I really love hearing answers to questions like these; great idea!
What is good?
In my opinion, "good" is word used to embody an idea held by a group or a person. I think that this idea depends greatly on the party to which the idea belongs. For example, in most Christian communities people share the belief that God is "good" in that He is all-loving. A different Christian group that came to protest at my university in 2010 believes that God hates certain people and does "good" by killing them. Generally, it seems that "good" has a connection with the idea of morality.

What is 2 + 2?
"2 + 2" is a series of symbols used to represent an idea (much like words). "2" is commonly interpreted as the number two. The concept of numbers is something we created to make an organized system for manipulating patterns we see in the world. In mathematics, "+" denotes addition. Were we to add the integer two and the integer two in decimal system, we would arrive with the integer four. However, a variety of answers can be achieved depending on the system and whether or not fractions are used.
What do you know?
I must quote Plato here: "And how will you inquire, Socrates, into that which you do not know? What will you put forth as the subject of inquiry? And if you find what you want, how will you ever know that this is the thing which you did not know?" That is from Meno 80d.
