"There is enough in the world for everyone's need, but not for everyone's greed."
"There is enough in the world for everyone's need, but not for everyone's greed."
"Mathematics is not about numbers, equations, computations, or algorithms: it is about understanding."
"The best way to understand something is to try to explain it to someone else."
"A good teacher is like a candle - it consumes itself to light the way for others."
"In mathematics, you don't understand things. You just get used to them."
