A mathematical expression that contains either an algebraic term or interconnected unlike algebraic terms to represent a quantity is called an algebraic expression.

An algebraic expression is an expression in mathematical form and it represents a quantity mathematically. The mathematical expression is formed by either an algebraic term or interconnected two or more unlike algebraic terms. The unlike algebraic terms are actually interconnected by either positive sign $(+)$ or negative sign $(-)$ or combination of both signs.

$3a+4b-5c+6d$

It is a mathematical expression and it contains four algebraic terms but all of them are unlike terms. The unlike algebraic terms $3a$, $4b$, $5c$ and $6d$ are interconnected by positive and negative signs to form an expression.
