An algebraic expression say 2 × *x + y* ÷ 2 – 3 cannot be evaluated to a definite number as values of *x* and *y* are unknown. *x* and* y* may be given any values and the resulting value of the expression would differ as a result.

The expression is written in a more compact form as

2*x + y / *2 – 3

This expression has three algebraic terms. Terms of an algebraic expression are separated by + or – signs. 2*x*, *y / *2 and 3 are the three terms in the given algebraic expression. 2 and *x* are factors of the term 2*x*. *y / *2 has factors 1 / 2 and *y*.
