We learn more by looking for the answer to a question and not finding it than we do from learning the answer itself.
Like a stool which needs three legs to be stable, mathematics education needs three components: good problems, with many of them being multi-step ones, a lot of technical skill, and then a broader view which contains the abstract nature of mathematics and proofs. One does not get all of these at once, but a good mathematics program has them as goals and makes incremental steps toward them at all levels.
Interpretation
What this quote means
Mathematics education requires a balance of problem-solving, technical skill, and abstract understanding.
In this quote, Richard Askey emphasizes the importance of a well-rounded mathematics education, comparing it to a stable stool that requires three legs. These components include engaging problems that encourage deeper thinking, the necessary technical skills to tackle complex tasks, and an appreciation of the abstract elements and proofs inherent in mathematics. He stresses that these elements should be developed progressively through a structured program, ensuring that students build a strong foundation in math over time.

A child, from the time he can think, should think about all he sees, should suffer for all who cannot live with honesty, should work so that all men can be honest, and should be honest himself.
So many young decorators are trying to reinvent the wheel, and the results are sometimes very dubious. They're striving to do things that have never been done before. Quite often it is done without authority, without knowledge, and without a background in taste. They need to be educated about the past, and they need a richer vocabulary.
At a time when the average student is graduating from a four-year college $27,000 in debt, when hundreds of thousands of capable young people no longer see college as an option because of high costs and when the U.S. is falling further and further behind our economic competitors in terms of the percentage of young people graduating from college, no agreement should be passed which, over a period of years, makes a bad situation worse and will make college even less affordable than it is today.
