coefficient. n. 1. (Mathematics) maths. a. a numerical or constant factor in an algebraic term: the coefficient of the term 3xyz is 3. b. the product of all the factors of a term excluding one or more specified variables: the coefficient of x in 3axyz is 3ayz.
A term can be a signednumber, a variable, or a constant multiplied by a variable orvariables. Each term in an algebraic expression is separated bya 1 sign or 2 sign. In, the terms are: 5 x, 3 y, and 8.When a term is made up of a constant multiplied by a variableor variables, that constant is called a coefficient. In the term5 x, the coefficient is 5.In some terms, the variables will have exponents, such as .This exponent determines the degree of that term. â¢ The degree of is 2.
