New Practical Arithmetic, In which the Science and Its Applications are Simplified by Induction (English Edition) by Benjamin Greenleaf is a classic instructional text designed to make arithmetic clear, usable, and firmly grounded in understanding rather than rote memorization. Written with a practical purpose, it guides learners step by step through fundamental numerical principles and the everyday applications that give them meaning.
Greenleaf’s inductive approach emphasizes learning from examples and gradually building toward general rules, helping students develop confidence with computation while also grasping the “why” behind standard methods. The book presents arithmetic as both a science and a tool, connecting core operations and reasoning skills to real-world problems in business, measurement, and common transactions.
Whether you are a student seeking a structured, traditional course in arithmetic, a teacher looking for a historically influential classroom resource, or a reader interested in the development of mathematics education, this edition offers a clear window into a time-tested way of teaching practical mathematics—careful, methodical, and focused on lasting skill.
