# Whole Numbers Basics

Whole Numbers are simply positive Integer numbers which starts from '0' and tends to infinity but not the negative integer numbers. The difference between whole numbers and Natural Numbers is that 0 is added in the whole numbers.

Whole number can be easily identified by some basic rules and properties:
1. Whole numbers doesn't contain a negative sign.
2. Whole numbers cant be a decimal or a fraction.
3. Whole numbers are closed under addition, subtraction, multiplication and division.
4. Whole numbers are commutative, associative and distributive in nature.

There are some basic operations performed by whole numbers. They are:

1. Whole number addition states that when two whole numbers are added we get a Whole Number.
e.g, 4 + 5 = 9

2. Whole number subtraction states that when two whole numbers are subtracted we get a whole number.
e.g, 9 - 2 = 7

3. Whole number multiplication states that when two whole numbers are multiplied we get a whole number.
e.g, 7 * 3 = 21

4. Whole number division states that when two whole numbers are divided we get a whole number.
e.g, 24 ÷ 4 = 6

## Line Segment

Line is a collection of points in a straight path that can be extended upto infinity. Since the line is extended to infinity its length cannot be measured. A Straight Line with arrow on both sides is used to denote a line.

A line segment is a part of the line that has two end points. Since the segment has two definite endpoints its length can be measured.   A st...Read More

## Ordering Whole Numbers

Whole numbers can be placed in an order. The whole numbers are ordered by a any Whole Number before, between or after the given Set of whole numbers. The whole numbers can be ordered easily by arranging them in a number line. The whole numbers can be ordered in two ways: ascending order and descending order.

1. Ascending Order

## Whole Number and Place Value

Whole number consists of all the positive integers along with 0. The place value of a digit in a Whole Number is said by the Position of the digit in the whole number. The place value of a number is ten times the place value of a number placed to the right of that number. A number can be separated into periods. Period is a group of three digits.  This table ...Read More

## Comparing Whole Numbers

While comparing whole Numbers, one should know about the counting of numbers. The whole numbers can be easily compared when placed on a number line. To compare whole numbers, there are 4 comparison symbols used:

1. Equal to Sign(=): This symbol is used to when the whole numbers to be compared are equal. It denotes that the Whole Number to its left side is equal...Read More

## Rays and Number Ray

A beam of light starts from its source but has no end. The light beam travels to an infinite distance. Hence the light beam is called a Ray. A ray normally has no end. In Geometry the ray is described as a part of the line.

A Whole Number ray is a number line starting with zero and extends to infinity. Since the number line of the whole number has no end it is compared with the ray and called whole number ray.

## Rounding Whole Numbers

Rounding is basically finding a less accurate but nearest number for calculations purpose. Generally we do not get exact answer by rounding off but it helps in heading easily for the calculation part.

There are some rules to round whole Numbers:

1. For any number which is to be rounded we have to check first the digits on the right hand side. If the r...Read More
