What is a Numerical Coefficient?

Answer: A fixed number that is multiplied by a variable is called a numerical coefficient.

Explanation:

A numerical coefficient is a number that is multiplied by a variable in an algebraic expression. In simpler terms, is a number that multiplies variables in a mathematical expression. It’s essentially a fixed value attached to a variable.

It’s the number that sits in front of a variable. For example, in the expression “3x”, the numerical coefficient is 3. Similarly, in the expression “-2y”, the numerical coefficient is -2.

Numerical coefficients can be positive, negative, or zero, and they represent the quantity by which the variable is multiplied.
