Build strong mathematical thinking from the ground up
Learn arithmetic by understanding its ideas and reasoning, not just memorizing rules. This edition adapts Hassler’s classic text for use in schools and private study, guiding teachers and learners toward clear, logical understanding.
This book emphasizes reasoning as the core of arithmetic. It shows how to connect simple ideas to more advanced topics, helping students grasp why rules work. It also seeks to make math useful in everyday life and in higher science, without sacrificing thorough, step‑by‑step explanations.
- Clear introduction to quantity and numeration, with a focus on how numbers relate to each other
- Foundations of proportional thinking, both arithmetic and geometric, with guided demonstrations
- Step‑by‑step reasoning that builds from elementary ideas toward general principles
- Practical scaffolding for teachers and independent learners, including examples and structured exercises
Ideal for readers who want arithmetic that teaches how to think, not just what to do. Suitable for classroom use or private study, and aligned with a method that values understanding, accuracy, and logical proof.
