2. Week

In the second week I have learned about implication and  negation . I found negation quite easy, since it is exactly the opposite of the original statement. On the other hand, implication was a bit challenging for me. I had problems to recognize when an implication is false. So, I had to review the course notes once again and figured out the main concept. For example, when we say " If it is rainy, we will go to the museum " (p =>q) , the only way that your promise can be broken is if it is rainy (p is true) and you do not take your friend to museum (q is false). If it is not rainy (p is false) you have no obligation to go to the museum, the promise cannot be broken.




3.Week

In this week we have learned about conjunction, disconjunction and contrapositive. For instance, we realized that converse occurs when two parts of the statement switched around and contrapositive swaps the parts of the statement and negates both. I am not fully confident about the material of this week. My main problem is to find the link between the concepts and their mathematical equation. In order to understand the main concepts I have to carefully review the learning material.
