Just like how you can't build a great building on a weak foundation, in order to nurture the great minds of the future, a better grasp on fundamentals is needed. Fundamentals of Basic Mathematical Tools (Class I-VIII) provides students with all the resources required to build a better grasp on mathematics. This booklet includes a detailed explanation of the basic concepts of mathematics such as multiplication/addition of signs, solving signed ratios, moving variables across the equal to sign in equations, discussion on roman numerals, conversion between units, solving for trigonometric ratios and many other areas which children find troublesome. Mathematics is perceived to be tough by kids but all they need is a better understanding of the basic concepts involved in the subject. The main objective of this book is to encourage students to pursue mathematics in higher education by helping them understand their fundamentals properly.
