Dividing Real Numbers
In a set of numbers, an operation under which a pair of elements (a, b) in this set, is made to correspond to a number q of this set so that this relationship is true: a ÷ b = q or a = b × q.
The result of a division operation is called the quotient.
The operation of division also translates other concepts such as successive subtraction, comparisons between quantities, sharing, a ratio, etc.
Symbol
Many symbols are used to represent a division operation, depending on the context:- a : b (The colon is commonly used to express a ratio between the numbers a and b).
- a ÷ b (This symbol is also called an "obelus" and it is commonly used in arithmetic in primary (elementary) school or elsewhere when solving arithmetic and non-algebraic calculations).
- a/b (The slash is used to represent fractions online; it is not very common in math texts, but it is present everywhere in technology).
- [latex]\dfrac{a}{b}[/latex] (This horizontal bar is used in fractional notation to represent the division of a by b in a numerical or algebraic expression).
