- Learn about numbers in Ruby.
Research and then write answers to the following questions in lib/numbers.md.
- What are the different kinds of numbers in Ruby?
- What are some common operations and comparisons you would perform on numbers?
- What is the difference between the
+operation on a number versus on a String? - If you have a String
"20"and want to perform a mathematical operation (like division or multiplication) on it, will it work? If yes, why? If not, how would you make it work? - What is the purpose of the
timesoperation? Is that the same as*?
Remember two things:
- You don't need to submit any code to us for this assignment. Just provide in-your-own-words answers for the questions above.
- We're not looking for any kind of advanced writing skills nor any kind of length. Just be clear and thoughtful about what you write--organize it however it makes sense for you.
As always, one resource is Google. Some of the questions above can by entered verbatim into a Google search, and for others that won't be as effective. Either way, expect to read (or watch videos) about more than just the simple answer to each question. Often a question's answer--even one that seems short or simple--doesn't really make sense until after you've read the paragraphs before and after it.
