Meeting with Ashutosh Mukhopadhyay

Calcutta University and tried to bring various teachers from different parts of India to establish Calcutta University as one of the best universities of India. Similarly, he tried to bring teachers to Mitra Institution (Branch). Sir Ashutosh heard about Keshab Chandra, and he took him to Mitra Institution, Bhabanipur as a mathematics teacher.[2]
Due to his way of teaching mathematics Keshab Chandra came very close to Sir Ashutosh . Dr. Shyamaprasad Mukhopadhay son of Sir Ashutosh became a very good friend of Keshab Chandra and requested him to join politics which Keshab Chandra declined.

Mathematics books

In 1909 Sir Ashutosh along with his teacher Shyamacharan Bose wrote a book titled "Arithmetic for Schools". After the death of Sir Ashutosh, his son Shyamaprasad Mukhopadhay took the initiative to revise that book and requested Keshab Chandra to help him. After an untiring effort of Keshab Chandra Nag along with a few mathematicians in 1937, a revised edition of the book was published in the name "Patiganith". Kabisekhar (কবিশেখর) Kalidas Roy was a colleague of Keshab Chandra Nag. There was a regular gathering of various stalwarts in the field of academics and literature like Sarath Chandra Chattopadhyay, Premendra Mitra etc. was held at Kabisekhar's House, Keshab Chandra was a regular to that gathering. One day Sarat Chandra Chattopadhyay requested Keshab Chandra to write a mathematics book. After a few days, the same request came from Kabisekhar. Keshab Chandra was very confused whether to write the book or not and ultimately decided to write it for the benefit of students. His first book was Nava Patiganit (নব পাটিগণিত) from U.N. Dhar & Sons. Within a short time, this book became very famous among the students of class five and six. In the year 1942 Matric Mathematics, one of the famous books of K.C. Nag was published by the publisher Calcutta Book House. After this, he wrote many more books for various classes from IV to XII. These books were published in Bengali, English, Hindi, Urdu, and Nepali language. His younger son Late Taraprasad Nag started his own publishing house named "Nag Book House". This publishing house has now been renamed as " Nag Publishing House" and is managed by his grandson Dr. Tridibesh Nag. Tridibesh did his B.E. in Electrical Engineering and M.E from Jadavpur University. After this, he took over the publication and took every measure to ensure that the mathematics books by the legendary "K.C.Nag" never lost its reputation. His sole motive was to see to it that the students are not deprived of the privilege of learning mathematics from K.C. Nag's maths books. K.C. Nag's books from class 4–12 are the books which the students aspiring to excel in every walk of life had depended on at some time or other for the past three generations. Tridibesh formed a board consisting of eminent professors, school teachers, examiners, and successful students in order to revise the book from time to time.[5]
