00:00:04

hi my name is gesca and I

00:00:08

welcome you to this mine and

00:00:09

rick hughes are the priority of

00:00:11

operations

00:00:13

located in fifth or sixth year

00:00:15

it's maybe a minute the team who

00:00:18

vote interested

00:00:19

we are going to do a complete review of the

00:00:22

priority of operations follow a

00:00:24

simple one

00:00:26

we will first see the definition of a

00:00:28

priority so what is a priority

00:00:32

then we want to see the four steps

00:00:34

the priority of operations using an

00:00:36

example

00:00:39

continue with two other examples to

00:00:41

practice

00:00:44

so what is that the priority

00:00:47

to explain it to you I studied an

00:00:49

example completely different from an

00:00:51

example mathematics have redone

00:00:53

gather a cake

00:00:56

to make a cake I have to follow an

00:00:59

order I have to follow a priority

00:01:03

lord to respect it is first to prepare

00:01:06

the mixture for the cake

00:01:09

then these two lighthouses heart the cake

00:01:13

and finally

00:01:15

to decorate it

00:01:17

before continuing my explanations

00:01:19

I have a question for you it is a

00:01:21

first question of a series of

00:01:22

questions that will be there throughout

00:01:24

the mine and rigor

00:01:26

these questions will allow me to

00:01:28

remain active and to think even if

00:01:31

it is me who explains to you what is the

00:01:33

priority

00:01:36

arma first breakages years is a real or

00:01:37

false

00:01:40

it is possible to change the order of the

00:01:43

steps of preparing a cake

00:01:49

it is false

00:01:52

and no it is not possible to change

00:01:54

the order of preparing a cake we will

00:01:56

try to see if

00:01:58

I try

00:02:00

to decorate my cake

00:02:03

before baking it

00:02:05

I think that the expected result will

00:02:10

not really be the result

00:02:11

the result that we will see will not

00:02:14

really be like the result that was

00:02:15

expected 1.6 g the decoration before having

00:02:18

killed it that risk of not being really great

00:02:22

then it proves that it is absolutely necessary to

00:02:25

respect the order of priority when

00:02:28

making a cake

00:02:30

why am I explaining all this to you because

00:02:33

it is exactly the same thing with the

00:02:34

priority of operations in a chain

00:02:36

of mathematical operations

00:02:38

the steps so the priorities are

00:02:42

really important it is absolutely necessary to

00:02:44

respect them otherwise the result will not be

00:02:47

what expected

00:02:52

together with a first example

00:02:55

because if we continue to talk about

00:02:56

cakes this is what I will

00:02:58

want to eat

00:02:59

we are ready to do the first example

00:03:02

with 7.5 of operation

00:03:05

what is a chain of operation in

00:03:08

fact it is several operations put

00:03:10

together in a chain so we see here that there

00:03:13

is a subtraction a notification there

00:03:16

will be an addition a division and

00:03:19

only one result in the end

00:03:21

that is the chain of operations that we

00:03:24

must solve and to get there we must

00:03:26

respect the priority of the operations

00:03:30

the first step is hungry and c

00:03:34

m

00:03:36

so I must find in the chain

00:03:38

d 'operation the parentheses and resolve

00:03:42

an operation which inside the

00:03:43

parents pact so in this example

00:03:46

the operation which inside the

00:03:48

parentheses its 6 / 3 I will start

00:03:52

with ray zone

00:03:55

this operation on

00:04:01

16 / 3

00:04:04

anddiallo

00:04:06

I will straight away rewrite machand

00:04:08

operations by replacing the parentheses

00:04:11

and the operation inside the

00:04:14

parentheses

00:04:16

the result of the division so I will

00:04:19

rewrite the whole string

00:04:22

three exponents 3

00:04:24

- this

00:04:27

wow 2 because I replace if divided

00:04:31

by three with its result which is two

00:04:35

so that

00:04:37

'' I did by four

00:04:41

and the expected results

00:04:44

so I'm going to look now if I have

00:04:46

other parentheses to make in my

00:04:48

chain of operation

00:04:51

I don't have any other tarentaise so I

00:04:53

can pass

00:04:54

next step to the east usually on

00:04:57

the other hand I

00:04:58

explained it to help me better

00:05:00

explain the next step I am going to

00:05:02

erase the calculations that I made on the

00:05:04

board I am going to have the scene

00:05:08

of operations rewritten properly

00:05:10

the second step is to find the

00:05:13

exponents in the chain of operations

00:05:16

in this chain of operations these gels

00:05:19

exponents 3 I'm going to have to find the

00:05:22

power of exponential notation 3

00:05:27

exponent 3

00:05:28

if you remember correctly what you have to

00:05:31

do with an exponent is to

00:05:34

multiply the number the number of times

00:05:37

given by the example so in this case if

00:05:40

I have to multiply the number three times

00:05:44

three fingers in do 3

00:05:48

or 3

00:05:49

hu to 3

00:05:51

find its result which is the

00:05:53

power of exponential notation

00:05:56

then j 'go 3 x 3

00:06:00

and keep 9

00:06:02

9 x 3

00:06:06

equals 27

00:06:08

in visual top

00:06:10

is therefore 27

00:06:12

then as earlier game came to rewrite

00:06:14

the chain of operations by replacing the

00:06:16

exponential notation by its power

00:06:20

I replace three exponents 3 by 27

00:06:27

27 - 10

00:06:29

to 2

00:06:32

flounder this don roose

00:06:35

it is by case

00:06:38

and the expected response

00:06:40

so once again I check it if

00:06:43

I have other exponents in the chain

00:06:46

of operations in this case I do not have

00:06:49

any other then I can go to

00:06:51

step 3 I'm going to erase again what

00:06:55

I did on the board and come back with

00:06:57

the operation rewritten more

00:07:00

neatly for the next step

00:07:02

step 3 is to find the

00:07:05

multiplications and divisions and

00:07:08

solve them in the other case occurs

00:07:09

in the chain of operations, that is to

00:07:11

say from left to right we will

00:07:14

look in the example

00:07:16

in the example here I start from the left

00:07:18

of the beginning of the chain of operations and that

00:07:21

I go to the right I

00:07:23

first encounter a multiplication so I will

00:07:27

first solve the modification 10

00:07:30

pado

00:07:31

10 x 2 gives twenty then I will

00:07:35

rewrite the chain of operations right

00:07:37

away replacing ten times on the other

00:07:40

hand the answer 20

00:07:42

27

00:07:45

- yes

00:07:47

the sns

00:07:50

it is the case by case

00:07:52

of the guys to the expected answer

00:07:55

I check if there are no other

00:07:57

multiplication division in the

00:07:59

operation chain then I look but it is

00:08:01

a subtraction the addition and I have a

00:08:04

diffusion

00:08:06

so I will now solve the

00:08:08

remaining division which is dose / 4 and

00:08:12

12 / 4 kim dong 3 so I will rewrite

00:08:17

the chain of operations to change bone

00:08:18

divided by three and by four by its

00:08:21

answer 3

00:08:23

27 -

00:08:27

this3

00:08:29

and calm to the expected results

00:08:32

to be sure that I have not

00:08:34

forgotten any I will check once again

00:08:36

if I have multiplications or

00:08:38

divisions in the chain of operations

00:08:40

respect so I have a subtraction one

00:08:44

addition I no longer have multiplication

00:08:47

of the two divisions so I can move on

00:08:49

to step 4

00:08:51

we are at the last step the

00:08:54

priority of operations which is the

00:08:55

fourth step it looks a lot like

00:08:58

the third step because these two

00:09:00

networks in the additions and

00:09:02

subtractions in the order they

00:09:04

will be presented in the

00:09:05

operating room so from left to

00:09:08

right

00:09:09

I have a question for you

00:09:13

in this example the addition or

00:09:17

subtraction should be done

00:09:19

first so we do not sing it ration 27 -

00:09:24

23

00:09:27

and we wonder if it is the addition or

00:09:29

the subtraction

00:09:31

which must be done in pro

00:09:35

this pays the subtraction which must be

00:09:37

done first

00:09:40

yes because when I look from

00:09:42

the start of mach and operations so from

00:09:44

left to right

00:09:46

this is the subtraction that I will

00:09:48

encounter first

00:09:50

so the subtraction that I will do

00:09:52

is 27 - ivry which gives this so I

00:09:56

will rewrite machand operation 7

00:09:59

plus

00:10:01

3 this is important to rewrite the chain

00:10:04

of operations even if it becomes

00:10:06

smaller and smaller because one

00:10:09

could say but I don't really feel

00:10:11

the need to write it but I say it's

00:10:13

really important to rewrite it to

00:10:15

be sure of wrong positions in the

00:10:17

priority of operations and it allows us to

00:10:19

keep control and focus on the

00:10:22

calculations that fire then this +3 is

00:10:26

the last addition that I have to do 4

00:10:29

I go there resonates so 7 + 3 is equal to

00:10:32

10 d I found the result of this plus

00:10:36

three but I also found the result

00:10:38

of the complete chain of operations so

00:10:42

we saw together a first example to

00:10:44

present to you the four operations the

00:10:47

four operation priorities because I

00:10:50

look at the whole process that I did

00:10:51

to arrive at my final result I

00:10:54

see that I started from a chain

00:10:56

of operations which were very long

00:10:57

and whined smaller and smaller to

00:11:01

arrive at my last result

00:11:04

that

00:11:07

is the form of a funnel

00:11:13

because this

00:11:15

shining network of operations is important to

00:11:18

see at the end that we are starting from a

00:11:21

larger chain of operations towards a

00:11:23

smaller one so to see a little bit of this funnel

00:11:27

in your approach is a good clue

00:11:31

which tells you that everything is going well then

00:11:34

that you are going to we final result

00:11:37

we are going to keep together from

00:11:40

these what were the four steps

00:11:42

that we did together

00:11:46

start by doing

00:11:47

[Music]

00:11:49

the parents press

00:11:59

then

00:12:02

we did the exponents

00:12:09

we continued with the medications the

00:12:12

divisions

00:12:22

the two were in step 3

00:12:26

and we finished

00:12:28

with step 4 for the editions

00:12:34

and subtractions

00:12:40

if I take the first letter of

00:12:43

each word that I so just wrote the

00:12:46

same the die the a and the e s

00:12:50

I get the acronym windows

00:13:00

which is an acronym that I can use

00:13:02

to remember the order the priority

00:13:06

of operations so the package for

00:13:08

parentheses the e for exponents the m

00:13:11

for modification the deposit division the to

00:13:15

your actions and the s for subtraction the

00:13:19

next example that we are going to do together

00:13:20

I am going to use the acronym during this

00:13:23

to show that when we use there

00:13:26

it is easy to remember the

00:13:28

priority operations

00:13:30

we are now ready to do a

00:13:32

second example and this second example

00:13:35

I will do with the acronym penda which is

00:13:38

worth helping me to remember the order

00:13:40

of the priority of the operations to follow

00:13:42

the first step can be represented

00:13:45

by the letter p which is in fact the

00:13:49

first letter of the name parenthesis because

00:13:52

the first step is the parents

00:13:55

you have so in the chain of operations

00:13:57

I found it the elderly parents of the

00:13:59

parenthesis here I have to resolve

00:14:02

the operation even if 'inside

00:14:04

this

00:14:05

the operation

00:14:07

12 - five

00:14:09

doses minus 5 and wales this then I

00:14:12

will rewrite the chain of operations

00:14:15

replacing the subtraction with its

00:14:18

answer which is

00:14:23

the set is right here so I replace

00:14:27

dawes at least 5 per set

00:14:29

I check if there are no other

00:14:32

parents passing through the new operation chain

00:14:37

I have no water parentheses so I

00:14:39

can go to step 2

00:14:42

abdou which is represented by

00:14:45

the letter e of antenna ars and which is

00:14:49

the first letter of the exposed word

00:14:53

so the second step is to find

00:14:56

the exponents

00:14:57

and find the power of the

00:14:59

exponential notations which are in the operations chamber

00:15:03

here I have the exponent 4 so I have to

00:15:07

find the power of two exponents 4

00:15:11

and as we saw earlier two exponents

00:15:14

4 means that I am going to multiply

00:15:18

four times the number of parliaments

00:15:21

ok

00:15:23

two times two ways 2

00:15:27

x 2

00:15:31

2 x 2

00:15:33

4

00:15:35

4 x 2.8

00:15:38

and

00:15:39

eight times two meanings

00:15:41

the result of my multiplication

00:15:45

and it is also the powerful of the

00:15:49

exponential notation 2 exposes investigation

00:15:52

so I will come and replace two

00:15:54

exponents 4

00:15:55

with the result which is 16

00:16:00

in

00:16:01

here I replaced two exponents 4 with

00:16:03

this and I have my new chain

00:16:05

of operation

00:16:07

I no longer have

00:16:09

any exponents in my operation chain

00:16:11

so I can move on to the next step

00:16:14

I have reached the third step which

00:16:17

had been presented by the letters m e and b

00:16:20

in the acronym tenda the m which

00:16:23

represents multiplication and the two

00:16:26

divisions

00:16:28

so the third step is to find

00:16:31

the modifications and the divisions in

00:16:33

the chain of operations and to

00:16:34

solve them in the other that it

00:16:35

presents itself from left to right

00:16:39

in my chain of operation I'm going to

00:16:42

go to the left and I'm going to look at

00:16:44

the first division multiplication that

00:16:46

I come across. I already have from the start of

00:16:50

match and operations a division also

00:16:52

g20 divided

00:16:55

by

00:16:56

120 1 / which by 5 gives me four so

00:17:00

I'm going to rewrite straight away the chain

00:17:01

of operations once again to be

00:17:04

sure not to make a mistake in the

00:17:06

rest of my room and I will write

00:17:09

4 which replaces points of the department

00:17:13

I continue I will continue to

00:17:16

check in my chain of operations

00:17:17

if there is other modifications to the

00:17:18

divisions

00:17:19

here I have an addition gene called

00:17:22

suppressor here I like division so I

00:17:24

do

00:17:26

7 / 7 7 / 7 also I will replace

00:17:32

the division not the answer which is

00:17:36

just to be certain I will

00:17:38

check again

00:17:40

j I have an addition

00:17:42

a subtraction I no longer have

00:17:44

multiplication or divisions so I

00:17:47

can move on to step

00:17:49

4

00:17:51

the case step that they represent by the

00:17:53

letters a and s

00:17:55

the first the help of an addition and s

00:17:58

which is the first letter of the world

00:17:59

subtraction the fourth step which is

00:18:02

the last and so find the

00:18:05

additions and subtractions and

00:18:06

solve them in the order it

00:18:07

comes from left to right

00:18:10

then the first addition I find

00:18:13

these case

00:18:15

the size at

00:18:17

4.16 which is equal to bree so I am going to

00:18:20

replace 4 the cese by 20

00:18:23

gesture knows and I have only one subtraction left

00:18:29

20 - 1 which is equal to

00:18:34

6 9

00:18:37

so I am a little off there

00:18:41

I am going write it down

00:18:43

and see note funnel

00:18:47

when we look at the entire

00:18:51

process that we have done there we can clearly

00:18:53

see as I said earlier there we obtain

00:18:55

up

00:18:58

nantes au noir like this here which shows

00:19:00

that we are starting from a

00:19:03

very long operation chain and we will always reduce

00:19:07

the operation chain for referees to a

00:19:08

single result in the end

00:19:10

then we are at the last example of

00:19:14

the mini recovery we will resolve this

00:19:16

chain of operations at this next moment

00:19:18

again once the four steps the

00:19:20

priority of operations the first

00:19:22

step

00:19:25

the parentheses

00:19:27

in my chain of operation this trip and

00:19:29

parentheses then I will solve

00:19:32

what is inside 4 x 2 which gives

00:19:35

8 I will replace 4 x 2 in my

00:19:38

operation chain or rewrite the

00:19:40

operation chain by replacing 4 x 2 with

00:19:42

huth

00:19:44

as I no longer have parenthesis I will

00:19:47

go to the second step

00:19:49

expose them

00:19:51

in the operation chain I have no

00:19:53

exponents it is something that

00:19:54

could happen to you too with

00:19:57

certain chains of operations not

00:20:00

having a step to do means that we

00:20:03

simply have to move on to the next step

00:20:05

so I am going to move on to the stage of

00:20:08

modifications and divisions

00:20:11

in my chain operation I see that

00:20:13

I have a multiplication this time in

00:20:17

us which they give me 77

00:20:20

I replaced this time 11 passes for

00:20:22

117

00:20:24

and then I look if there are other

00:20:27

multiplication division I don't have any

00:20:29

so I pass my edition

00:20:32

eo subtraction

00:20:34

the first subtraction that I

00:20:37

encounter

00:20:39

is 8 - 3 8 months and 3 kingdom 5 kr

00:20:45

I replaced 8 - 3 by 5

00:20:48

then I obtain the last operation

00:20:50

that jory has to solve to get the

00:20:53

result of the chain of operations and

00:20:55

five + 77 e

00:21:02

then gives the result of the entire chain of

00:21:04

operations and 90

00:21:08

we have completed the mini recovery so we have

00:21:10

finished seeing all together what we

00:21:14

had to see we have reviewed the four steps

00:21:19

to follow to the priority of operations

00:21:20

that we can remember with the word penda

00:21:24

which is a good word for

00:21:27

a district there to remember the

00:21:29

four steps and the order

00:21:32

and if I can give another piece of

00:21:34

advice it would be to be

00:21:36

careful well you reason chain

00:21:38

of operations to pay attention to

00:21:39

each of the operations or to check

00:21:42

your calculations you must also take

00:21:45

your time to rewrite the

00:21:48

operating chambers in each operation

00:21:50

because if you make a mistake during your approach

00:21:53

it is certain that your take in the end this

00:21:56

meal is good

00:21:57

so I wish you good luck then

00:22:00

well we'll see you again maybe in another

00:22:01

mini pick up by

00:22:05
