Mental Math

  • Buy and read this book by Arthur Benjamin and start practicing. If you just need some inspiration and you’d like to hear some cool stories and tricks listen to this interview with the author.
  • If you would rather learn with video tutorials instead of by using a book, you could also sign up for a free trial on “The Great Courses Plus” website, complete this video course (also by Arthur Benjamin) in less than 14 days and then cancel (or not) your subscription. Or if you prefer, here’s a much older free course by the same guy.
  • Here are some sample mental math disciplines from the Canadian Mind Sports Association.
  • I’ve recently started playing around and enjoying the Mimir Mental Math app for Iphone. Seems great so far, with plenty of fun options and great instructional material. I also bought those great looking Mathemagic apps, but I haven’t started using them yet.
  • If you struggle with more basic math, this game would be worth playing around with for a while. It’s fun and good for drilling simple multiplications, divisions, additions and subtractions.
  • I use to use this simple and fast-paced game (no installation required) to procrastinate when I was a student.
  • Another great (and shorter) free series of videos by another teacher is this playlist.
  • Can you quickly tell me what day of the week was October 23, 1743? Last year national mental math champion can calculate the correct answer to dozens of dates in just one minute! How? Here’s one not overly complicated way. And if you have a system for memorizing numbers, there’s also a much efficient method that takes longer to learn. Hopefully I’ll find the time to explain it here soon!
  • For more advanced and difficult problems, it’s really helpful to learn how to use the art of memory to memorize numbers.
