Mathsy patterns

[JK Ferret]

Interesting patterns with numbers (duh)


ADDITION OF ODD

1 = 1 = 1^2 (^2 means squared)
1+3 = 4 = 2^2
1+3+5 = 9 = 3^2
and so on

ADDITION OF EVEN

2 = 2 = 1x2
2+4 = 6 = 2x3
2+4+6 = 12 = 3x4
and so on

TRIANGLE

1x8 +1 = 9
12x8 +2 = 98
123x8 +3 = 987
and so on

ALL THE ONES

1^2 = 1
11^2 = 121
111^2 = 12321
1111^2 = 1234321
and so on

ALL THE FIVES

5x2 +1 = 11
55x2 +1 = 111
555x2 + 1 = 1111
and so on

MAGIC SQUARE 9

2 7 6
9 5 1
4 3 8

Each row/column/diagonal sum is 15, AND

square each number, then sum of top = sum of bottom, and sum of left = sum of right


Just sum (haha) wierd and wonderful things that i thought was quite cool.

did Tom Cruise and Dustin Hoffman make a movie about you?


and you say i make you nervous!!!!

Go to uni and study some maths patterns, then you'll realise what's interesting. It makes me think the universe will eventually implode.

Hmm?? Which movie is this? and where did i say that?

[Dareos]

Rainman - the numbers thing


and my apologies on the nervous thing, it was 99flake that said i scared him, memory lapse on my part.

BOO!


scared yet?

Doing various moduli on Pascal's triangles makes pretty patterns (i.e. mod 2, mod 3, mod 4... on every number in the triangle, and colour the zeroes in one colour, the ones in another colour, the threes in another, and so forth)

I knd of like the Fibonacci series and the derivation of the Golden Ratio from it.

My daughter did a project on that when she was 13 - 14 and it's kind of amazing how often the golden ratio occurs in nature. Plants do it, molluscs do it, bees do it, spiders do it.

I bet I could find an example in the office now.

Maths is beautiful.

Sadly the stuff I used to do was chaotic, which isn't quite as pretty.

The equivocation of a binary erase channel, now that's interestizzzzz.
