- What ns wantto perform in this video clip is think around what it means tohave an the contrary of a number. Allow me attract a number line here. Let's draw a number line. And also let's placed some numberson this number line. We deserve to start in ~ zero, and also if us go to the rightwe have positive numbers. One, two, three, four, five. Together we go to the left weget more and an ext negative. So an unfavorable one, negativetwo, negative three, an unfavorable four, and I cankeep walking on and on and also on. Let's pick one of these numbers. Let's say the we pick the number three. What is walk to be theopposite that the number three? well the opposite of thenumber is a number that's the very same distance fromzero but on the various other side. So three is 3 to the ideal of zero. One, two, three. So its the contrary is walking tobe 3 to the left of zero. One, two, three. Therefore the the opposite ofthree is negative three. Let me do a small table here. If we have actually the number, the number. And then we have actually its opposite. We have actually its opposite. So us just identified thatif you have the number three, its opposite is goingto be negative three. Now what if your number is negative? What if your number, let'ssay the number an adverse four. What's the opposite of that? and I encourage friend to pause the video clip and try to think around it on your own. Well, you say, okay, negativefour is best over here. That's an unfavorable four. That is four to the left of zero. One, two, three, 4 to the left that zero. So its opposite is going tobe four to the appropriate of it. So one, two, three, four. It's walking to be positive. It's going to be optimistic four. Therefore you're probably startingto see a sample here. The opposite of a number is walk to it is in the opposite sign of that number. If you have actually a confident three here, its opposite is goingto be an adverse three. If you start with negative four, its the opposite is going come be hopeful four. One method to think aboutit, it's walking to have the very same absolute worth buthave a various sign. Or another means to think about it is, but if this is threeto the appropriate of zero, its opposite is going to bethree come the left of zero. Or if the number is fourto the left of zero, its the contrary is going come befour come the ideal of zero. So we'll do one last one. What is opposing of... What's walking to be the the contrary of one? well one is one come the right of zero, for this reason its the contrary is going tobe one come the left of zero, or an unfavorable one. Or another way to thinkabout it, one is optimistic so its opposite is wherein you'regoing to change the sign. Instead of being positiveit's going to be negative. It's going come be an unfavorable one. Either method that you can think about it.
