Before the refactor
[ruby]
class Calculator
attr_accessor :number_one, :number_two
def initialize number_one, number_two
@number_one = number_one
@number_two = number_two
end
def calculate
if @number_one == 5 and @number_two == 8
puts "Are equal to 5 and 8: #{@number_one} and #{@number_two}"
else
puts "Are different to 5 and 8: #{@number_one} and #{@number_two}"
end
end
end
calculator = Calculator.new 5, 8
calculator.calculate
