This book focuses on primary school mathematics for students, whether children or adults. It is assumed that no calculators are used, to encourage mental arithmetic. A parallel project at Wikiversity is underway to provide teaching tools to parents and educators, whether in traditional or home-schooling environments, at Primary School Mathematics.
