    Could you show your file/folder structure?
    And the classpath you are using when you compile the program.
    The classpath should point to the folder containing the folder that starts the package, in your case the Algebra folder should be in the folder at the end of the classpath.

    What is the value of the classpath when you compile the program?
    The full path consisting of the classpath concatenated with the package path should point to the class file.
    C:/test/java/Algebra/Functions/<function classes>
    classpath = C:/test/java
    package = Algebra/Functions
