PRACTICAL MATHEMATICS Stage I by FRANK CASTLE - Hardback - 1955

A vintage 1955 good hardcover copy of PRACTICAL MATHEMATICS Stage I by FRANK CASTLE

"To perform his work intelligently, an artizan must have a knowledge of Elementary Mathematics. When he comes to appreciate this fact for himself the workman generally finds that even the arithmetic he learnt at school has left him, and that he remembers little more than four simple rules and the multiplication table. Teachers soon discover that though anxious to learn, a student of this kind does not wish to lose contact with the practical requirements of the workshop,-he is impatient of "pure" mathematics, so the question arises how to teach him mathematics enough, by dealing with the calculations themselves which he is actually called upon to make at his work."
