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."

"Never underestimate the power of a good laugh."

"Laughter is the best medicine."

"A good laugh is the best medicine."

"Laughter is contagious and wonderful."
