The world of numbers is infinite and interesting. Till now, we have understood the concepts of natural numbers, whole numbers, integers, and rational numbers. But now the question is, are all these numbers real? That question must have surely taken your breath away, but don’t you worry. In this chapter, we take a look at …
You must be well aware of variables, such as x,y,z, and constants such as 5, ⅜, 10. Whenever you see a combination of variables and constants, there is a good chance that it might be polynomial. You will be surprised to know that polynomial is hidden everywhere in one way or another, from your phone …
In our previous grades, we have studied the methods to solve a linear equation. In this chapter, we further advance our knowledge by solving complex word problems in simpler ways. The chapter deals with finding the solution for a problem, by graphical representations as well as expressing it algebraically. Linear equations in two variables consideres …
Imagine you are in a supermarket to take milk and eggs, but you are also in a hurry. Now if you go on to search the entire place, you are going to be late for sure. So what can be done? Well, how about asking a store representative for guidance? They will direct you at …
Word problems always make you sweat in stress. One reason for this is because of the confusing questions asked. For instance – try finding an answer to this question – Bob and Martha have 45 chocolates. They gave 15 chocolates to Cathy. How many chocolates does Bob have? All that we know is – Bob …
Take a notebook and a pen, and draw a point on it. Now, measure the point that you’ve drawn. Did you get an answer? No? It’s because the point is not actually a geometrical figure. What we draw is an indicator, not a figure. Isn’t this interesting? Want to know more such interesting facts? Let’s …
In mathematics, various shapes are either 1-dimensional, 2-dimensional or 3-dimensional. In the previous grades, you might have learnt about some of them consisting of lines, squares, cubes and many more. In this chapter, we will learn in detail about lines and angles. We will explore different types of angles, like the adjacent and complementary angles. …
Triangles are polygons with least number of sides, i.e three. Interestingly you can divide any complex polygon into several triangles. This method is often used to calculate the area of a complex polygon by breaking it into triangles, thus reducing the complexity of calculation. Watch our videos to learn more about triangle, right-angled triangle, isosceles …
Shapes like squares, rectangles, rhombus, parallelogram are all Quadrilaterals. And what is a quadrilateral? We have already studied this in the previous grades. Quadrilaterals are the shapes that have 4 sides, 4 angles, and 4 vertices. Want to know what conditions will categorize a quadrilateral as trapezium or a rhombus? Follow our videos to explore …
Wondering why this chapter is named as the area of parallelogram and triangle? What is the relation between them? To your surprise, a parallelogram is made from at least two triangles! Does it help us in any way? It surely does. Based on this, we can easily find the area of a parallelogram. There are …
