1. Definition of term
The algebraic expression -3x2 is a term and 2a5 is another term.
A term is a conjoint constituted by four elements: the sign, the coefficient, the literal part and the exponent.
-3x2 The sign here is negative, the coefficient is 3, the literal part is x and the exponent is 2.
+2a The sign is positive, the coefficient is 2, the literal part is a but it has no exponent. When a term has no exponent it is supposed that the exponent is 1.
7n5 It has no sign, so it is supposed that the sign will be positive, the coefficient is 7, the literal part is n and the exponent is 5.
-n3 It has negative sign, no coefficient and is supposed that its coefficient is 1, its literal part n and the exponent 3.
x It has no sign and it is supposed that is positive. It has no coefficient, so it is supposed it is 1. Its literal part is x. It has no exponent, so we supposed it will be 1.
A term without a literal part is called an independent term.
