2) Algebra- Algebra is a branch of mathematics that deals with symbols and the rules for manipulating these symbols to solve mathematical equations and express mathematical relationships. It involves the study of mathematical symbols and the rules for manipulating these symbols to solve equations and analyze mathematical structures.
In algebra, letters (known as variables) are used to represent numbers or unknown quantities. Algebraic expressions are formed by combining numbers, variables, and mathematical operations such as addition, subtraction, multiplication, and division. Equations are statements that assert that two expressions are equal, and solving equations involves finding the values of variables that make the equation true.
Some key concepts in algebra include:
- Variables and Constants: Variables are symbols used to represent unknown quantities, while constants are fixed values. Variables are often represented by letters such as x, y, or z.
- Expressions: Algebraic expressions are combinations of variables, constants, and mathematical operations. For example, 3x + 5y is an algebraic expression.
- Equations: Equations are statements that assert that two expressions are equal. They contain an equal sign (=). Solving equations involves finding the values of variables that make the equation true.
- Linear Equations: Linear equations are equations where the highest power of the variable is 1. They can be represented as ax + b = 0, where a and b are constants.
- Quadratic Equations: Quadratic equations are equations where the highest power of the variable is 2. They can be represented as ax^2 + bx + c = 0, where a, b, and c are constants.
- Functions: Functions are mathematical relationships between input values (arguments) and output values. They can be represented by equations and graphs. For example, f(x) = 2x is a linear function.
- Inequalities: Inequalities compare two expressions and indicate that one is greater than, less than, or equal to the other. For example, x > 3 or y ≤ 2x + 1 are inequalities.
- Systems of Equations: Systems of equations involve multiple equations with multiple variables. The goal is to find a solution that satisfies all the equations simultaneously.
Algebra plays a crucial role in various areas of mathematics, science, engineering, economics, and many other fields. It provides a powerful tool for modeling and solving problems involving unknown quantities and relationships between variables.

Case Study on Class 6 Maths 2) Algebra
Using Algebra to Solve a Real-Life Problem
Let’s consider a case study that demonstrates how algebraic concepts taught in Class 6 mathematics can be applied to solve a real-life problem.
Case Study: Buying School Supplies
Scenario: John is a Class 6 student who wants to buy some school supplies for the upcoming academic year. He wants to calculate the total cost of the items he needs, including notebooks and pens, to plan his budget accordingly.
Given Information:
- The cost of each notebook is $2.
- The cost of each pen is $1.50.
- John wants to buy ‘n’ notebooks and ‘p’ pens.
Problem: John wants to determine the total cost of buying ‘n’ notebooks and ‘p’ pens.
Solution: To solve this problem, we can use algebraic expressions and equations.
Step 1: Define Variables: Let’s use the variable ‘n’ to represent the number of notebooks and ‘p’ to represent the number of pens.
Step 2: Formulate the Expressions: Based on the given information, we can formulate the following algebraic expressions:
- The cost of ‘n’ notebooks: 2n dollars.
- The cost of ‘p’ pens: 1.50p dollars.
Step 3: Create an Equation for Total Cost: To find the total cost, we need to add the cost of notebooks and the cost of pens. Therefore, we can create the following equation: Total Cost = Cost of Notebooks + Cost of Pens
Total Cost = 2n + 1.50p
Step 4: Solve the Equation: If John wants to buy 5 notebooks (n = 5) and 10 pens (p = 10), we can substitute these values into the equation and solve for the total cost.
Total Cost = 2(5) + 1.50(10) Total Cost = 10 + 15 Total Cost = 25 dollars
Therefore, the total cost of buying 5 notebooks and 10 pens is $25.
Conclusion: Through this case study, we can see how algebraic concepts, such as using variables, formulating expressions, and solving equations, can be applied to solve real-life problems. John was able to calculate the total cost of buying school supplies by using algebraic expressions and substituting values into equations. This application of algebraic thinking helps develop problem-solving skills and enables students to make informed decisions in everyday situations.
