Coefficient
A number multiplied by a variable in an algebraic expression (can be positive or negative).
In mathematics, a coefficient is a numerical or constant factor that appears alongside a variable or a term in an algebraic expression. It is usually represented by a letter or a symbol and is used to multiply or divide the variable or term.
For example, in the expression 3x + 4y, the coefficients are 3 and 4. The coefficient 3 is multiplying the variable x, and the coefficient 4 is multiplying the variable y.
Coefficients are important in algebra because they help us manipulate equations and expressions. We can combine like terms by adding or subtracting their coefficients, and we can isolate variables by dividing both sides of an equation by their coefficients.
In basic algebra, coefficients are often used to solve linear equations or to simplify algebraic expressions. However, in more advanced branches of mathematics such as calculus or linear algebra, coefficients are used to represent more complex ideas such as derivatives or matrix operations.
