The study of numbers, especially the properties of the traditional operations on them—addition, subtraction, multiplication and division.
 
Expansion of Numbers and Operations
(1) Natural numbers are closed under addition. (2) Subtraction is the inverse operation of addition. l + m = n , n - m = l Define negative integers then integers are closed under subtraction. (3) Multiplication is repeated addition. p + p + p = p × 3 p ...
