Start Learning NowWelcome to Chapter 7: Finding the Unknown from your Class 7 Maths book, Ganita Prakash Part 2. This chapter is the true start of your journey into algebra, and Teachoo is the best place to begin.
This chapter introduces one of the most powerful ideas in mathematics: algebraic equations. We'll start with fun visual puzzles, like balancing scales and mobiles, to figure out the value of a mysterious, unknown object.
We will then learn how to translate these puzzles and real-world problems into the language of algebra. This is where we learn to frame an equation.
In this chapter, we will study:
What an Equation is: Understanding the idea of a "balanced scale," where the Left Hand Side (LHS) must equal the Right Hand Side (RHS).
Framing Equations: How to convert word problems and puzzles into a mathematical statement with an unknown (like x or y).
Solving Equations Systematically: We'll learn the most important rule: what you do to one side of the equation, you must do to the other.
Using Inverse Operations: How to use addition/subtraction and multiplication/division to "undo" operations and find the value of the unknown.
Equations with Unknowns on Both Sides: We'll master how to solve equations where the unknown appears on both sides of the '=' sign.
The systematic methods for solving for the unknown are fundamental to all future math, and they are explained perfectly on Teachoo.
This is a crucial chapter, and Teachoo is the best place to build a strong foundation.
