RS Aggarwal Solutions Class 6 Chapter-6 Simplification (Ex 6B) Exercise 6.2

‘Simplification’ is Chapter 6 of Class 6 Mathematics. In this chapter, students will learn about the simplification, formulas for simplification, process of simplification, and examples of simplification. Simplification is basically simplifying an algebraic expression that can be defined as rewriting an expression in its most efficient and simplest form without changing the meaning of the original expression. It is generally like replacing mathematical expressions into shorter equivalent expressions. From RS Aggarwal solutions for Chapter 6 under exercise 6.2, students will understand that simplification is basically  putting something in simplest form. In general, it becomes simpler when it is easier to use. Simplifying is like doing something that is less complicated or less messy. To simplify the mathematical expression, students just need to eliminate unnecessary numbers or terms, usually done by eliminating or factoring them. Simplification can refer to the construction of a number problem that is in less complicated form of similar terms in an algebraic expression. The simplest form of a number or expression is to just write it in basic form. For example, referring from RS Aggarwal Exercise 6.2 questions, the simplest ams straight form of a fraction is to simplify a fraction and write the fraction value in its simplest or smallest form by dividing the denominator and numerator by their common factor. Reduce the fraction value to the smallest number by eliminating the lowest common value for the numerator and denominator, or modify an algebraic expression by grouping and combining like terms. 

Just Start with this expression: 4x + 3x − 3

Compress the terms like: 7x − 3

It now becomes a little easier to use.

Simplification is sometimes very obvious, but it also depends on what students want to do. When simplifying any mathematical expressions, students can't just go from start like from left to right, multiply, add, subtract, etc. Some mathematical operations take over others and must be done first. In fact, mismatching these mathematical expressions  out of turn can give you the wrong answer and completely different expression results. For Simplification or to simplify an expression: Always remember the word  ‘BODMAS’, and the letters  B, O, D, M,  A,  S stand for:  Brackets , Of ,  Division,  Multiplication,  Addition  and  Subtraction  respectively. Always try to remove brackets, unnecessary terms and numbers. According to the questions of Exercise 6.2 from RS Aggarwal the solutions that are referred to are like always going through the BODMAS rule. In RS Aggarwal all the solutions are in very simplified ways and for Exercise 6.2 of Chapter 6 - Simplification, there are solutions for every type of questions so RS Aggarwal is very useful for solving the question of simplification from Exercise 6.2.

What is an Algebraic Expression according to the RS Aggarwal Solutions?

The following are the basic rules and steps for simplifying a mathematical expression in accordance with Class 6 RS Aggarwal:

• Always use the BODMAS rule for simplification.

• Remove all the grouping symbols if any, such as brackets and parentheses by multiplying factors.

• Try to use the exponent rule to remove grouping if the terms are containing exponents.

• Combine the similar terms by addition or subtraction.

• Combine the constants.

• Multiplication and Division have the same priority so any operation can be performed firstly, but always before Addition and Subtraction.

• Addition and Subtraction have the same priority so any operation can be performed firstly, but always after Multiplication and Division.
