Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols. It's all about finding the unknown or putting real life variables into equations and then solving them. Let's dive into some basic concepts!
- Variables: Symbols that represent numbers or values. For example, in the equation x + 2 = 5, x is the variable.
- Expressions: Combinations of variables, numbers, and operations. For instance, 3x + 2 is an expression.
- Equations: A statement that two expressions are equal. Like 3x + 2 = 11.
