How do you write a divisibility symbol?

The divisibility of a by b is denoted by the symbol b|a. c|a and c|b⇒c|a±b . The last two properties are equivalent to saying that the set of elements divisible by b forms an ideal, bA, of the ring A (the principal ideal generated by the element b), which contains b if A is a ring with a unit element.
