👉 Expressions in mathematics are symbolic representations used to convey mathematical ideas, relationships, or operations. They typically consist of a combination of numbers, variables, mathematical symbols (like +, -, ×, ÷), and parentheses to group expressions. For example, "2x + 3" represents the expression where "x" is a variable, "2" is a coefficient multiplying "x", "+ 3" denotes addition, and the expression as a whole is evaluated to yield the result "2x + 3". These expressions can be used to define functions, solve equations, and express complex mathematical relationships concisely. They are fundamental in algebra, calculus, and other branches of mathematics, allowing for precise communication and problem-solving.
