Hail hail guys and then how are you everybody good everybody beautiful I hope so hey it's good people in today's class we're going to talk about equality yes guys that's exactly what you just heard we're going to talk about today's time right but good equality is the following o Before I leave for our overcome there I will ask as usual here on our channel for you to enjoy this class and subscribe to our channel so you don't miss absolutely anything in the world of education and doing this you help our channel to grow and produce
more quality content for you so well now here's the next thing I start this class asking the following question what is an equality ok the answer is ok and follow then let's see the definition to do with it here comes well what is an equality is a cent the theme between itself uses the equality symbol that is those two dashes in parallel in the right horizontal to represent a equality my God I didn't understand anything Calm down then read it again oh it's a mathematical sentence in which the equality symbol is used to represent an
equality right it makes it a little redundant right it seems like it explained almost nothing to me but I really don't have much to explain right so this is the definition of equality all right Ah now I understand something else that we can think of to help us understand a little more than the mother equality guys is the following just have to think of a mathematical sentence right and every time we find a right equality symbol, those two dashes here, horizontal parallels , we will have a certain equality. a look at some examples here if
And it's because it's the following guys often an equality we won't have an equality oh my god no don't keep lying to me this guy is he's trolling me it 's not possible calm down now that's exactly what you understood many times the math guy could be lying to us no he said look that it's an equality but it's not right so let's see some little liters here to see if in fact it's an equality right Here, good this month, the job we have here we have 2 + 5 + 7 equals a certain symbol
equals 10 plus four so here Theoretically it's an equality but I don't see if this equality is just right so ill go there go there good How to make the beads of this expression right get the green color here and let's go look at two plus five of the seven I'll put the 7 here and I'll copy another 7 but seven I'll put our little end the same and I'll add ten with + 4 = 14 beauty beauty and let's finish this equality don't finish the math we have to do and have to do here
we have to do seven plus seven and in the world where I live 7 + 7 = 14 so we'll put it here oh that 7 + 7 = 14 of these and Cup us in equal and put another 14 in handsome here right and good that whoever just proved that guys just proved that this equality is right guys because the following that 14 Theoretically = 14 it has to be a little entirely equal he himself right So this equality Okay our next example here guys is the following come with me here we have 3
x 3 right little equal sign an equality equals 6 plus one plus two right so let's make the bullet ball beads good three times three remember the multiplication table = 9 copy the equal sign and do what it does 6 + 16 + 1 = 7 right too good and copy two that we haven't used yet right let's finish copy 19 right just like equal sign and 7 + 2 = 9 so that comes here and puts it equals 9 So I just that we had here we had that what that 9 = 9 So
this equality is very correct And to finish now this sequence and give examples that the we worked out let's test more we have here what is it here there are two times five plus three little equals sign 3 x 3 + 4 will solve the beads and see if this equality is just right let's go so we have here, well in this case then the multiplication and a sum and we know how we are already that multiplication comes first so let's do it twice 5 = 10 copy the little train here talking about a little
bit here real quick real quick Okay it was good copy the very end 3 also the very end of the same and in this case here we have once again a multiplication and a sum let's do the multiplication 3 times 3 = 9 copy the plus sign with our beautiful comic And to finish what we do now make the beads that are there so 10 + 3 = 13 put it down here which is equal to 13 copy Nozinho of equal and 9 + 4 = as for nine ten eleven twelve thirteen = 13 so
I had it here too and put here 13 = 13 and good to do this here we saw that our equality is very correct ga read and good guys, as you may have noticed, it 's pretty gigantic here, look at this little word here, what I put as careful because be careful, right ? for you at the beginning that many times when something mathematical the exercise says that it is an equality many times it cannot be an equality, right, many times the city is wrong, right, that's what we have to be very attentive and attentive
there and be careful redoubled with that right and I 'm going to prove to you now here in some cases our equality is false right one oh our first one always here o we have a side 10 plus five with the three little sign equals equal to 19 let's see if it's ok ok then ok first 10 + 5 = 15 put it here 15 copied it by itself Too much Three equals sign and 19 ok and there was no need to do it here you can make it contain more than 15 + 3 =
as for 15 16 17 18 so people come here look et al hollow this here is equal to 18 right copied doesn't sell the same and copy 19 and look what we got here we got that 18 = 19 and go this is wrong right they are two different numbers they are numbers close to We all know this is but they are not the same guys in the world I live in 18 is different from 19 I'm sure your world is also right so 18 is different 19 is not the same So this equality here
oh it's wrong guys very wrong very wrong and well, how do we do that, right, to represent this is the different number, we're going to do the following, we're going to do the two little lines of the normal Equality, but we're going to draw a straight line here on the diagonal, indicating that what they are different so every time you find a symbol Zinho like this here the little equal sign a diagonal line is the different sign a different symbol so how do we law this is valid for the following o 18 is different and
19 there it is OK, okay? because 18 is different in 19 So this is our second example right here and let's see if the equality is correct or not I'm fine mom so oh 24 / 2 = Ah ok How to put 24 and 20 here by 2 = 12 copy the little sign of equal and good, do the multiplication Zinho on the other side that the following o 4 x 4 thinks about the multiplication table of 4 = 16 so if you have it here, put = 16 and well guys, there's no more content
to do right and Look, just take a good look at what we have it arrived we arrived that 12 = 16 more good there is something very wrong with that now that we know very properly that 12 is different from 16 is different right so this Zinho symbol here of equality it is wrong in fact we should have used one symbol of different that is this right here, the two little lines like that of Equality with a diagonal line and doing now guys our last always of this sequence of examples What we have here oh
come with me here come here we have the next only we have 16 / 8 adding + 1 = 15 - 14 Let's do it r the contained a good good between a division ones where it makes the first division 16 / 8 = 2 I'll put that has equal to two copy the little sign plus a little equal sign we do it now it's 15 - 14 on the other side ok it's equal to when 15 - 14 is equal to one then you have it here and put it here it's equal to one
in this perfect way and to finish it's just a matter of doing this extra amount and 2 + 1 = 3 so you have it here put it here is equal to three symbols going equal and copy one and good once again this equality is very wrong, right guys, what because he's saying here to people that 3 = 1 we know very well, right, it's clear This here that is wrong that it's false that 3 is different from one So na the truth we have that it was this here Then we would have to have
used the symbol of different right not this way here look there it is indicating that 3 is different from a beauty the butt guys is the following just to finish this super class of equality in the best way possible, one more little detail is missing that we have to undertake to undertake, cut for having failed yes good old man to close just super to the canvas there with a gold key there is one more thing you have to understand that it is the following oh let's fan oh bread pull a little that up right there
are two very important definitions that we have to get out of here knowing that it is the following ó let's go together ó first information the mathematical expression located to the left of the equals symbol is called first member Calm down there that we will understand better and the second information of the following ó the mathematical expression situated to the right of the equality symbol is called the second I didn't even understand this ending I didn't understand it was nothing so look I'm going to explain to you now that all it means is the following
we'll just get our equality symbol right there we're going to do with it until we do the following we're going to say that everything to the left of the equals symbol we're going to call it the first half, then repeating everything to the left of d our equality symbol we will call it the first member remember keep it there in the cachola in sure that good and everything that has to the right of our equality symbol we will call the second member ok always always always her so let's just see some simple ones to make
it a little clearer right so let's go up here to Pampa. Well, here we have three equalities right we have this equality Zinha this equality And this other equality here and well let's change the color and now I wanted to do it now we're going to see what it actually was Hi people read Look at that in this equality symbol, everything that is to the left of the equality symbol so not, for example, equality we look to our left and we have 3 + 2 to the cube . a member first member this way here
right and good looking at equality again and looking to the right everything that is to the right of our equality symbol right all this expression here look we're going to call the second member right that's really good, right, this definition It's very quiet, just remember that left first member and right second Sunday, sweetie who are doing two more jobs here goes to finish our super class in this equality here what the ge We're looking at the equality symbol on the left, right All this expression here we're going to call it the first member once again
and that's always guys always always always always going to be the same thing so this one is the first member looking to the right this expression that we'll call a second member right second Sunday that's always right There's I don't know that was it you can do whenever you want left first member right second Sunday always and to finish here we're going to do more and clean without equality everything that is left we are called the first member because here is the first member is Ah and everything that is on the right all this here
oh gigantic suspension we will call it the second I remember it this way here guys very calm very good right and good Vera with that here we end this room for today, i hope everything is understood that you have understood to the fullest everything that has been said here is that, thank you very much for your attention there and good studies
