Hey, I am studying for my first clep, in college mathematics. I hate math but always managed good grades. I am studying using instacert and the flashcards are using all these weird symbols and not explaining them. Like, R with a circle around it, the trademark symbol. Wtf does that mean in a math problem? Is there somewhere in the study guide that explains what these things are?
