কম্বিনেটরিকসে হাতেখড়ি - ১ম খণ্ড(পেপারব্যাক)

Good

Everyone participanting in Math Olympiad should read this book.

বইটি চমৎকার ৷ অনেক কিছু শেখার আছে ৷

Really great book written with great care. Seems like they really worked very well. Pages are bit yellow and good for the eyes. The quality of pages are amazing and thick. I would suggest everyone to buy this and understand the items of combinatorics.
