NCERT Solutions for Class 7 Maths Chapter 12 Algebraic Expressions In Hindi
According to the NCERT Solutions for Class 7 Maths Chapter 12 in Hindi, algebraic expressions are the use of letters or alphabets to represent numbers without providing their precise valuesStudents learned how to express an unknown value using letters like x, y, and z in the fundamentals of algebra. Therefore, specialists refer to these letters as variables. Variables and constants can both be used in an algebraic expression. A component is any value that is added before a variable and then multiplied by it.
An expression that includes variables, constants, and algebraic operations is known as an algebraic expression in Mathematics (addition, subtraction, etc.). Terms combine to form expressions. Additionally, students can complete problems in worksheets for algebraic expressions that are offered by Extramarks experts for both online and offline use.
Below is an overview of the concepts of Variables, Constants, Terms and Coefficients as discussed in the NCERT Solutions for Class 7 Maths Chapter 12 In Hindi:
In Mathematics,
 A variable is a symbol that doesn’t have a set value. Any value may be used. n is a variable that can have the values 1, 2, 3, in the example with the matchsticks above. Mathematics variables include things like a, b, x, y, z, m, etc.
 A constant, on the other hand, is a symbol that has a set numerical value. Every number is a constant. Constants include numbers like 3, 6, (1/2), 5, etc.
 A term is a variable alone (or) a constant alone (or) it can be a combination of variables and constants by the operation of multiplication or division. Some examples of terms are 3×2, (2y/3), √(5x), etc.
 Here, the numbers that are multiplying the variables are 3, 2/3, and 5. These numbers are called coefficients.
The many sorts of algebraic expressions are determined by the variables included in each expression, the number of terms in each expression, and the magnitudes of the variable exponents in each expression. The algebraic expressions are broken down into five separate categories in a table that is available on the Extramarks website and mobile application. It can be examined by students to help them understand the concepts and ideas in the NCERT Solutions for Class 7 Maths Chapter 12 In Hindi.
There are numerous branches in Mathematics. Arithmetic is the division that controls numbers and their operations. Calculations involving numbers, such as addition, subtraction, multiplication, and division, are performed using it. Geometry is the study of figures’ shapes, dimensions, and construction with the use of a compass, ruler, and pencil. Another intriguing division that takes the form of numbers and letters that we refer to as variables to explain our everyday circumstances is algebra. Algebraic expressions include variables, numbers, and operational signs. Examples include multiplication, division, exponentiation with the natural exponent, addition, and subtraction. Fractional expression is the name given to division in an algebraic expression with variables.
Rational numbers are those that can be expressed in fractional form. Examples include recurring decimals, integers, and decimal terminations.
An algebraic expression is referred to as being irrational if it contains the variable’s root or a fractional power with a changeable base. Therefore, using algebraic terms can be both rational and illogical. Integral and fractional expressions are two categories of rational expressions.
To learn mathematics, students must comprehend what an expression and an equation are. The aforementioned concepts have been further discussed in extensive detail in the NCERT Solutions for Class 7 Maths Chapter 12 In Hindi.
Finding the simplified term of the given expression is the aim of algebraic expression simplification. Students must first understand how to join similar terms, how to factor a number, the order of operations, and whether to factor the expression or simply simplify it before we can factor an algebraic equation. For the purpose of simplification, the constant terms are segregated and the variables that share the same degree are gathered along with the same terms. Students can learn how to simplify algebraic expressions through the NCERT Solutions for Class 7 Maths Chapter 12 In Hindi, available for access on the Extramarks website and Extramarks mobile application.
Below are a few important terminologies used in the NCERT Solutions for Class 7 Maths Chapter 12 In Hindi that students must understand before solving the NCERT Solutions for Class 7 Maths Chapter 12 In Hindi:
 An Expression: An algebraic expression is one that includes variables, integers, and operation symbols. In algebra, readers engage with variables, symbols, or characters whose meanings are unknown.
 There are four primary categories of algebraic expressions, including:
 Monomial Expression.
 Binomial Expression.
 Trinomial Expression.
 Polynomial Expression.
 Monomial Expression: A singleterm algebraic expression is referred to as a monomial.
 Binomial Expression: An algebraic expression with two unlikely terms is known as a binomial expression.
 Trinomial Expression: A trinomial is an algebraic expression with just three nonzero terms.
 Polynomial Expression: A polynomial is often defined as a term with nonnegative integral exponents for a variable.
