Understanding the difference between any two quantities is very important. The distinction helps us to identify which quantity is bigger and which is smaller. In this chapter, we will understand how to compare quantities, based on different factors. Here, we will learn about the profit-loss calculations, the percentage calculations and simple interest. This chapter will …
Numbers that start from zero are called as ‘Whole Numbers’. Numbers that come naturally are called as ‘Natural Numbers’. Numbers that are the combination of positive and negative numbers are called as ‘Integers’. We have learned all of these in our previous lessons. In this chapter, we will understand ‘Rational Numbers’. These are the numbers …
Numbers have helped us to count things easily. With the help of numbers, we can conveniently identify which collection of objects is bigger and arrange them in order. Numbers are used in many ways in different contexts. Calculations that deal with smaller numbers are easy and simple. But, is calculating bigger numbers as easy as …
When someone tells you to start counting, you definitely begin with 1, 2, 3 and so on! They come naturally when we start counting. Thus, mathematicians named them ‘Natural numbers’. But why do numbers starting from zero are called ‘Whole Numbers’? Because zero is a number that comes in the middle of positive and negative …
Division of smaller numbers is comparatively easy, but when it comes to bigger numbers like 982356 and 1987632, finding the solution takes a lot of time. To increase our pace of calculation with bigger numbers, we must learn some tips and tricks. Curious enough to know about them? What if we tell you that any …
As learned in the previous chapters, numbers that start with Zero are called ‘Whole Numbers’, on the other hand, numbers that come naturally, such as 1,2,3, and so on are called ‘Natural Numbers’. But what if we tell you that there are numbers that are placed before zero? Baffled? Don’t worry. There are a group …
What is half of a number? Let’s say, you are asked to find out the half of 19865472. Well, that is a very big number. But then, to find its half we must divide it by 2, and this can be written as 19865472/2. In this type of number, we get a numerator which is …
Decimals are very interesting concepts. They empower your mind to think beyond boundaries. For instance, if we are told to find the exact half of 9, we may divide it by 2 and get an answer, which is 4.5. In this particular example, we came to know that some digits exceed beyond points, and these …
Let say, there are 15 boys and 10 girls in your class. If we divide the number of boys with girls, we get an expression which is 3/2. This is simple maths, but hold on. Why did we divide the numbers after all? The answer is to get the ratio. This ratio provides us with …
