welcome you to my channel we

00:00:45

continue to study mathematics the topic of

00:00:48

today's lesson is integers in this

00:00:52

lesson we will continue to talk about numbers you and I

00:00:55

already know what numbers are called

00:00:58

natural numbers natural numbers are the numbers

00:01:01

that we use for counting for example

00:01:05

one two three four five six and so

00:01:11

on, the set of natural numbers

00:01:13

is written like this: if you

00:01:17

add negative numbers and 0 to the natural numbers,

00:01:21

you get integers. Now let's

00:01:25

write down the definition of integers. Integers

00:01:28

are an extended set of

00:01:32

natural numbers, obtained by adding

00:01:35

0 and negative numbers to it. The set of

00:01:39

integers is denoted by the capital letter z and the

00:01:45

set of integers is written like this: infinitely the

00:01:49

largest integer does not exist and the

00:01:51

smallest number does not

00:01:55

exist, but we can call

00:01:57

the largest negative number this is -1, we

00:02:02

can also call

00:02:04

the smallest positive number this is

00:02:07

one let's write down several numbers

00:02:11

and answer the question

00:02:12

whether these numbers belong to the set

00:02:15

integers minus 15 minus 100 40 21 542

00:02:26

pause the video and try to

00:02:30

answer this question yourself as we can

00:02:33

see all these numbers are integers,

00:02:36

which means they all belong to the

00:02:40

set of integers

00:02:42

you are probably asking the question which numbers do

00:02:46

not belong to the set of integers

00:02:50

integers do not belong,

00:02:52

for example, these numbers are

00:02:55

one whole six tenths 1 2 and the root of

00:03:00

2

00:03:01

all these numbers do not belong to the set of

00:03:04

integers these numbers are not integers

00:03:09

and we will talk about these numbers in

00:03:12

subsequent lessons the

00:03:15

set of integers consists of 3

00:03:18

parts the first of the set

00:03:21

positive integers are

00:03:23

written like this z and on top plus,

00:03:29

as we see, this is the same set of

00:03:31

natural numbers, just marked with a

00:03:34

different letter,

00:03:36

so we can write it like this, the second of the

00:03:40

set of negative integers

00:03:43

is written like this,

00:03:46

z only with a minus

00:03:50

and the third we still have 0 now

00:03:56

we denote all this using Euler circles,

00:03:59

as we see from the figure, the set of

00:04:02

integers consists of 3 parts, the

00:04:06

set of positive integers, the

00:04:09

set of negative integers and 0,

00:04:13

we also see that the set of integers

00:04:16

is above the set of

00:04:20

natural numbers, and the set of

00:04:22

natural numbers is a subset of the

00:04:25

set of integers numbers since all

00:04:29

the elements that belong to the set of

00:04:32

natural numbers also belong to the

00:04:34

set of integers

00:04:37

now let's denote the integers on the

00:04:41

number line

00:04:43
