No matter how many times you multiply the number 9, the answer will add up to 9. That's interesting. (Unless you're a cicada)

only up to 10

9x11 = 99

But then you do it again, so 9+9 = 18 and 1+8 = 9.

9 x 37 = 333, 3+3+3 = 9
9 x 528 = 4752, 4+7+5+2 = 18, 1+8 = 9

etc

oh shhhhhhhhh you pony tailed pole !!

Im totally bamboozled by the eggheads spouting off about prime this, cicada that ... Im off back to the "fry up" thread, I am comfortable there.

[AndrewT]

Seems like there was a big queue of people wanting to post exactly how Kev was wrong.

[Colchester Kev]

Shhhhhhhhh the lot of ya, Im sulking.

only up to 10

9x11 = 99

level?

if not 8+8=18
1+8=9

I think this mathematical genius deserves more love though

Shhhhhhhhh the lot of ya, Im sulking for 17 years.

FYP

lol, kev, you're such a tool. if you're going to quote someone to try and make them look stupid only quote the stupid bit, not the whole post that puts it in context and makes it obv it's a mistype.

next time just quote the bit you put in bold

[Colchester Kev]

mistype ... pahhhh ... that old chestnut.

[AndrewT]

8+8=18

[Jon MW]

...
 8+8=18
...

DUCY?

[gatso]

wp andrew and jon, that's so much better, that makes me look stupid rather than fat fingered.

DUCY kev?

[MANTIS01]

Impressive, philosophical, and logical thinking in this thread right now. So can someone explain why my Mrs is in a mood?

[Laxie]

Did you leave your dirty socks on the floor?

Oh my goodness - a dicussion on Prime Numbers, & Perfect Numbers - you've no idea what you have started, I'm endlessly fascinated by both.

I have to go to work in an hour, so I'll spare you - for now, but.....

When I used to play Roulette a lot (yes, I know, the shame), I had a "system", lol.

My numbers were 7, 11, 13, 17, 19, 23, 29, & 31.

On the Football Pools (remember them?), my numbers were.....

3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, & 43.

Every number I look at, anywhere, anytime, I have an urge to ask myself "is that prime?".

And as to Perfect Numbers, well, that's another story.

Now, I'm off to figure out this 8 + 8 = 18 bit.

Poor old Spacefrog, reading this, must have gone cross-eyed. They don't do Maths in France. Bad Manners, yes, great Flushy rubdowns, yes, but not Maths.

One of the points Simon Singh was making in "FLT" was that nature, & science, are linked, much more so than most of us ever realised.

To which end, he told the story of the Cicada, which, as Red rightly deduced, & AndrewT explained perfectly, avoids predators breeding patterns by breeding every 17 years. How Nature managed to figure that, or evolve to it, is some astonishing miracle.

Mr Singh went on to make another jaw-dropping observation.

Rivers - or the length of them.

He speculated/reasoned this - which it took me years to figure out, & I'm still a bit wobbly about it.

On average, the length of any River is able to be calculated simply. Take the distance in a straight line from beginning, inland, to where it meets the sea. Multiply it by pye. (3.147 etc....?). And that gives you the actual river length.

Which is, of course, nonsense. Or is it?

He reasoned that the banks & "menderings" of a river are formed as a factor of how fast the river flows. (Think river estuaries - fast-flowing & straight, whereas upstream, slow-moving & meandery).

The speed of the river dictates it's bendyness. The "inner bank" cuts faster, as the water flows faster on the inner side, & eventually, if it flows fast enough, it becomes straight, via bank-erosion.

How is that even remotely connected to maths, or pye?

Search me, I can't grasp it. But he says if you measured all the world's major rivers by that method, the + or - % would be less than 5%.

Go figure.

I've mused over that for years. I know, I'm a sad soul.
