Week 5: Direct Proof, Indirect Proof, Proof by Contradiction

Hello Rod here,

This week we only had two lectures but we started learning about the content of a proof. Last week when we only learned about the structure of a proof which I got pretty comfortable with. This week in lecture we worked on some proofs. We proved direct proofs by proving the statement that was given to us. Usually using some algebra and manipulation. We also worked on indirect proofs which required us to take the contrapositive of the statement and prove that. Also when we wanted to disprove a statement we learned that we should prove the negation of the statement in order to disprove the original. I still feel really weak in proving the content myself. Hopefully i'm just going to follow the lectures, work on the assignment an do some sample proofs on my own so I feel comfortable writing complete proofs.
One more thing I also learned this week is grounding. It was brought up in lecture but we didn't really talk about it so i had to go find it out myself. Yep that was it for this short week.
