Notation and terminology

[edit]
The plus sign

Addition is written using the plus sign "+" between the terms; that is, in infix notation. The result is expressed with an equals sign. For example,

(verbally, "one plus one equals two")
(verbally, "two plus two equals four")
(see "associativity" below)
(see "multiplication" below)

There are also situations where addition is "understood" even though no symbol appears:

Columnar addition:
  • A column of numbers, with the last number in the column underlined, usually indicates that the numbers in the column are to be added, with the sum written below the underlined number.
  • A whole number followed immediately by a fraction indicates the sum of the two, called a mixed number. For example,
          3½ = 3 + ½ = 3.5.
    This notation can cause confusion since in most other contexts juxtaposition denotes multiplication instead.
