Mathematics is all about numbers. How we handle various types of number , how we perform arithmetic operations on numbers, and how can we discover unknown number. This chapter on playing with number deals with how can be find our number which satisfy a given arithmetic conditions. Playing with numbers chapter is covered best in

In our day to day life, we come across graphs and charts to analyze our data. Graph is data which is presented pictorially to get the required information easily. We see graph when we analyze performance of companies, or performance of welfare schemes or social measures, or analyze team performance. Introduction to Graph chapter is

Factorisation is related to multiple topics of mathematics, starting from day to day mathematics when we are calculating LCM and HCF , and with algebra when we are finding factors to determine like terms and unlike terms for solving expressions. Factorisation deal with getting the factors which divide the number completely. Factorisation chapter is covered

Direct and Inverse proportion chapter is part of ratio and proportion topic, where we have relation between two entities. Direct proportion relates to direct ratio, for example with same speed, distance travel will increase by time. Indirect proportion happen when with increase of value of one entity, second value decreases. For example, given a same

Exponents and power topic is related to algebra where we deal with different algebraic expressions and terms with different order. In order to solve the algebraic expressions, we may need to perform operations with respects to exponents and power like when multiplying or dividing two terms. Knowledge of how to handle exponents and power is
