## FAQs on RS Aggarwal Solutions Class 6 Chapter-8 Algebraic Expressions (Ex 8B) Exercise 8.2

**1. What is an algebraic expression as mentioned in the CBSE Class 6 Maths textbook?**

Algebra is a part of Mathematics, dealing with numbers, letters and shapes. As of now, students have learnt to use numbers in mathematics but from this chapter, students will get to know how to use alphabets in mathematics. To understand algebra, we need to know what an algebraic expression and equation are. An algebraic expression is an expression having numbers, letters and mathematical operations like addition, subtraction and multiplication etc., in it. For example, 5x+6 is an expression, in this given expression, 5x and 6 are terms whereas “+” is the mathematical operation. To be precise, “x” is a variable. Variable’s value changes from time to time. On the other hand, a constant has a definite value. To know more about the algebraic expressions, please read the above-given PDF.

You can avail all the well-researched and good quality chapters, sample papers, syllabus on various topics from the website of Vedantu and its mobile application available on the play store.

**2. What is an algebraic equation as mentioned in the CBSE Class 6 Maths textbook?**

Algebra is a part of Mathematics, dealing with numbers, letters and shapes. As of now, students have learnt to use numbers in mathematics but from this chapter, students will get to know how to use alphabets in mathematics. To understand algebra, we need to know what an algebraic expression and equation are. An algebraic equation is also an expression, where the two sides of an equation are connected through the “=” symbol. It connects the L.H.S with the R.H.S. For example, 4x+2y+3=0. In this equation, 4x+2y+3 is the L.H.S and “0” is R.H.S. They are connected and equated with the symbol “=”.

**3. What is the difference between algebraic expressions and equations as mentioned in the CBSE Class 8 Maths textbook?**

Algebra is a part of mathematics, dealing with numbers, letters and shapes. To understand algebra, we need to know what an algebraic expression and equation are. An algebraic equation is also an expression, where the two sides of an equation are connected through the “=” symbol. An algebraic expression is an expression having numbers, letters and mathematical operations like addition, subtraction and multiplication etc., in it. An expression is the combination of letters, numbers, variables and constants. On the other hand, the equation is a joining of two expressions with the help of “=”. For example, 3+5 is an expression and 3+5= 8 is an equation. The end result of an equation is defined and hence solving the problem has a certain method.

**4. How to simplify algebraic equations?**

An algebraic equation is also an expression, where the two sides of an equation are connected through the “=” symbol. It connects the L.H.S with the R.H.S. For example, 4x+2y+3=0. In this equation, 4x+2y+3 is the L.H.S and “0” is R.H.S. The main purpose of solving the equation is to find the value of the unknown variable in the equation. In the first step, separate the constants to one side and variables on to the other side. This can be done with the help of mathematical operations like addition, subtraction, multiplication and division. This may also include solving the roots etc.,

To know more about solving the algebraic equations, please read the above-given PDF. try solving as many problems as you can to know how to use different mathematical operations properly.

**5. How does solving RS Aggarwal will help improve scores in maths for Class 6 CBSE students?**

RS Aggarwal is the standard book recommended by many experts, teachers. It is in perfect sync with the CBSE curriculum. It is designed by the experts after careful research into the previous year papers, exam patterns, reference materials and recent trends. Students face difficulty in solving math problems and with poor scores in it. With a proper strategy, guidance and continuous practice, they can overcome this fear and score well. To practice well, they should initially study their textbook thoroughly, then solve the given exercises in the textbook. If the students feel that they are good with the basics, they can go for reference books and solve the problems given in the reference books. Giving a mock test and solving these exercises will also help in improving time management skills and presentation skills.
