Fibonacci Sequence

If you ever looked at the seeds of a sunflower you will notice that they will follow a pattern that spirals out.

If you count it, the seeds would spiral out this way:

1,1,2,3,5,8,13,21,34,55,89,...

This is the Fibonacci Sequence. To find next value just add the two preceding values, e.g.

1+1=2
1+2=3
2+3=5
.
.
.
FOREVER!

This pattern is all over in nature: in sunflowers and and in pinapples to name a few.

The Return of Pi-Day 2007

Pi Day is thought of being on March 14 every year, but do remember 22/7 is the closest fraction approximation of pi. In European style dates are written day/month as opposed to American style which is month/day soooo.....

22/7 would translate to (in European style).....

Pi day Returns!

Finally......A NEW POST!

Many of you have been wondering if I was going to post anymore (hopefully). Recently, I have had restricted acess to the computer due to many physical changes to my house but its now over so I hope to continue posting regularrly.

Here's a formula I found out by MYSELF (no books, websites, etc.)

If n is any positive number then:

2n+1= (n+1)^2 - n

Simpsons is Educational!?!?

When my parents think of the Simpsons, they think of yellow people who tell dirty jokes. But beneath all the political jokes and grossness, is mathematics. Yes you heard right, mathematics.

Trick of the 11s

Try to do these math problems quick.

1x11=
2x11=
3x11=
12x11=
13x11=
25x11=
32x11=
99x11=




Those last few got pretty hard unless if you know the trick of the 11s.

Example: 12 (I will only show the answer in the example.)
x11 (You can only do this with 2 digit numbers)

1. Drop down the 1s digit in the non-11 number, this is the ones digit in the answer. 2
2. Add the two digits together in the non-11 number to get the tens digit. 32
3. Drop down the tens digit to get the digit in the hunderds place. 132

Easy as that!

A few exceptions:

If in step two, the numbers add up to be more then ten, then only use the ones digit and add one to the tens digit in step three.

~Sorry for the bad tutorial. Just type "Multiplying by 11" into google.

Pi- Easy as 3.14159265...

How I wish I could recollect pi easily today!

Well here is a way to recollect pi easily today:

Count the number of letters in each word in the first statement and that number corresponds to a digit in pi.

How-3
I-1
Wish-4
I-1
Could-5
.
.
.
You should get 3.1459265 after finishing the phrase.


This phrase is called a PIEM. Another piem is:

"The point I said a blind Bulgarian in France would know."

Notice that point is in red. This is so becuase it actually represents the decimal point and should not be counted as a digit.

Have fun making your own piems and post them in a comment. Every once in a while I will post a piem.
