Algebraic notation is a system used to represent mathematical expressions and equations using symbols and letters. In this notation, letters such as x, y, and z typically represent variables, while numbers represent constants. This allows for concise communication of mathematical ideas and operations, making it easier to solve problems. In algebraic notation, operations like addition, subtraction, multiplication, and division are represented by symbols: +, −, ×, and ÷. Parentheses are used to indicate the order of operations, ensuring that calculations are performed correctly. This standardized approach is essential for studying and understanding algebra in mathematics.
