      Yes! WA shows the answer--and explains every step in English--to any math problem from any course at any level that we teach at the community college!
    • 5. Will it change the way we teach?
      Yes! Teach for concepts, application and deep understanding!

    • 13. “Mathematics is not a careful march down a well-cleared highway, but a journey into a strange wilderness, where the explorers often get lost.”
      -- W. S. Anglin, author of Mathematics: A Concise History and Philosophy, 1994
    • 14. The problem isn’t that computers “dumb down” math; we have “dumbed down” problems! – Conrad Wolfram

    • 15. “Math educators are spending 80% of their time teaching how to do calculations by hand. But math has been liberated from calculation. Instead we should be teaching how to ask the right questions, how to model the real world and how to verify our formulations.”
