      271

Examples: 0, 7, 212 và 1023 are all whole numbers

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


Counting Numbers

Counting Numbers are Whole Numbers, but without the zero. Because you can"t "count" zero.

So they are 1, 2, 3, 4, 5, ... (& so on).

Natural Numbers

"Natural Numbers" can mean either "Counting Numbers" 1, 2, 3, ..., or "Whole Numbers" 0, 1, 2, 3, ..., depending on the subject.

Integers

Integers are like whole numbers, but they also include negative numbers ... but still no fractions allowed!

*

So, integers can be negative −1, −2,−3, −4, ... , positive sầu 1, 2, 3, 4, ... , or zero 0

We can put that all together like this:

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


Examples: −16, −3, 0, 1 và 198 are all integers.

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


These are all integers (click khổng lồ mark), & they continue left và 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 xã khổng lồ this:


Name
Numbers
Examples
Whole 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 Integers = 0, 1, 2, 3, 4, ... (includes zero, see?)
