A term is a mathematical expression which may form a separable part of an equation, a series, or another expression.
Definition[change | change source]
- 3 + 4x + 5yzw
3, 4x, and 5yzw are three separate terms.
In the context of polynomials, term can mean a monomial with a coefficient. To 'collect like terms' in a polynomial is the basic operation of making it a linear combination of distinct monomials. For example,
- 3x + 2x2 + 5x + 1 = 2x2 + (3+5)x + 1 = 2x2 + 8x + 1, with like terms collected.
In general mathematical use, however, term is not limited to additive expressions. Individual factors in an expression representing a product are multiplicative terms. Indeed, individual elements of any mathematical expression may be referred to as "terms".
Specific names for terms[change | change source]
- addition and subtraction
- Factor. In a multiplication of two factors, the first is called the multiplicand and the second is called the multiplier.
- divisions and fractions
- The top of a division is called the numerator (or dividend), and the bottom is called the denominator (or divisor).
- term value
- the value of the term such as the term value of 8a, if a=1, is 8.
