![]() ![]() After various manipulations and comparisons, I had two lists that I wanted to send to a client in an email so we could discuss them. Usually, these are serial numbers, but the lists I was dealing with yesterday were lists of apartment numbers in a high-rise building. Maybe you’ll find it useful, too.Īs I mentioned in a post last year, I often have deal with lists of alphanumeric strings. But when I had a problem yesterday, I came across a simple solution using the rs command, which I’d never heard of before. It would become positive.It’s not often that I run into a new (to me) Unix command. Opposite of negative two and then all of a sudden Negative in front of this, it would be the opposite of all of this. Take the opposite of two so that's just going to be negative two. Number line two to the left and this flips you back two to the right so all of this is going to be two but then you're going to Of the opposite of two, well that's just going to be two. Opposite of negative two, which is really the opposite Well, this part right over here the negative, the We could do something like what is the negative of the negative of negative- Let me do a different You a better appreciation for what opposite means and also how it relates to the actual negative symbol. Or we could just write positive three like that. So it's opposite is going toīe three to the right of zero. So what is the opposite of negative three? Well negative three is Opposite of negative- The opposite of negative three. ![]() So you can think about this as meaning this means the opposite. What would be the negative of negative three? And I encourage you to pause What would be the negative- Let me do this in another color. ![]() Of whatever this is, let's try something interesting. So with that in mind, if we literally view this negative symbol as meaning the opposite Or as a shorthand, we can just write- We can just write negative. We could literally write opposite, opposite of A is that number right over there. And so the opposite of A is going to be this value right over here. So if A is three tick marks to the right negative A is going to be Of these tick marks jump but let's say that A is some So let me draw a number line just so this can be a little bit, make a little bit more sense hopefully. And if this confuses youĪ little bit just look, A could be any number right over here. So if I said negative A, that means the opposite of the number A. If you were to say negative, instead of saying a specific number let's just say a letter thatĬould represent a number. So you can take this negative symbol as meaning opposite. Negative, let me write this, negative four. It, this is the number that is the opposite of four. So another way of thinking about it is, is that this negative Or another way to think about it, if you have a positive number, its opposite is going to be So its opposite is going to be one, two, three, four to the left. So if the number is four, what is its opposite? Well, four is one, two, three, four to the right of zero. This is just the symbol for number or shorthand for number. If you have a number and then we want to think about what the opposite of that number is. If we start with a positive number, say, the number four. We've already talked about what an opposite of a number is, but we'll review it a little bit. ![]()
