The number or algebraic expression written below the fractional line in a fraction is called the denominator. Fractions with known denominator are called algebraic expressions, and fractions with unknown denominator are called fractions. Denominator should not be zero.

Fraction (from Latin, "broken") stands for a part of the whole, or more generally, any equal number of parts. In daily spoken English, scores describe parts of a certain size, such as one-half, five-eighths and three-quarters. Molecules and denominators are also used for uncommon fractions, including compound fractions, complex fractions and mixed numbers.

Quotient, whose formula is: (Dividend-Remainder) Divider = Quotient, is a mathematical term.

In a division formula, the relationship among dividend, remainder, divisor and quotient is: (dividend-remainder) ÷ divisor = quotient, which is recorded as dividend ÷ divisor = quotient ÷ remainder, and then the quotient × divisor+remainder = dividend is derived.

Algebra is a branch of mathematics, which studies the general solutions and properties of numbers, quantities, relationships, structures and algebraic equations (groups). Elementary algebra is generally taught in middle schools, introducing the basic ideas of algebra: studying what happens when we add or multiply numbers, understanding the concept of variables and how to establish polynomials and find their roots.

The research object of algebra is not only numbers, but various abstract structures. Among them, we only care about various relationships and their nature, but we don't care about the question "what is the number itself". The common types of algebraic structures are groups, rings, fields, modules, linear spaces and so on.

A true fraction is a fraction in which the numerator is smaller than the denominator. The fractional value of the true fraction is less than 1. Such as: 1/2, 3/5, 8/9 and so on. Equal to 1 is a false fraction. Real scores are generally learned in a positive range.
