A coefficient is a numerical or constant factor that multiplies a variable in a mathematical expression or equation. In simpler terms, it is the number in front of a variable.

For example, in the expression \( 3x + 5y - 2 \), the coefficients are:

- 3 for the variable \( x \),
- 5 for the variable \( y \).

If a variable does not have a number in front of it, the coefficient is understood to be 1. For instance, in \( x \), the coefficient is 1.
