A coefficient is a numerical factor applied to a variable in an algebraic expression. It is a constant that is multiplied by the variable.
For example, in the expression 3x + 4y, the coefficients are 3 and 4. The coefficient 3 is multiplied by the variable x, and the coefficient 4 is multiplied by the variable y.
Coefficients can be positive or negative, whole numbers or fractions, and play an important role in representing the relationship between variables in mathematical equations and formulas.

A coefficient is a numerical factor that multiplies a variable in an algebraic expression.
For example, in the expression 3x + 2y, the coefficients are:
- 3, which is the coefficient of the variable x
- 2, which is the coefficient of the variable y
The coefficient indicates how much the variable is multiplied by. In this case, x is multiplied by 3, and y is multiplied by 2.
Coefficients can be positive or negative numbers. They are an important part of algebraic expressions, as they determine the scale and impact of each variable term.
Understanding and working with coefficients is a fundamental skill in algebra, as they are used extensively in equations, formulas, and problem-solving. Being able to identify, manipulate, and interpret coefficients is crucial for success in mathematics.
