Question

What is numerical coefficient?

Answer 1

Hint: As we know that a coefficient is any constant or numerical term that is in front of one or more variables is defined as a fixed number that is multiplied to a variable. It is mainly a multiplicative factor in some term of polynomial, a series or any expression. In this question we have to define what a numerical coefficient is.

Complete step-by-step answer:
We know that the term “numerical” is related to numbers i.e. it means the natural number. A numerical coefficient is any constant term that is in front of one or more variables in mathematical expression.
Let us take an example: \[3x + 2y + 4\]. In this equation we can say that $3$ is the coefficient of the variable $x$ while $2$ is the coefficient of another variable $y$. These are the numerical coefficients.
Also $4$ is not a coefficient, as it is not being multiplied by a variable.
Hence this is the definition of a numerical coefficient.

Note: We should know that a numerical coefficient is defined as an affixed number. We should note that when in any expression there is no any number in front of the variable., then it does not mean that it does not have any numerical coefficient. $1$ is always in front of it. As for example, $x + 2y + 9$, here in this expression the numerical coefficient of $x$ is $1$.
