There are many misconceptions in people's understanding of mathematics which ultimately give rise to errors. The authors have identified 24 of those most commonly found and of these, the first 8 are listed below. The others will follow as they become available. Each of the documents to which these titles are linked provides an explanation of how the misconception arises so easily, together with some exercises aimed at reinforcing the correction needed. It is hoped that a study of the reason, together with practice of the exercises, will help to eliminate these errors.
