README.md

Pseudo code steps

1 - print "Welcome to the calculator"?

2 - Get first number from the user

3 - Get second number from the user

4 - Ask which operation the user wants to perform

5 - Show the results

calculator.rb

# Calculate based on user input
def calculate(number1, number2, operation)
	result = case operation
		when "-" then number1 - number2
		when "+" then number1 + number2
		when "*" then number1 * number2
		when "/" then number1 / number2
		else
			result = "not valid"
	end
	return result
end

interface.rb

require_relative "calculator.rb"

other_operation = "y"

until other_operation == "n"
	puts "This is a calculator. Input 2 numbers"


	puts "1) Insert the first number"
	number1 = gets.chomp.to_f

	puts "2) Insert the second number"
	number2 = gets.chomp.to_f

	# # Assert + - / *
	puts "3) What kind of operation? \nChoose one: + - / *"
	operation = gets.chomp # Getting input from the user



	# Showing what the user inputed
	result = calculate(number1, number2, operation)

	puts "Oh, the result is #{result}"

	puts "Want to do another one? Type (n/y)"
	other_operation = gets.chomp


	# You can use REGEX! We are expecting N OR Y (the PIPE | is for saying OR)
	
	#unless other_operation == "y" or other_operation == "n"
	# ANY LETTER BUT N OR Y we break
	unless other_operation =~ /^n|y$/ 
		puts "This is not an option"
		break
	end
