Mathematical statements use two types of quantities: constants
A constant is a symbol whose value does not change .
Examples: 26, -6, 2.71828, 2 ,
A rational expression is a fraction in which the numerator and
denominator are polynomials.
For example, the expressions below are rational expressions.
