Question: 1 / 400

Which of the following is a characteristic of an algebraic expression?

It must contain a numeric value only.

It can include numbers, variables, and operators.

An algebraic expression is defined as a mathematical phrase that can include numbers, variables (which represent unknown values), and operators (such as addition, subtraction, multiplication, and division). This definition encompasses a wide variety of combinations, which can express different mathematical relationships and quantities.

For example, the expression 2x + 3 represents an algebraic expression where '2' is a coefficient, 'x' is a variable, and '3' is a constant. This flexibility allows algebraic expressions to be used in equations and inequalities, making them fundamental in algebra and higher mathematics.

Understanding that an algebraic expression can mix these elements is crucial for problem-solving in algebra, as this is the foundation for more advanced topics, such as algebraic equations and functions.
