Quote by William H. McCallum

"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."

"Perseverance is the key to success."

"Don't give up on what you believe in."

"I've been through worse."

"You learn to live with the pain."
