Robot Name

When robots come off the factory floor, they have no name.

The first time you boot them up, a random name is generated, such as RX837 or BC811.

In other words, if I say:

puts "Robot 1: "

Variables = a place to store values
Operator = + - * / % = Parameter = inputs for variables
Fix_num = an integer

	##Dependencies
	#If you want to require library c when you install it it requires library d;
	#Things you are depending on depend on other things;

	##PACKAGE MANAGER SOLVES ALL OF THIS!
	gem install package name #Will work out where to store it on your system, it will work out all the dependencies and go and download them;
	#Some gems are very complicated such as ImageMagick, it depends on software that is written on your computer and not in ruby;

	require 'sinatra' #only works if we have installed sinatra on our machine;

	print "enter loan amount: "
	loan = gets.chomp.to_i
	print "Enter length of time in months: "
	time = gets.chomp.to_i
	print "Enter interest rate: "
	rate = gets.chomp.to_f/100

	i = (1+rate/12)**(12/12)-1
	annuity = (1-(1/(1+i))**time)/i
