Math Logs 04 Subtraction Mostly for Years/Grade 10, 11 and 12 Academic Courses Logarithms

This video was one of my early attempts to create one of these videos with my wonderful friend Cooper who inspired me to start.

So many people struggle with Logarithms (Logs). This shows some simple ways of thinking that I use to help people understand and use logs. In Australia these are taught in the 10A course and the academic courses in year 11 and 12 – Methods and Specialist / NSW Advanced and Extension.

After 40 years of enjoyable and rewarding teaching, I still love and continue to teach. It still amazes me how I continue to still think of better ways of teaching mathematical concepts and I also continue to discover methods of explaining things that help students 'better' understand and become more successful at remembering the concepts.

A word of warning from what I have repeatedly seen over the years - most of my videos are placed in a logical or reasonably sequential order and if you watch the first or second video in a playlist and feel comfortable with the concepts, please go to the last video in the playlist to check if you really are okay. Each video in a playlist usually becomes progressively more complex and the 'latter' or 'last' video will often contain common assessment questions where students are known to make errors.

I also often include some revision / consolidation / mixture videos in the playlist which I know are crucial to assist with student success in assessments.

I hope that you find this very helpful and a blessing in your studies.
