Algebra Class 6 Notes CBSE Maths Chapter 11 (Free PDF Download)

• Algebra is a general form of arithmetic in which numbers are represented by letters that are joined according to arithmetic rules.

• We looked at matchstick patterns for producing letters and other forms. We learned how to express the general relationship between the numbers of matchsticks necessary to repeat a certain shape in writing. The amount of times a particular shape is repeated varies; it can be 1,2,3,... It's a variable that's represented by a letter like n.

• A variable's value can change over time; it is not fixed. A square's length can be any number. It's a variable, after all. The number of angles in a triangle, on the other hand, has a fixed value of three. It isn't a parameter.

• To represent a variable, we can use any letter, such as n, l, m, p, x, y, z, and so on.

• A variable allows us to articulate relations. Variables are numbers that do not have a set value. We can perform addition, subtraction, multiplication, and division on them in the same way that we do with fixed integers. We can create equations with variables like \[\text{x -- 3, x + 3, 2n, 5m, 3 p, 2y + 3, 3l -- 5}\], and so on by using various operations.

• Many common laws in geometry and arithmetic can be expressed in a general form using variables. The rule that the total of two integers remains the same if the order in which they are obtained is reversed, for example, can be written as \[\text{a + b = b + a}\]. The variables a and b can be any number, such as 1, 32, 1000 – 7, – 20, and so on.

• A condition on a variable is referred to as an equation. It is expressed by asserting that a variable expression equals a fixed number, such as \[\text{x - 3 = 10}\].

• An equation has two sides, LHS and RHS, with the equal (=) sign in the middle.

• Solution of an equation: The value of a variable in an equation that satisfies the equation is known as the solution.

• The trial and error approach is one method for obtaining the solution to an equation. We give the variable a value and see if it satisfies the equation using this way. We continue in this manner, assigning different values to the variable until we discover one that fulfils the equation.

• Only for a specific value of the variable in the equation is the LHS equal to the RHS. This definite value of the variable is said to satisfy the equation. This value is referred to as the equation's solution.

A Quick Overview of Class 6 Chapter 11 Algebra

Our study so far familiarized us with the numbers and shapes. We have studied numbers, properties of numbers, and operations on numbers. We have used our knowledge of numbers and shapes to solve our many issues in life. The branch of Mathematics in which we learned numbers is known as arithmetic whereas the branch of Mathematics in which we learned shapes is known as Geometry. In Chapter 11, we will be familiarized with the new branch of Mathematics known as Algebra.

The main aspect of Algebra is to make use of letters. With the help of the letters, we can write the Mathematical rules and formulas in a general way. Letters help us to talk about any number, not just any specific number. Secondly, letters may represent unknown quantities. 

By studying the method of determining unknown quantities, we have developed a powerful tool known as Algebra which helps us to solve puzzles and many problems in our daily life. Thirdly, letters represent numbers, and Mathematical operations can also be performed on letters as on numbers. This brings about the study of Algebraic expressions and properties. 

What is Algebra?

Algebra is the branch of Mathematics that replaces the letters for numbers and algebraic equations denote scale where what is performed on one side will also be performed on the other side and the number act as constants. Algebra involves complex numbers, real numbers, vectors, matrices, and many different forms of mathematical representations. 

With the help of Algebra, we can solve the Mathematical equations and derive unknown quantities such as percentage proportions and bank interest. The alphabetical letters in Algebra which are used to find unknown quantities are known as variables and the values which are known in algebra such as numbers are known as constant.
