About Kalid Azad

I enjoyed math until a poorly-taught class nearly destroyed that passion. A last-minute Aha! moment showed me math could make sense, even be enjoyable, when presented with:

  • A friendly, curious attitude
  • A mix of intuitive and technical understanding
  • A focus on lasting insight

I share explanations that helped, hoping they help you too. I’m thrilled that BetterExplained now reaches millions every year, and has appeared in blogs for the New York Times and Scientific American. Pets First Collegiate University of Kansas Jayhawks Dog Mesh Jersey, X-Large
