Negative Numbers

Definition

Negative Numbers are an extension of whole numbers for numbers less than zero. The − sign can be used to signify a binary operation, subtraction (i.e. 5 3) or a unary operator, negation (i.e. 3). As an unary operator, −3 refers to 3 less than 0.

Negative numbers are constructed through the extension of the number line and subtraction of a bigger number from a smaller number (Eg. 1 4 = −3).
