And since there are actually two variables (being [ rnd ] and ? ) and only one equation, this is not solvable.
Where both ? = between -0,010841495 and 732332600,989158505 and "this is not solvable" are correct answers.
