### Examples: 0, 7,212 and 1023 are all whole numbers

(But numbers like ½, 1.1 and −5 are not whole numbers.)

## Counting Numbers

Counting Numbers are Whole Numbers, but without the zero. Because you can"t "count" zero.Quý khách hàng sẽ xem: Whole number là gì So they are 1, 2, 3, 4, 5, ...

## Integers

Integers are lượt thích whole numbers, but they also include negative numbers ... but still no fractions allowed! So, integers can be negative sầu −1, −2,−3, −4, ... , positive sầu 1, 2, 3, 4, ... , or zero 0

We can put that all together lượt thích this:

Integers = ..., −4, −3, −2, −1, 0, 1, 2, 3, 4, ...

### Examples: −16, −3, 0, 1 and 198 are all integers.Xem thêm: Khái Niệm Các Khoản Giảm Trừ Doanh Thu Là Gì, Các Khoản Giảm Trừ Doanh Thu

(But numbers lượt thích ½, 1.1 & 3.5 are not integers)

These are all integers (cliông xã to mark), và they continue left & right infinitely:

## Some People Have sầu Different Definitions!

Some people (not me) say that whole numbers can also be negative sầu, which makes them exactly the same as integers.

And some people say that zero is NOT a whole number. So there you go, not everyone agrees on a simple thing!

## My Standard

I usually stiông chồng khổng lồ this:

NameNumbersExamplesWhole Numbers 0, 1, 2, 3, 4, ... 0, 27,398, 2345 Counting Numbers 1, 2, 3, 4, ... 1, 18, 27, 2061 Integers ... −4, −3, −2, −1, 0, 1, 2, 3, 4, ... −15, 0, 27, 1102

And everyone agrees on the definition of an integer, so when in doubt say "integer".

And when you only want positive sầu integers, say "positive sầu integers". It is not only accurate, it makes you sound intelligent. Like this (note: zero isn"t positive sầu or negative):

Integers = ..., −4, −3, −2, −1, 0, 1, 2, 3, 4, ... Negative sầu Integers = ..., −4, −3, −2, −1 Positive Integers = 1, 2, 3, 4, ... Non-Negative sầu Integers = 0, 1, 2, 3, 4, ... (includes zero, see?)
