Ordinary Level Mathematics Key Facts was first published in 2008 as Rudiments of Ordinary Level Mathematics. It is a snappy and straight-to-the-point, ordinary-level mathematics book with many graded, solved examples and over one thousand, four hundred multiple-choice questions. The book covers almost every objective required in mathematics at the ordinary level (grades 8, 9, and 10).

The book also includes many new topics, such as logic, networks, and flow diagrams. The objectives, concepts, and skills are summarily presented and illustrated with examples, diagrams, or both where necessary. Each chapter begins with brief notes and ends up with a good number of multiple-choice questions. The answers to the multiple-choice questions have been voluntarily left out to ensure that students really work through the exercises and not memorize the answers. The book is highly recommended for final-year students and students in evening schools.
