Write two examples of propositions in English, p1 and p2.

p1. If I pay attention to class, therefore I'll take good grades on test next week.

p2. I like cheese.

Step-by-step explanation:

Propositions are statements that declare something from/for someone. It always states something. It may be classified as simple (p1) or combined (p2) depending on the presence or absence of logical connectors p1 (If ... therefore). A combined proposition is made up of two simple propositions.

We can and ought work with symbolic operators.

Let p1 be translated into symbolic language,

I pay attention to class = q

I'll take good grades on test next week r

q→r

p2 = I like cheese. We can just simply call it p2.
