What is a term in algebra?

In algebra, a term is a fundamental building block that can consist of a single number (known as a coefficient), a variable, or a combination of both, possibly multiplied together. The definition encompasses the idea that terms can be as simple as a solitary number, like 5, or a variable, such as x, but more complex terms are combinations of coefficients and variables, such as 4y or 3x^2. This broader understanding means that terms can represent a single part of an expression and are instrumental in forming equations where they play a crucial role in operations like addition or multiplication.

This makes the choice that describes a term as "a combination of variables and coefficients" the most accurate representation of the concept in algebra since it captures the essence of what constitutes a term in polynomial expressions and equations. A simple variable by itself or just a number does not encapsulate the full range of what a term can be, nor does the total result of an equation accurately describe a term, as it refers to the complete value resulting from an equation rather than its individual components.
