Fib is a term often used to describe a small or trivial lie. It typically refers to a falsehood that is not intended to cause significant harm or deception. People might tell a fib to avoid hurting someone's feelings or to make a situation more pleasant. In mathematics, Fibonacci numbers are a sequence where each number is the sum of the two preceding ones, often starting with 0 and 1. This sequence is closely related to the concept of Fibonacci spirals found in nature, such as in the arrangement of leaves or the pattern of seeds in a sunflower.
