# Word union symbol - viable solutions

## How do you add Union and intersection symbol in Word?

Click the Math option and hunt for the **symbol**. Highlight and click **Insert** to place it in Text Edit. Once you **insert** the **symbols**, you have to make sure your encoding is set to UTF-8 during the save process.

Hi, this is Gary from MacMost.com.

Let me show you how to find and type hidden special characters on your Mac keyboard. MacMost is brought to you thanks to a great group of supporters. You can read more here as well find out how to join and get exclusive content.

You probably already know that you can enter almost any special character or emoji by holding down the Ctrl + Command keys and pressing the spacebar. Then you get this viewer here and you can browse it and look for things. Also, if you want to type accented characters or character changes, you can press the key on your keyboard e.g.

For example, press and hold the e key and then you get different versions of that key, so you can type é with an accented character for example, but there are some characters that some people use a lot and you may not want to go to the emoji viewer every time you want to use it, suppose you want to type in degrees, you can type that in pretty easily and I'll show you how. You can also type things like the Apple icon. So instead of giving you a huge list of keyboard shortcuts to type in all of these different characters, I'm going to show you how to find these on your own.

The first step is to go to the Apple menu and select System Preferences, go to Keyboard in System Preferences, then under the Keyboard heading, select Show Keyboard and Emoji Viewer in the menu bar. When I do this, you'll see an icon in the top right corner, I'll click it and I'll see it appear. Now it appears sometimes as a symbol like this, and sometimes as a flag.

It depends on if you have multiple keyboards here, although sometimes it will show up as a flag anyway at the top as the flag of the current keyboard you are using, but either way you get the same thing, clicking on it here will give you that option to go to Show the keyboard display, I'll choose this, now I get this little keyboard here, as I type you actually see the keys being pressed. What's even better is that you can hold down the odifier key, like the Shift key, and the keyboard will change, showing you what characters you get when you type a key. So note the 1, 2 and 3 keys for example.

If I hold down the Shift key and I do this on the real keyboard, you will see that I get an exclamation point, @ symbol, and the pound sign # on my keyboard. If you are using a different keyboard, say British keyboard or Spanish keyboard, then you will see different things here. I can also press and hold the Shift key here on the screen.

In fact, you can even type here. It gets interesting now when you go to the Option key that's right here; I'll hold it down on my actual physical keyboard and see these characters change. A number of special characters are now displayed.

For example, I can see the pi symbol here, when I release the Option key I can see that this is the p key. Hold it down i see it's pi. So now if I want to type in the pi symbol I know I can do that with option p and I get pi you can hold down the option key and look through these characters to see if you are using anything all the time.

For example, if you use the copyright symbol a lot, it might be useful to know that Optiong is the copyright symbol. Option r is registered. There are many mathematical symbols here too.

Not only can you see these here, but if you hold the Option key and hold the Shift key, you'll see various characters, including the Apple icon. Toggle option K is the Apple symbol. Toggle option 8 is the degree symbol.

Holding the Option key changes the zero to what looks like the degree symbol, but I think this is mostly used when you want to represent a dollar amount, but want the zeros to be raised like $ 8, eight zero zero. Also notice that some of these buttons are orange. This means you can use that key and then type a letter.

For example, here is an accent mark. It's option e.If I type option you can see the accent mark appear but it has this hello ghlightedbackground, now if I type a letter like e you can see the e is placed under the accent mark.

I can do the same thing, option e, and then type i and you can see the accented character is placed above the i are alternative ways of typing accented characters. I think today it's easier to just hold the button and choose what you want. But this method is actually older than this, so people can get used to using these characters that doesn't mean the fonts you are using are actually in the font group.

For example, special fonts might not have the Apple symbol, they might not have the math symbols, many of these things might be missing and just stick with the standard letters. But for the most part, you can mix and match fonts. So if you need to include the Apple symbol and the font you are using doesn't have it, you can just switch to a standard font like Helvetica one character to get the Apple symbol there.

## How do I type nCr in Word?

**Type nCr**.- Highlight 'n', press "Ctrl + Shift + +" or the 'superscript' button (the place with the bold, italic and underline)
- Highlight 'r', press "Ctrl + =" or 'subscript'

Hello and welcome to another edition of hackingmaths.

In today's lesson, you will learn how to write a formula using the Formula Editor in Microsoft Word. This method works in Word 2007 or later. I loaded Word and on the right I have the formula for calculating the standard deviation of x.

Now I will not go into how to use the formula that is covered in another lesson. Today I'm just going to show you how to write the equation in Word. So the layout of Word changes slightly depending on the operating system.

To find the Equation Editor, go to: Document Items on the Mac, then go right until you find Equation. On the PC, the only difference is that you click Insert, then go right until you find Equation and look for the Greek letter Pi. Ok, let's start writing the formula in Word.

I look at my equation and see an S with a diminished X, that X is in something that has been subscripted. So let's start writing our formula in Word. I'm clicking Document Items because I'm on a Mac.

I'll scroll right and click on equation. I get this blue box that shows up here. Now I want to enter the S with the X as an index.

I need to find the icon that says script and click on it. And it gives me different options. I have to choose the second one.

This gives me a box and a bottom box. When I click on it in the first box, I type S and in the lower box I type X. Now I have to insert an equals sign.

I just entered it right away, it would be in the index. What I really need to do is just press the right arrow key. And then immediately press.

Take a moment and look at the formula. Next is a square root sign. Everything is included in it.

So let's put one of these aside. You can find this by clicking on the Radical icon. Click on that.

And select the first one. We now have the square root with a dotted box in it, in the dotted box we are going to write the rest of the equation. Click the dotted box.

The next thing we see is a break. Click the fraction icon and select the first one. Now press the minus key and then the letter X.

We have now created the main part of the equation. Let's finish it. Click the dotted box above the fraction.

Then click on the operator icon and select the first one. This will insert the sum symbol into the equation. Now click on the box next to it.

Squares are set from the Script family, so select the Script icon and choose the first one. In the upper part of the fraction we have to click on the large dotted field and enter the X. Then click on the little dotted box above and type the number 2, which is the top of the faction covered.

Now let's get down to the bottom, click the dotted box and type the letter n, just two more things to do and we're done. Look at our formula, we see that the X is squared at the end but also has a line across it. Highlight the X by left clicking and dragging, it should turn blue like mine.

Click on the accent icon and find the one with the line above it and select the bar. Highlight the X again by clicking and dragging the left mouse button again. Notice how the highlighting looks like on me.

You'll need to replicate this before taking the next step. Now select the script icon and select the first one. And enter the number 2 in the small field.

Well done, you have written your first equation in Word. That's all for this lesson. I'll see you next time at Hackingmaths.

## What is the union sign?

The **union symbol** ( ) denotes the **union** of two set s. It is commonly used in mathematics and engineering. Given two sets A and B, the **union** of A and B, written A B, is the set C of all elements that are in A or in B.

This article is about notation and I'm going to describe the most common notations we use to talk about sex.

For our purposes, we think of a set as a collection of things and numbers, usually they put an asterisk here because if you ask a logician they will tell you this is a terrible way to think about assets , and it causes trouble, and they're right, but for our purposes it's fine, it works, and it's simple, so let's leave it at that, so let's think of a set as a collection of things, and those things are the elements of the set here is an example I will describe oneset when I write it like this I gave this set a name here This is the name of the set and then I am using curly braces here to describe the set between the curly brackets describe I am describing for example in this case this is a set that has three elements and the elements are the number four, the number five and the number six sex over sex, so let's introduce them first nThese two symbols are used to say that something is an element of a set or that something is not an element of a set. For example I'm going to talk about these three sets, a B and C and then I could say that is an element of abut one is not an element of B okay so these two symbols are correct relationship between an element and a set this symbol is differentThis symbol describes the relationship between two different sets and it means that it is a subset of them, instead of saying if an element is in a set let's say I am comparing two sets and want to see if one contains the other, for example with this one Case I can say that Ci is a subset of a, i.e.

it is contained in a, and unfortunately I have to pause here and give a warning, because this notation comes with a little difficulty, it is not entirely universal and that's why I have this symbol this Symbol used here to mean that something can be a subset of and possibly equal, hence the small second layer of bars that mulates an equal sign, whom n i ever want to say that something is a subset of and i want to state but they are not equal then i write this so that this symbol means that the smaller subset is strictly less than or equal and this means that they are strictly less is, but unfortunately some books do things differently and some books use this symbol to indicate that it is a subset and may be the same. Then if you want to indicate that it may not be the same, use a different symbol, for example this one, but this is a problem as it can mean two different things depending on who writes it. My personal preference is always to use a small symbol or this symbol and then no ambiguity is possible.

Let's go back to all the notation parts these two symbols are used to describe operations between sets the first means union of sets for example if I write a union B it means I 'I will construct a new set and the elements of this new set everything, what was already in either a or in B or possibly in both, so for example in this case I take all elements in a or B or in both and this could be this set and this symbol means intersection of sets, so it is also used to construct a new set that is given and in this case I'll take all the elements that are in both set a and B, so in this case there could be a set with a single element that is two. After all, this symbol is used to mean the empty set and that is simply the set with no elements, so one could describe it differently, the empty set is that set and after all, there is nothing there are a few sets of numbers that matter because they are often pappar and it is convenient to have names for them so that we can refer to them are numbers that we will not talk about, that we have a special name for and that are universal. Everyone agrees with this name, there are capital letters with an additional bond M, this M stands for the natural numbers, these are the numbers, this is the first sentence you learn in kindergarten and that comes with a career that I studied here from scratch, but that's also a matter of convention Some books start from zero Some books start one There are good arguments for both, we disagree on the second symbol that represents the integers numbers that are both positive and negative Q represents the rational that the fractions are everything that can be written as the quotient of whole numbers and finally R stands for the real numbers these are everything that has a decimal expansion sonotic that these are subsets of each other, each is greater than the next
