Farhad Ghassemi Tari was born in Tehran, Iran. He currently resides in Oxnard, California.

The author completed his Ph. D. program in Operations Research (applied mathematical programming) and graduated from Texas A&M University in 1980. Right after his graduation, he started teaching at Sharif University of Technology for thirty-six years, where he retired as an associate professor. During this time, he conducted research projects and taught several undergraduate and graduate courses, mostly in mathematical programming such as Linear Programming, Integer and Dynamic Programming, Nonlinear Programming, Sequencing and Scheduling, and Quantitative Method in Managerial Decision Making. Tari has published more than eighty papers in scientific journals and has held conference proceedings from the research results. His hobbies include reading books and listening to classical music. He also likes cooking.

Mathematics I and its complement volume, Intermediate Mathematics II systematically describe concepts and tools that are crucial to every college student who are willing to attain solid base for more advance mathematical topics. They aim to give the reader a comprehensive view of mathematics, its use, and its role in computation. These two books cooperatively may be different than other mathematics textbooks.

Every chapter starts with a romantic poem. Researchers have discovered that contemplating poetic imagery and the multiple layers of meanings in poems activates specific areas of the brain that help us to interpret our everyday reality. In these books, every topic is assisted by several examples. After presentation of concepts and tools, each chapter is proceeded with different real-life applications of the topics. Finally, each chapter concludes with 60 multiple-choice questions to attract deeper learning and understanding of the topics studied.
