As we learnt about the equation, how they satisfied both sides in Algebraic equation.

Equations use the equality (=) sign. Here we will learn with equations with linear expressions in one variable only. Such equations are known as linear equations in one variable.

The equations with linear expressions in one variable only. Such equations are known as linear equations in one variable. Continue Learning

A quadrilateral is a polygon with 4 sides, edges and four vertices or corners. Sometimes, the term quadrangle is used, by analogy with triangle. The total of its interior angles of quadrilaterals has 360 degrees.

3.2 Polygons

A simple closed curve made up of only line segments is called a polygon. Continue Learning

4.1 Introduction

As we learnt about the Geometry, that's tell us about the different type of shapes, about their properties, measurements, volumes etc.

Here we learn more about the quadrilaterals having different shapes, sizes, measurements etc. Continue Learning

5.1 Looking for Information

The data is the collection of information of all such cases is called data.

Data can be anything that share the information's about such object, like- your daily routine, your study, your breakfast, your marks, your game scores etc.

Organize the data in a systematic manner and then interpret it accordingly. Sometimes, data is represented graphically.Continue Learning

We have learnt about the square that has the equal sides. Side represent the length of surface of shape. We can find the area of square like (side x side). In similarly the square of any number is (number x number or a x a = a²) in number square system 2 is the square of a.

The square root of a number n is a number that, when multiplied by itself, equals n. Continue Learning

7.1 Introduction

A cube has three-dimensional solid shape and bounded by six square faces, facets or sides, with three meeting at each vertex.

7.2 Cubes

Numbers obtained when a number is multiplied by itself three times are known as cube numbers.

For example 1, 8, 27, ... etc. Continue Learning

8.1 Recalling Ratios and Percentages

We have already learnt that ratio means comparing two quantities and about the percentage, it also come from the ratio.

As we say about the ratio about a basket has 20 mango and 80 grapes than we say 20:80 in similarly in out of 100 it's called 20% mango and 80% grapes.

Yes, Percentage means any ratio or number will be out of 100 and percentage is denoted by % symbol. Continue Learning

9.1 What are Expressions?

We have learnt already and become familiar with what algebraic expressions (or simply expressions) are. Express or elaborate or expanse more about the thing that we discussing. Examples of expressions are:

x + 3, 2y − 5, 3x², 4xy + 7 etc. Continue Learning

We have learnt about plane shapes and solid shapes. Plane shapes have two measurements like length and breadth and therefore they are called two-dimensional shapes whereas a solid object has three measurements like length, breadth, height or depth. Hence, they are called three-dimensional shapes. Also, a solid object occupies some space.

Two-dimensional and three-dimensional figures can also be briefly named as 2-D and 3-D figures. Continue Learning

The Mensuration is the branch of mathematics, in which we deals with the study of different geometrical shapes and their areas and Volume.

As we have learnt in the previous classes about the different shapes of area, perimeters etc.

Here we will also learn about surface area and volume of solids such as cube, cuboid and cylinder. Continue Learning

12.1 Introduction

We learnt about the exponents in previous class. Any large number has converted in corresponds to the number of times the base is used as a factor known as exponent.

Power is an expression that represents repeated multiplication of the same factor.

Here we will learn more things about eh exponents and powers. Continue Learning

When purchasing cost will be increased than selling price will be automatically increased, this is called the direct effect.

In same way of effect will be shown when you alone doing some task and taking 4 hrs and if someone join with you and that job done in 1 hr, this is indirectly effect on the job.

13.2 Direct Proportion

If the value of x increases, value of y also increases in such a way that the ratio Continue Learning

14.1 Introduction

Factorization or factoring is the process that consists of writing a number or another number as a product of several factors, usually smaller or simpler objects of the same kind.

A factor is a number that divides that the given number. 

Here we will express algebraic expressions as products of their factors or Factorization. Continue Learning

Graphs are visual representations of data collected. Data can also be presented in the form of a table; however a graphical presentation is easier to understand.

We learnt something about the graphs in previous class where we see the bar graphs, Pictographs etc. we learn here more about these. Continue Learning
