Nobody likes the symbol. They prefer the
symbol or inequalities. However, this symbol is needed when working with Fibonacci numbers. For example the approximation:
, where F stands for Fibonacci number.
But there is an exact formula for Fibonacci numbers that have no
symbol. Fib(n) = https://latex.artofproblemsolving.com/8/6/d/86d486c560727727342090b432e23ba85ac098b1.png
