And thanks for the explanation about your learning preference. I would say that visual learners tend to have an advantage during Prep Work, and auditory learnings have a _significant_ advantage during class itself. Just saying–something to look forward to :)\r\n\r\nYour questions:\r\n\r\n1. `<<` is an \"alias\" for `push`. So with an array, doing `<<` is the same as doing `.push`.\r\n2. Arguments and parameters are essentially synonymous. (They're not, actually. But they _are_ unless one's being pedantic.)\r\n3. In Ruby, the last line of a method is assumed to be the return value. So `b` is the same as `return b` if it's the last line of the method. This is known as an \"implicit return\"–as opposed to \"explicit return\" which would include the `return` keyword."}}
