Please create a rails app in any rails/ruby version. Don't spend more then 2 hours (really). Submit either by commit to github, bitbucket, or zipping up your git repo and emailing it to jwindholtz@everfi.com, daniel@everfi.com, and jsamuelson@everfi.com.
Create a rails app that has one root page that is a calculator.
It implements these operators (say +, -, /,*) on any number of integer arguments.
The page has only a text box and a submit button.
The requested operation and its result should be displayed below the text box after clicking the calculate button. Please avoid using a gem for the calculation portion of the assignment and craft your own calculator mechanism (hint eval is not your friend).
We don't care about UI/UX. Please write up any tests you think might be important.
