Hi friends,
can anyone plz help me out in solving this problem.
The problem goes something like this.
Derive a formula to find the sum of the following series.

Are bright middle school students who successfully complete a traditional high school Algebra I course in 7th grade ready for a traditional high school geometry course in 8th grade? I would like to hear from those who teach in schools that offer Geometry to middle school students ...

As I consider this factoring idea using the square root ambiguity I
find it amazing some behavior displayed by two sci.math regulars who
stepped in with mathematics when they thought they could dismiss my
ideas, but quit posting math when I pushed back a bit, also, of course,

Hey guys need some help on this.
You may have heard the fable about the touroise and the hare.  Suppose that the tortoise and the hare are running a 5000m race.  The tortoise proceeds very slowly, never changing its speed.  The hare runs very quickly at the start.  The tortoise ...

In your opinion, what is the best number theory textbook available
out-there?
The book should be accessible to someone who never heard anything about
(university) number theory.

I tried posting this under a different topic area but only received 1 reply which was a bit above my level of understanding (thanks anyway). Please consider the following:

exam tomorrow, its probably late in getting a response, lets try.
just a simple question P(2X + 3Y < 30).
E(X) = 0, VAR(X) = 4, E(Y)=10, VAR(Y)=9.
ans:0.5

let 'a' be an irrational number.
consider the set {n*a|n is a natrual number}
prove that the set {x|x= n*a - [n*a]} is dense in [0 1].
note: [y]=gratest integer less than or equal to y.

Hi everyone, I wonder if there is a discipline in maths to express knowledge, i mean, to express knowledge by mathematics expressions...is it possible?
Regards and thanks

I first began to get a real grasp of the true situation when I was
arguing about my prime counting function, which is actually THE prime
counting function, and after yet another useless argument on sci.math
with some regulars, it occurred to me, they had to know.

is there a general way to prove that a wff is satisfiable by every infinite domian but not by finite domain?

Now I am sitting here amazed as much as anything at yet another major
mathematical find.
S = (k_1*sqrt(x) + k_2*sqrt(y))*(k_3*sqrt(x) + k_4*sqrt(y))
is just one of those glorious kinds of brilliant ideas that just catch
