Crystal Clear Mathematics has been created after years of having parents and students recommend that I create a website to share my teaching and resources.
I grew up in Ballina, a small country town in NSW, Australia. During my high school years I managed to come first in the state of NSW in science (thank you, Bob Quinlivan) and second in mathematics and, after moving to Sydney came ‘dux’ of Normanhurst Boys High School.
Since leaving school I have undertaken twelve years of full time tertiary studies, taught mathematics to secondary school students (and even kindergarten to grade six) on-and-off since 1978, and currently tutor students in mathematics. I have also worked as a technician on a helicopter simulator, been assistant pastor of a couple of churches, run a small computer business, worked as a network administrator, and functioned as an office adminstrator and public relations officer for a financial firm.
My passion for mathematics was particularly fired upon my reading a book called “The Search for Pattern” by W W Sawyer when I was about fifteen. I wish to convey something of that passion through the material provided on this site.
Brilliant!!! This helps so much!!! So much easier than anything else I have found. This is now simple.
Thanks again for showing the simple way of doing this. I look forward to the next video!! Absolutely brilliant.
Once again, excellent! I’ve watched many others, that have not helped nearly as much as these. Thanks for making it so easy to understand. When things get complicated, it is easy to make a mistake, but your method of writing down the structure helps to prevent mistakes.
Thanks a million!!! I’ve watched many videos and read tutorials, but still could not get two in a row correct on Khan Academy. Your explanation was so clear and simple that it finally made sense to me and now I can get all of the problems correct!!! Thank you very much.
It all makes total sense now! Thanks very much for all the derivative videos!!! Very helpful.
