Definition of coefficient

What's before the variable

In layman's terms: A coefficient is simply the number before an algebraic variable or term.

In technical 'math speak', the coeffienct is a constant .

Examples of coefficients

Algebraic expression	The expression's coefficient
3x	3
5y	5
11x²	11
11xy	11 (remember the coeffienct must be a number)
x	1 * Whenever the coefficient is '1', it is generally not written. (This is explained by the multiplicative identity)
4xyk	4
xy	1 (Again when the coefficient is 1 people normally do not write the '1')
