Deploying Finstagram to Heroku

These instructions will help you deploy your Finstagram app to Heroku (a web hosting service), so that the entire internet will be able to see and interact with your application! Before we get to deployment though, we need to make sure a couple of our files are setup properly.

Pre-Deployment: Edit Your Gemfile

Ensure your Gemfile file contains the following code (should match exactly).

source "https://rubygems.org"

gem 'rake'
gem 'activesupport'

Calculator Challenge

You have been tasked with creating a program that runs in the command line (bash). The program should ask for 2 numbers, a mathematical operator, and then execute the operation on the two numbers.

How It Works

• Can be run using bash (i.e. ruby yourfile.rb)
• Asks the user to input a number (i.e. 10)
• Asks the user to input another number (i.e. 5)
• Asks the user to input a mathematical operator (i.e. +)
• Outputs the the result of the computation (i.e. 15.0)
