Ever wondered why every ice-cream cone is exactly the same in terms of design, length and volume? How do they do it? It’s simple. In Geometry, we use specific tools to design, construct and measure the shapes. In this way, we achieve the exact figure that we desire. In this chapter, we will learn how …
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 …
When you look at the objects around you, they all have a specific shape. Some are triangular, some rectangular and so on! The field of mathematics that deals with shapes, sizes, the position of figures, and properties, is called ‘Geometry’. The world of geometry extends wider. A simple triangle has different types, whereas a rectangle …
The objects we see around us come in different shapes and sizes. These shapes are formed using curves and lines. Any shape includes various details, for example – a vertice at the corner, a plane on which it forms, etc. But, how do we know mathematically if a shape is smaller or bigger? To identify …
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 …
Suppose you have to make a list of all the books in your cupboard, or have to maintain a record of all the tasks you performed the previous week. How would you usually go about this then? It’s pretty simple. You will create a table and arrange all the names and numbers in the respective …
