Question: User: What is the coefficient?
1. The problem asks: What is the coefficient?
2. A coefficient is a numerical or constant factor that multiplies a variable in an algebraic expression.
3. For example, in the term $5x$, the coefficient is $5$.
4. If the term is $-3y^2$, the coefficient is $-3$.
5. If there is no number explicitly written, like in $x$ or $y$, the coefficient is understood to be $1$.
6. Coefficients can be positive, negative, whole numbers, fractions, or decimals.
7. To identify the coefficient, look for the number directly multiplying the variable(s).
Final answer: The coefficient is the number multiplying the variable in an expression.
