Starter code is available in lib/calc.rb. A pull request is not required, but it is necessary if you want a code review.

You may wish to refer to FAQs related to forking, cloning.

In lib/calc.rb, create a Calculator class with an initialize method that takes a starting number. You should then create calculation methods for each of the following operations that take a second number to perform a calculation on:

• Addition
• Subtraction
• Multiplication
• Division

In addition, there should be an equals method and a clear method. equals should return the current calculated value. For example:

calculator = Calculator.new(5)
calculator.equals # 5
calculator.add(3)
calculator.equals # 8

clear should reset the current calculated value to 0. For example:

calculator = Calculator.new(5)
calculator.equals # 5
calculator.clear
calculator.equals # 0

You should be able to create a new instance of your Calculator class and chain a calculator method to it to receive the correct answer by running pry and executing require_relative 'lib/calc'.

Be aware of whether your methods are returning Float or Fixnum results.

• Create new instances of a Calculator class with an initialized value
• Access calculator methods from this class within pry by executing require_relative 'lib/calc'
• Return Floats vs Fixnums for true values

Research Ruby's self, specifically in regards to method chaining, and refactor your Calculator class to allow for multiple chained calculations. For example:

Calculator.new(5).add(3).multiply(2).subtract(1).divide(3).equals #=> 5
