20 Examples of Whole Numbers

The integer numbers They are those that express a complete unit, so that they do not have an integer part and a decimal part. Eventually integers can be thought of as fractions whose denominator is the number one. For example: 430, 12, -1, -326.

When we are little they try to teach us math with an approach to reality and they tell us that the integers represent what exists around us but cannot be divided (people, balls, chairs, etc.), while the decimal numbers they represent what can be divided in the desired way (sugar, water, distance to a place).

This explanation is somewhat simplistic and incomplete, since the integers also include, for example, the negative numbers, that escape this approach. The integers, moreover, belong to a larger category: they are in turn rational, real and complex.

Examples of whole numbers

Here several integers are listed as an example, also clarifying the way in which they should be named with words in Spanish:

1. 430 (four hundred thirty)
2. 12 (twelve)
3. 2.711 (two thousand seven hundred eleven)

4. 1 (one)
5. -32 (minus thirty two)
6. 1.000 (one thousand)
7. 1.500.040 (one million five hundred thousand forty)
8. -1 (minus one)
9. 932 (nine hundred thirty two)
10. 88 (eighty-eight)
11. 1.000.000.000.000 (a billion)
12. 52 (fifty-two
13. -1.000.000 (minus a million)
14. 666 (six hundred sixty six)
15. 7.412 (seven thousand four hundred twelve)
16. 4 (four)
17. -326 (minus three hundred twenty-six)
18. 15 (fifteen)
19. 0 (zero)
20. 99 (ninety-nine)

Characteristics of whole numbers

The integers represent the most elementary tool of mathematical calculation. The simplest operations (such as addition and subtraction) can be done without problem with only the knowledge of the whole numbers, both positive and negative.

Also, any operation that involves whole numbers will result in a number that also belongs to that category. The same goes for the multiplication, but not so with the division: In fact, any division that involves both odd and even numbers (among many other possibilities) will necessarily result in a number that is not an integer.

The whole numbers have an infinite extension, both forward (on a line that shows the numbers, to the right, adding more and more digits each time) as backwards (to the left of that same number line, after passing through 0 and adding digits preceded by the sign "less".

Knowing the integers, one of the basic postulates of mathematics can be easily interpreted: ‘for any number, there will always be a greater number ', from which it follows that' for any number, there will always be infinite numbers greater'.

On the contrary, the same does not happen with another of the postulates that demands the understanding of the fractional numbers: 'Between any two numbers, there will always be a number'. It also follows from the latter that there will be infinities.

In terms of their form of written expression, whole numbers greater than a thousand are usually written by placing a period or leaving a fine space every three digits, starting from the right. This is different in the English language, where commas are used instead of points, reserving the points precisely for the numbers that include decimals (that is, those not integers).
