Chapter 1: Introduction to Algebra

1. What is Algebra?
   • Example: Think of algebra as a puzzle. If you know there are 10 apples, but only 7 are visible, algebra helps you figure out that 3 apples are hidden by using a simple equation like 7 + x = 10.
2. History and Importance of Algebra
   • Example: Algebra is like the math version of a universal language. It's used in everything from solving everyday problems to helping engineers design bridges.
3. Basic Symbols and Terms
   • Example: If you have 2 pencils and want to buy more, algebra lets you express this as 2 + x, where "x" is the number of pencils you plan to buy.
4. The Role of Algebra in Mathematics
   • Example: Imagine doubling a recipe. Algebra helps you easily adjust the ingredients by using equations to keep everything in balance.
