This document is intended as a study help guide for students of general mathematics principles and processes. It's also a set of useful reminder sheets. I started it as tutoring notes for a Reconstructing Maths course student I was tutoring. She was studying to be a Primary school teacher what they now call Years 1 to 6 or Grades 1 to 6. Soon after I started tutoring her I started tutoring her son who was in high school, because he had some issues as well. I've not covered everything that's taught in high school, just the few I tutored them on. 8,000 words
