The four works from this period which have come down to us are:

Liber quadratorum (1225)

Fibonacci's Mathematical Contributions

Roman Numerals
I = 1, V = 5, X = 10, L = 50, C = 100, D = 500 and M = 1000
For instance, 13 would be written as XIII or perhaps IIIX.
2003 would be MMIII or IIIMM. 99 would be LXXXXVIIII and 1998 is MDCCCCLXXXXVIII
For example, XI means 10+1=1 but IX means 1 less than 10 or 9. 8 is still written as VIII (not IIX)

Patterns in the Fibonacci Numbers & Cycles in the Fibonacci Numbers
Here are some patterns people have already noticed:
Pattern Number 1
0,1,1,2,3,5,8,13,21,34,55,...
Pattern Number 2
00, 01, 01, 02, 03, 05, 08, 13, ...
For the last three digits, the cycle length is 1,500
For the last four digits,the cycle length is 15,000
For the last five digits the cycle length is 150,000
and so on...

Fibonacci's Rabbits The original problem that Fibonacci investigated (in the year 1202) was
about how fast rabbits could breed in ideal circumstances.
. .

The number of pairs of rabbits in the field at the start of each month is
1, 1, 2, 3, 5, 8, 13, 21, 34, ...

What's the best angle to have between SEEDS in a seedhead?
The best angle must have NO gaps which waste space and evenly space the seeds aboutthe seed head.
Angle between successive seeds = 342.164°
Fraction of turn between seeds = 0.950
What is the Golden Section (or Phi)?(Also called The Divine Proportion)
Golden Section, in mathematics, a geometric proportion in which a line is divided so that the ratio of the length of the longer line segment to the length of the entire line is equal to the ratio of the length of the shorter line segment to the length of the longer line segment.

The Golden Section in Architecture The Parthenon and Greek Architecture
Even from the time of the Greeks, a rectangle whose sides are in the "golden proportion"
(1 : 1.618 which is the same as 0.618 : 1)
