Term (mathematics)

A term is an operand or an operator in a mathematical expression.
Definition.
In an equation, the "terms" are all the numbers/variables (like formula_1 or formula_2) and all the operators (like formula_3 or formula_4). Terms can be grouped in brackets (often parentheses) in an overall expression. For example, in
3, formula_3, 4, formula_7, formula_3, 5 and formula_9 are seven separate terms.
A series is often represented as a sequence of terms (often a sum).
