A number is positive if it is greater than zero. A number is negative if it is less than zero. A number is non-negative if it is greater than or equal to zero. A number is non-positive if it is less than or equal to zero.

Non-integers are any number that is a decimal, fraction, or mixed unit. These are all not integers: Decimals: 3.14; 0.428571428571; 1.414213562373095. 3.14 ; 0.428571428571 ; 1.414213562373095. Fractions: ½; ¾; ⅞; 1½; 9/3; 3/7.

A integer is any number that is not either a decimal or a fraction (however, both 2.000 and 2/2 are integers because they can be simplified into non-decimal and non-fractional numbers), this includes negative numbers. A whole number is any positive number(0 through infinity) (including non-integers)

0

A non negative integer is an integer that that is either positive or zero. It’s the union of the natural numbers and the number zero. Sometimes it is referred to as Z*, and it can be defined as the as the set {0,1,2,3,…,}. Z, the set of integers, is defined as {…,-3,-2,-1,0,1,2,3,…}.

Integers are like whole numbers, but they also include negative numbers but still no fractions allowed! We can put that all together like this: Integers = { …, −4, −3, −2, −1, 0, 1, 2, 3, 4, }

No, negative integers are not a part of natural numbers, they are derived from natural numbers just like fractions. No, negative integers are not a part of natural numbers, they are derived from natural numbers just like fractions.

An integer (pronounced IN-tuh-jer) is a whole number (not a fractional number) that can be positive, negative, or zero. Examples of integers are: -5, 1, 5, 8, 97, and 3,043. Examples of numbers that are not integers are: -1.43, 1 3/4, 3.14, . 09, and 5,643.1.

Key Difference: An integer refers to a whole number meaning that it is not in the form of a fraction. Integers comprise of whole numbers as well as their opposites. A number can be described as a mathematical value that is represented through a word, symbol or figure. Integers also include negative numbers.

RULE 1: The product of a positive integer and a negative integer is negative. RULE 2: The product of two positive integers is positive. RULE 3: The product of two negative integers is positive. RULE 1: The quotient of a positive integer and a negative integer is negative.

Answer. Answer: The rule states that if the signs of the two integers are different then the final answer will be negative.

To add integers having the same sign, keep the same sign and add the absolute value of each number. To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite.

To add and subtract numbers always begin counting from zero….Two signs

• When adding positive numbers, count to the right.
• When adding negative numbers, count to the left.
• When subtracting positive numbers, count to the left.
• When subtracting negative numbers, count to the right.

This is in fact the reason why the negative numbers were introduced: so that each positive number would have an additive inverse. The fact that the product of two negatives is a positive is therefore related to the fact that the inverse of the inverse of a positive number is that positive number back again.
