One of the most difficult parts about this unit was the introduction of floating$-$point variables and remembering the differences between integer variables and floating$-$point variables. The concept itself is easy to understand but it is also pretty easy to mix the two up if you are not paying enough attention to it$.$ I think within this unit, binary numbers were actually the easiest to understand, but who knows it is most likely going to get more difficult from here, but for now it was the easiest to understand. I don$$t really have any questions, it is mainly that I need to study and do more practice so that it gets easier to do$.$
