Experience

My teaching experience goes back more than 50 years.  As a school student in what is now called Grade 9, I taught mathematics to Grade 11 students as well as to students in my own grade.  While a student at the University of the Witwatersrand, I ran mathematics classes for all grades from my home.  This was a free service to the community.  Throughout my professional career I have continued to teach mathematics privately.

Industries

After graduating in Applied Mathematics and Computer Science, I have had a successful international career as a mathematician and software developer in the following industries:

• Gold mining and metallurgy.
• Banking, insurance and finance.
• Telecommunications.

After retiring from the corporate world, I have also taught at schools and privately.
