Coefficient
The number multiplied by a variable in a term.
In mathematics, a coefficient is a numerical or constant factor that multiplies a variable or an algebraic term. It is the term that precedes or follows a variable or algebraic expression. Coefficients are used in a wide range of mathematical applications, including algebra, calculus, linear equations, and polynomial functions.
For example, in the equation 3x + 2y = 7, the coefficients are 3 and 2. The first coefficient, 3, modifies the value of the variable x, while the second coefficient, 2, modifies the value of the variable y.
In algebraic expressions, coefficients can take on different values, including positive, negative, fractions, decimals, or even complex numbers. It is important to know how to compute with coefficients and how they affect the values of the expressions they are associated with.
