Did you know that the distance between the earth and the sun is approximately 149.12 million kilometres? This is interesting, but what is more interesting is how do scientists calculate this distance? Did they travel? The answer is with the help of the concept of ‘Mensuration’. It is a branch of mathematics concerned with ascertaining …
When we talk about math, we think of numbers and shapes. Do you know there is a branch of mathematics that deals with letters as well? Yes! You heard it correct. Algebra is a field of mathematics that contains alphabetical letters along with numbers. These letters are referred to as ‘Variables’ in the world of …
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 …
Take a piece of paper and draw an image of a butterfly. You will definitely draw it in such a way, that both sides of the butterfly will be an exact replica of each other. If you fold one-half of the butterfly on the other, they will exactly overlap each other. Such figures with evenly …
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 …
