Fibonacci Day Cards

Fibonacci Day is celebrated on November 23rd to honor the Fibonacci sequence, a series of numbers discovered by Leonardo of Pisa (Fibonacci) in the 13th century. The sequence begins with 0 and 1, with each subsequent number being the sum of the two preceding ones. The date, 11/23, reflects the first four numbers of the sequence (1, 1, 2, 3). It is a fun day for math enthusiasts to explore patterns and the significance of the Fibonacci sequence in nature, art, and science.
