A term is a mathematical expression that may form a separable part of an equation, a series, or another expression.
In the context of polynomials, sometimes term is used for a monomial with a coefficient: to 'collect like terms' in a polynomial is the operation of making it a linear combination of distinct monomials.
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. Terms are numbers separated by the operational signs of addition and subtraction in an expression. For example, in , , , and are all terms.
Some Terminology 
- 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).
