College Algebra, Third Edition review: 5 stars (An Introduction to the Theory of Numbers) - I had the chance to go through the above book and I must say that I found it very useful. I very much liked the modern approach to the theory of numbers and the use of the historical aspect.I am in Ghana teaching at the University of Education Wnneba. How can a get some copies for the Departmental Library?I can not give much detail review now until a get a copy of the book.
