I just want to know a few interesting facts, or fascinating things about mathematics e.g. the golden ratio in nature, or clever things about pi, how imaginary numbers are used... whatever!
Im quite good at maths, and its always been my passion, but I dont do A level or anything yet (and Im only a teenager) so give me something interesting yet understandable (ie no huge formulae!!!)
Please feel free to tell me anything you find is interesting, and the reasons I want to know this is a) it is fun b) it gives me something clever to talk about!!!.
Thank you all!

When you divide 1 by certain prime numbers, you get a repeating decimal. What's fascinating about these is that the length of the repeating string of digits is always 1 less than the number and that you can form 2/x, 3/x, 4/x, etc. using the EXACT same string of digits, just starting at a different digit and going in a circle.
Here's an example.
1/7 = .142857142857...
2/7 = .285714285714...
3/7 = .428571428571...
4/7 = .571428571428...
5/7 = .714285714285...
6/7 = .857142857142...
This also works for 1/17, 1/19, 1/23, 1/29, 1/47, 1/59 and 1/61.
Very cool.
As a kid - long ago before calculators - I discovered this myself one day and I know got as far as 61 in the excitement.
As a bonus, I've attached another link to a page which talks about fibonacci numbers and the golden ratio in nature.

I always find it fascinating to know that there problems
which are so simple to state, yet almost impossible to
prove.
Here are 2 examples:
1). The Collatz conjecture, or 3x+1 problem.
Look this one up and have fun with it!
2). The 0-1 squares problem.
Let n be a whole number satisfying
a). n is a square
b). the only digits of n are 0 and 1.
Must n be a power of 10?
It certainly seems true and we have numerical
verification for n < 10^32, but no one can prove it!

How much 'math' have you had? if you've had math up through Geometry and haven't yet seen it for the 'game' that it really is, then maybe you'd be better off getting into a subject that didn't demand a lot of math. Not being a 'math geek' doesn't make you a bad person ☺ Doug

hey, did you know that trisecting an angle is so hard it took 2000 to even write a proof that it's imposible? you probably knew that.
if you're interested in math you should get a book called ''archimedes' revenge" it's really cool.

i am only 14 math is really complicated so this might be easy to you factorize these:
(x exponent 2+10x+8)(35-8x+7y)-(10-23y+8x)

There are some sites about recreational mathematics, prime numbers, ans lots of links; I hope to give you some that you don't know yet. Please see the sources below.

read www.xkcd.com
He'll give you some good stuff to research and learn about. You just have to sort through the non-math ones

look up the Koch Snowflake. It has a funny name and it looks cool.
