I have just started Discrete Math this week. I am watching Discrete Mathematics video via YouTube and still a little hazy on some of my assignment questions. I am reading the text in the chapter prior to starting my assignments and while gaining a little bit of knowledge; am still lost on some of these questions.
"Rewrite each of the following statments so that it is clear that each is an implication." ***I am not sure if my thinking is accurate on this question.***
(b) The product of rational numbers is rational. (My answer: "The product of irrational numbers is not rational.")
"Write down the converse and the contrapositive of each of the following implications."
(d) If n is an odd integer, then n2 + n - 2 is an even integer. (I did not write down an answer on this one. I have no idea what is being requested.)
Thank you for any assistance. I apologize if this is basic questions; I am a little lost in this class.
