Moment of Clarity

Before this trimester, I heard about how confusing some of the work we would be doing would be, and they were right. when i first looked at adding, subtracting, multiplying and dividing functions, my brain didnt know what to do about them, partly because I was gone the day you explained them, but after reading through the notes on them they started to make more sense. i could see how to find the domains of those functions, both when alone or combined. and these notes that you gave us provided that moment of clarity for me.
