Excerpt from Key to New Practical Algebra, for Teachers And yet it must be admitted that a majority of teachers desire a key. This demand comes not only from young and inexperienced teachers, but from those whose char acter and scholarship are above suspicion. They desire it, not because of their inability to solve the problems, nor because they shrink from labor. Their object is to save time, which they may devote to other branches of study. A well constructed Key will often disclose in a single minute the error in a pupil's work, which might consume half an hour of the teacher's time, if he were obliged to wade through a long operation.
