This Manual is the first of three self-contained Manuals (Elementary, Intermediate and Advanced) which are designed for adults with a basic understanding of mathematics to learn or teach the Vedic system. So teachers and students could use it to learn Vedic Mathematics, it could be used to teach a course on Vedic Mathematics. This Manual is suitable for all students and teachers.
The sixteen lessons of this course are based on a series of one week summer courses given at Oxford University by the author to Swedish mathematics teachers between 1990 and 1995. Those courses were quite intensive consisting of eighteen, one and a half hour, lessons.
All techniques are fully explained and proofs are given where appropriate, the relevant Sutras are indicated throughout (these are listed at the end of the Manual) and, for convenience, answers are given after each exercise. Crossreferences are given showing what alternative topics may be continued with at certain points.
It should also be noted that in the Vedic system a mental approach is preferred so we always encourage students to work mentally as long as it is comfortable. In the Cosmic Calculator Course pupils are given a short mental test at the start of most or all lessons, which makes a good start to the lesson, revises previous work and introduces some of the ideas needed in the current lesson. In the Cosmic Calculator course there are also many games that help to establish and promote confidence in using the Vedic system.
