Introduction to Algebra

What is Algebra?

Algebra is a branch of mathematics in which letters and symbols are used to represent numbers and quantities in formulas and equations. It allows us to solve mathematical problems by using variables and operations.

Basic Concepts in Algebra

1. Variables: In algebra, letters such as x, y, and z are used to represent unknown quantities or values.

2. Expressions: An algebraic expression is a combination of variables, constants, and operations (like addition, subtraction, multiplication, and division).

3. Equations: An equation is a mathematical statement that shows the equality of two expressions. It typically contains an equal sign (=).

4. Terms: In an algebraic expression, terms are the parts separated by the addition or subtraction signs.

5. Coefficients: The coefficient of a term is the numerical factor that is multiplied by the variable.

Operations in Algebra

1. Addition and Subtraction: In algebra, we add or subtract like terms by combining the coefficients of the same variables.

2. Multiplication and Division: We use multiplication and division to simplify algebraic expressions and solve equations.
