What is a Symbol?

A symbol is anything, really, that can stand in for something else.

pi is the symbol for the ratio of a circle’s circumference to its diameter, an irrational.Archimedes

phi is the symbol for the golden ratio, a + b / a = a / b, also an irrational. Michael Maestlin

In programming we use symbols to represent whatever we want them to represent, they’re called variables.

MY_SYMBOL = "Whatever I want it to represent".
