Funny Numbers
In mathematics, "funny numbers" is a name given to certain types of sequences or sets of numbers that possess peculiar or amusing properties. For example, a "vampire number" is a natural number that is the product of two smaller numbers, and whose digits, when concatenated in a specific way, form the original number. One example of a vampire number is 1260, which can be formed by multiplying 21 and 60, and whose digits, when concatenated, form 1260.
Funny numbers have been studied for centuries, and some of them have important applications in mathematics and computer science. For example, Fermat numbers are used in number theory to study the properties of prime numbers. Fibonacci numbers are used in computer science to design efficient algorithms for sorting and searching.
In addition to their mathematical significance, funny numbers have also captured the attention of the general public due to their unusual and entertaining properties. They have been featured in popular books, articles, and even works of fiction. For example, the vampire number 1260 was featured in the novel "The Da Vinci Code" by Dan Brown.
