Algebra is a branch of mathematics that deals with symbols, letters, and numbers used to represent relationships and solve problems. Instead of working only with specific values, algebra allows us to write general rules and formulas using variables (like x, y, or z). It involves operations such as addition, subtraction, multiplication, and division, but applied to unknown values as well as known ones. Algebra helps in solving equations, analyzing patterns, and understanding relationships between quantities. It forms the basis for more advanced topics in mathematics and is widely used in science, engineering, economics, and everyday problem-solving. By learning algebra, students develop logical thinking and problem-solving skills that are essential for higher-level math and real-world applications.
