What was your inspiration when you co-authored this series?
I want the series to be the go-to resource for both students and teachers, something that they can rely on whenever they are in doubt. I also want it to be something that our children, our grandchildren, will still find valuable in many years to come. I asked myself this question, what are some of the features in the textbooks that I have, those that I used when I was a secondary school student, those that I used when I was a schoolteacher. I looked through them and I asked myself, what are the features that are meaningful to me, that are valuable to me, that I still want to have in my series. I pinpointed them down to three things.
