How to write a square root on the keyboard. Square root. The Comprehensive Guide (2019)

Adding special characters through the “Insert Symbol” menu.

Select menu items sequentially Insert-Symbol... A sign with a set of available symbols will appear on the screen. Select the desired symbol and press the button "Insert". The corresponding symbol will appear in the text at the cursor position. To speed up the search for the desired symbol, enter in the field "kit": "mathematical symbols". To display full list characters in the “from” field must be set "Unicode (hex)".

Selecting the desired character can be significantly speeded up if its code is known - there is a special field for entering the character code: "Sign code". For example, for the square root (√) it would be "221A"(“A” is Latin, case is not important).

It is more convenient to re-enter characters through a special panel "Previously used symbols". Here, for frequently used characters, you can configure autocorrect parameters or hotkey combinations. The set of characters also depends on the selected font (the “Font” field). There is a special tab for entering some characters - "Special signs".

Quickly enter characters using the Alt + Character code combination.

The fastest way to print special character, the image of which is not on the keyboard, can be done using a combination of the Alt key and the character code. The Alt button is pressed and held while the character code is typed on the numeric part of the keyboard. For example, for the square root, the combination Alt 251 is used. Thus, when publishing content, all that remains is to control free space on a server dedicated to your site, using an extension like php-snmp.

Inserting mathematical symbols using the formula editor.

Complex mathematical symbols and their combinations (formulas) can be inserted using the built-in formula editor in Word. Select menu items sequentially: Insert – Object – Microsoft Equation 3.0. The mathematical formula editor will open, in which you can type almost any expression.

If the line "Microsoft Equation 3.0" does not appear in the drop-down menu, which means you need to install it. To do this, take the installation disk with Word and run the installer. Check the boxes for those items that need to be “additionally installed”. After installation Microsoft Equation 3.0 the corresponding line will appear in the drop-down list.

Alternative ways to create mathematical formulas.

You can type a mathematical formula (in particular, any mathematical symbol) in Word by selecting sequentially: Insert – Field – Formula – Eq. This method is practically no different from the previous one, since in the end the same mathematical formula editor opens.

In addition to the “visual” formula editor, Word also has a “text” expression editor. To launch it you need to press the key combination Ctrl+F9(F9 while pressing CTRL). Inside the curly braces that appear, you need to enter in text form a certain set of ordinary (available on the keyboard) characters.

For example, in order to get the expression square root of a million, you need to type in brackets: eq \r(;1000000) and press F9. In the future, the resulting expression can also be edited using the formula editor.

Graphic methods for writing special characters using Word.

You can draw a mathematical symbol yourself using the built-in “graphics editor” of Word. To do this, open the drawing panel and use a combination of lines and standard shapes to draw the desired sign. For example, to draw the square root you will need to draw only three segments.

If there is no button on the Word screen to expand the drawing panel, you can select it by clicking: View - Toolbars and checking the box next to the line "Drawing". So that you can print the required numbers under the resulting root sign, you need to configure the option "text wrapping" on "behind the text" or "before the text".

Schoolchildren or students nowadays often work in text editor"Word". However, due to lack of awareness, they are not able to perform some tasks in it. It is especially difficult to work with mathematical symbols, because there are not enough of them on the keyboard. This article will talk about the root sign. It will tell you how to insert it into your document. Four different methods will be demonstrated, and after reading the article, the user will decide for himself which one to use.

Using Microsoft Equation 3.0

It’s worth saying right away that this method for inserting a root sign into a document is excellent both for compliance with all standards and for applying it in all versions of the program. And we will use a tool called 3.0.

First you need to open the interface of the utility itself, for this:

Go to the "Insert" tab.
In the "Text" tool group, click the "Objects" button.
In the window that appears, select "Microsoft Equation 3.0", which is located in the "Object Type" list.
Click OK.

After this, a form to fill out will appear in the place where the cursor was placed. Please also note that appearance“Word” will change quite a lot.

To insert a root sign, you need to click on the “Fraction and Radical Templates” button in the “Formula” tool window. You can see its location in the image below.

Now you need to select the appropriate template. After this, a root sign will appear in the field for typing formulas, and next to it an empty cell in which you can enter a number. After the number has been entered, it will switch to standard interface programs by clicking left button mouse (LMB) outside the form for entering formulas.

Using the Formula tool

Newer versions of the program have a second option for entering formulas. It is understandable to the average user, but the document may not display formulas correctly in more earlier versions programs.

To enter the square root sign you need:

Click on the "Formula" button, which is located in the "Symbols" tool group.
In a special formula designer, find and click on the root symbol.

After that in special form To enter formulas, a root sign will appear. You can also enter a value there. However, using this method, the root will not stretch to fit the length of the entered data. To achieve this, you need to click on the “Radical” button in the same designer and select the required template from the drop-down list. All other actions are comparable to the previous method.

Using a symbol table

You have already learned how to put a root sign in Word with two in different ways, but there are two more on the way. However, the characters that are inserted will not stretch the top bar to accommodate the length of the input data.

To insert a root sign using the symbol table:

Go to the "Insert" tab.
Click on the "Symbols" button.
Select "Other symbols" from the list.
In the window that appears, find the desired symbol by highlighting it.
Click the "Insert" button.

After this, the root sign will appear as a regular symbol, and you can add the desired expression further.

Using a character code

If you tried to insert a root sign following the instructions above, you most likely noticed that the search takes quite a long time. Of course, after one use of this symbol it will be displayed in the “Recently Used” category, but there is still another option, less time-consuming, which will be discussed now.

To insert a character using a character code, firstly, you need to know its code, and secondly, know the hotkeys for converting it. So, the code for the square root symbol is: 221A. And the hotkeys for converting it are ALT+X. Now all you have to do is enter the code and press the hot keys.

You needed to write some technical text related to mathematics, and you wondered how to write symbols that are not on standard layout keyboards? For example, the root sign, which is also called a radical. You've probably noticed this designation on many websites. And this is not surprising, because even standard notepad able to display it. How to find the root on the keyboard? You will be surprised, but it is very simple!

Method No. 1. Use Alt key and number pad

To use this method, make sure that your keyboard has a number pad (on the right or combined with letters) and that the NumLock indicator is lit. If it is not lit, turn it on using the NumLock/NumLk key.

On laptops or compact keyboards, you may also need to hold down the Fn key; you can learn more about this from the instructions for your laptop. So, to type the root sign on the keyboard, you need to hold down Alt key and sequentially enter the numbers 2, 5 and 1 on the number pad, and then release the pressed key.

If you did everything correctly, a radical sign will appear on the screen. This is the easiest way to write a root on the keyboard. But what if you need the cube or fourth root? Unfortunately, this cannot be done in the same way, but it can be done in other ways, but they only work in the browser, when creating articles for websites. We'll talk about them a little below.

Method number 2. If your keyboard doesn't have a number pad

If it so happens that your keyboard does not have a number pad and there is no way to write the root on the keyboard using the first method - do not despair! You can also use any search engine and, by entering the “root sign” into it, you will get a symbol that can already be copied into your article.

If you do not have the Internet, then you can use the standard Windows application- symbol table. It's very easy to find. To do this, go to the "Start" menu, find the "Accessories" folder in it, and in it - the "System" folder. You can also press the Win+R key combination and enter charmap.exe in the field that opens and press Enter. This method applies not only to the root symbol, but also to others.

Method No. 3. Use decimal code (HTML code)

This method also does not require entering numbers with digital block. To add a square, cube or fourth root to your article in this way, you need to type these sequences of symbols and numbers on your keyboard:

√ - for square root;
∛ - for cube root

Method number 4. Use hexadecimal code (Unicode)

This method It is used extremely rarely due to its impracticality, but it would be a remiss not to mention it. Who knows when it will come in handy. If the site where your article will be located uses Unicode (although UTF-8 has long been widely used), you can use these sequences:

√ - for square root;
∛ - for cube root;
∜ - for a root of the fourth degree.

As you can see, there is nothing complicated in the question of how to find the square root on the keyboard. Now you know four ways to write it, as well as the cubic or fourth root.

Sometimes working with Microsoft documents Word goes beyond ordinary typing, fortunately, the program's capabilities allow this. We have already written about creating tables, graphs, charts, adding graphic objects and the like. Also, we talked about inserting characters and mathematical formulas. In this article we will look at a related topic, namely, how to put a square root in Word, that is, the usual root sign.

Inserting a root sign follows the same pattern as inserting any mathematical formula or equation. However, there are still a couple of nuances, so this topic deserves detailed consideration.

1. In the document in which you need to put the root, go to the tab "Insert" and click in the place where this sign should be.

2. Click on the button "Object" located in the group "Text".

3. In the window that appears in front of you, select “Microsoft Equation 3.0”.

4. The mathematical formula editor will open in the program window, and the appearance of the program will completely change.

5. In the window "Formula" click on the button “Fraction and Radical Patterns”.

6. From the drop-down menu, select the root sign you want to add. The first is the square root, the second is any other higher degree (instead of the “x” sign you can enter the degree).

7. After adding the root sign, enter the required numeric value under it.

8. Close the window "Formula" and click on an empty space in the document to go to normal mode work.

The root sign with a digit or number underneath it will be in a field similar to a text field or object field "WordArt", which can be moved around the document and resized. To do this, just pull one of the markers framing this field.

To exit the mode of working with objects, simply click in empty space document.

Advice: To return to the mode of working with an object and reopen the window "Formula", double-click with the left mouse button in the field in which the object you added is located

That's all, now you know how to add a root sign in Word. Master the new features of this program, and our lessons will help you with this.
