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.
Theorem:Binet's Formula:
