The impact of vague belief 'Mathematics is hard subject' embedded among almost all parents, guardians and persons inside or outside of the educational ambience in the civil society leads a student to be afraid of the subject. This book is a humble effort to find out some remedials by which our dear pupils can be able to overcome the age old so called "Fear" myth in learning Mathematics. Besides this, the author is also presenting some "Technical Know How" in solving mathematical problems practically, which he faces as a secondary level school teacher day in and day out. There are easy going, genial and tolerant discussions in this book about the problems on major concept: H.C.F. and L.C.M. of Algebraic Expressions which have been arising in the syllabi of W.B.B.S.E. as well as C.I.S.C.E. This book will be useful for the learners of schools and their teachers, B.Ed. students and teachers, curriculum developers, researchers of various levels and those who are interested in learningmathematics.
