Q:

# What is the difference between positive integers and nonnegative integers?

A:

The only difference between the set of positive integers and the set of nonnegative integers is the inclusion of zero in the set of nonnegative integers. Zero is neither a positive number nor a negative number. It is considered a rational number, an even number and a real number.

The set of negative integers can be written as {..., -5, -4, -3, -2, -1}, while the set of positive integers can be written as {1, 2, 3, 4, 5, ...}. To include zero, the set of nonnegative integers can be written as {0, 1, 2, 3, 4, 5, ...}. An integer is any whole number, whether positive or negative. A whole number is a number that can be written without any fractions or decimals. The set of integers from negative five to positive five can be written as {-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5} and contains zero. Sometimes, the term "whole number" is used only to refer to zero and positive whole numbers, while the term "negative whole numbers" is used to refer to whole numbers to the left of zero. The terms "counting numbers" and "natural numbers" also refer to the set of positive integers.

The factors of a number are all the integers that can be multiplied together to produce that number. For example, 1, 2, 3 and 6 are all factors of 6. Multiples are all the numbers of which a given number is a factor.

Polynomial operations are basic math operations performed with polynomials instead of integers. A polynomial is an algebraic expression with more than one term. While there are algebraic polynomial operations, simple operations such as addition, multiplication, subtraction and division are also examples of polynomial operations.

The Monterey Institute explains that the graph of a linear inequality has a shaded region and that a set of ordered points (x, y) may be located within or outside of the shaded region. To find the values of x and y that satisfy an inequality, one must obtain a pair of ordered points within the region that satisfies the inequality, which includes the continuous boundary line.
