The text is an excellent exposition of the essentials of discrete mathematics. This book is a product of
long experience of teaching the subject in M.C.A. and B. Tech. courses in University of Calcutta and the
Institute of Engineering and Management for a number of years. The contents include propositional
calculus, number theory, permutations and combinations, probability theory, and graph theory. The
groups, rings, fields and integral domains have come up for discussion as natural habitats of the domain
of discrete mathematics. A sufficient amount of theory is included for those who enjoy the beauty of the
development of the subject and a wealth of applications as well for those who enjoy the power of
problem solving techniques. Hopefully, the students will benefit from the nice balance between the two.
Apart from this, the students will also enjoy the solved problems demonstrating various techniques.
An educationist and scholar Dr. Dipak Chatterjee started his career at St. Xavier’s College, Kolkata as a
Lecturer. Subsequently, he became Reader and finally retired from there as a Distinguished Professor

taught in Calcutta University, IGNOU, IISWBM, NSO University and many engineering colleges, and
management institutes. After retiring at sixty from St. Xavier’s College, he worked as the principal of the
Institute of Engineering & Management for almost eight years and then became the Vice Chancellor of
the S. S. University, a post he held for two years. He completed his Ph.D. from Indian Statistical Institute
and Calcutta University. The courses he taught include Ph.D., M.Phil, M.Tech, M.Sc., M.B.A., M.C.A,
M.Com, B.Tech, B.Sc, B.B.A., B.C.A., B.Com. Apart from many awards, he won the Mother Teresa Award
