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

Mensuration topic is related to practical aspect of geometry, where we analyze different geometrical objects and understand their measurements. This topic cover important geometrical figures including 2 D figures like rectangle, square, circle, triangle, parallelogram etc and 3 dimensional figures like cube, cuboid, cylinder, sphere, cone etc. This chapter cover how to calculate area and

Algebra is one of the core pillar of mathematics. Algebra topics are included in almost all classes from middle school to college level mathematics. Algebraic expressions are used to express relation between known and unknown entities which will help us to solve a given mathematic problem in algebra. Algebraic identities are used to simplify algebraic

Comparing quantities topic is part of basic arithmetic and real world mathematics. It covers topics like comparision between ratios, impact of profit, loss, discount, taxes on prices and impact of rate on money transactions for simple interest and compound interest. All of these are part of our day to day routine, and the objective of
