(noun) a coefficient is a number used to multiply a variable in an equation. It tells us how many times to use that variable. If we have 3x, the number 3 is the coefficient, and it means we have three times the value of x.

Example

In the equation 4x + 2y = 10, the number 4 is the coefficient of x.

Example

In the expression x^2, there is no visible coefficient in front of the x.

(noun) a coefficient can also describe a numerical value that expresses a relationship between different quantities, like how much something increases or decreases. For example, the coefficient of friction shows how easily two surfaces slide against each other.

Example

The coefficient of friction between rubber and concrete allows cars to grip the road well.

Example

If the coefficient of friction is very low, it means the surfaces slide easily without grip.
