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."

"You can't expect to be happy if you're surrounded by mess."

"Health and happiness - these are true wealth"

"How can you live like this? It's like a pigsty!"

"You're going to get sick living like this."
