Whole Numbers


Natural numbers are the counting numbers {1, 2, 3, …} (the non-negative integers)

A whole number is a number that is not a fraction or a decimal. The whole numbers include all the natural numbers and Zero.

Integers are the natural numbers and their negatives {… −3, −2, −1, 0, 1, 2, 3, …}.





positive number is a number that is bigger than zero.  In business, positive numbers were used to represent assets.

negative number is a real number that is less than zero. Such numbers are often used to represent a value that is a deficit.

Negative numbers have many applications in business and personal finance. Example: How can we have less than nothing? When we’re in debt.

Two numbers that have the same magnitude but are opposite in signs are called Opposite Numbers. Example: +5 and -5 are Opposite Numbers

The absolute value (or modulus) |a| of an integer a is the numerical value of a without regard to its sign.  Example:  |-5| = 5
