"My name is Anthony Tartaglia. It has now been ten years since I graduated from Aviation High found in Brisbane, Australia. During my last two years of high school, I had this idea of writing my own textbook because I didn't understand much from the supplied textbooks. Basic definitions and clarity of topics or equations for example were missing and such things would have really helped. Since I enjoyed math quite a lot, I was almost always willing to help explain my view of math concepts to others as I learnt them. So, from scratch I made this very textbook originally for Year 11 students but have made it helpful for before and beyond Year 11. I explain concepts and equations and many things which I hope will help your journey in math. I very much thank my Heavenly Father, my wife Carolyn Tartaglia and family who have supported me. I also thank all the teachers that have helped me learn math and other subjects, and I especially thank my Year 12 Math B teacher at the time (Mr. McGrath) for the talk we had about this idea. I hope my efforts will help you achieve so much more in life, mathematically and beyond."
