10 logical values ​​of the expression operation. Boolean values, operations, expressions. Full and Incomplete Branching Programming

In the material "" the most complete way of replacing the background in a template with a picture was considered. As indicated, this option is not the fastest. However, if the presentation consists of different types of slides, then you need to use it, as you can better customize it. appearance background.

However, for general presentations, you can dramatically speed up the background replacement process. The main difference is the ability to replace in the main window of the program, without switching to the slide master mode.

How to quickly change the background in a presentation:

1. Calling "Background format".

A dialog box is called up. To do this, you need to right-click either on a free area of ​​the slide, or on any part of the slide thumbnail in the tab located on the left in the work area Microsoft PowerPoint 2010.

2. Choice of filling method.

There are several options for replacing the background in the presentation. These are different types of fills, and adding images. To add a picture as a background, select "Picture or Texture" and then "File".

3. Insert background

Across windows explorer you need to specify the desired picture and insert it on the slide. If it is assumed that this background option will be common for all slides in the presentation, then on the open "Format Background" window, click the "Apply to All" button.

Let's imagine the following situation: you are making a presentation, you have chosen a suitable theme for the design from the list, the required font for the text, but the background of the selected theme is not very suitable and I would like to change it. If this is a children's presentation - put bright balloons, if it relates to nature - choose a field with flowers and a lake, and if you represent the goods of any company - you can put its logo as a background.

In this article, we will look at how to make the background image you need in PowerPoint presentations, and how you can change the transparency of the picture on the slide that is selected as the background.

We will start with template changes in PowerPoint... This will be especially useful for those who plan to use the selected picture more than once as a background for various presentations.

Open the presentation and go to the "View" tab. Now in the group Sample Modes click on the button "Slide Master".

Select the first slide, right-click on it and select from context menu"Background format".

The corresponding dialog box will open. On the "Fill" tab, put a marker in the field "Pattern or texture"... You can choose one of the suggested textures as a background. The result will be immediately visible on the slides.

To make the background of the slide a picture that is stored on your computer, in the "Insert from" field, click on the "File" button. Using Explorer, find the image you want on your computer and click "Insert". The background of the slides in the presentation will change.

If you find a suitable image on the Internet, then you can also make this image a background for slides in PowerPoint. Opening the image in full size, click on it with the right mouse button and press "Copy". This way we will put it on the clipboard.

Back to dialog box"Background format" and click on the "Clipboard" button. The background in the presentation will change.

You can also choose any picture from the PowerPoint collection as a background. In the "Format Background" dialog box, click on the "Picture" button, then select one of the proposed images and click "OK".

After you select the desired image as the background for the presentation, click "Close". To return to the usual view for working with the presentation, on the "View" tab in the group Presentation View Modes click "Normal".

So, we have changed the template for the presentation. Now consider how save template with selected image as background in PowerPoint.

Go to the "Design" tab, expand the list of available themes and select "Save Current Topic".

The saved theme with the desired slide background will be available in the general list of themes. When creating a new presentation, you just need to select it.

If you need make a background for one slide in PowerPoint Using the selected image, select the desired slide with the mouse, right-click on the background and select "Format Background" from the menu.

Now select a picture or picture for the background of the presentation, as described above, and click "Close". Change the background only for the selected slide.

By pressing the button "Restore Background"- will return the old background for the slide by clicking "Apply to all"- the selected picture will be set as the background for all slides in the presentation.

To change the background, for example, only from the second to the fifth slide, select the second slide, press Shift and select the fifth. To select slides that are not next to each other, hold down "Ctrl" and select them one by one: 2, 3, 5. Click on any selected slide with the right mouse button and select "Format Background" from the menu. Then do everything as described in the article.

After you have made the desired picture as the background for the slides in the presentation, you may need to modify it a little. Let's figure out how you can do transparent background in PowerPoint and not only.

You can change the transparency of the background, picture or picture in the "Format Background" dialog box. Select the slides you want and open the specified dialog box. On the Fill tab, in the Transparency box, move the slider to the desired position.

You do not need to select all slides for the changes to be applied to them, after all the settings, just click "Apply to all".

In the tab "Picture Setting", you can change the sharpness, brightness and contrast. On the Picture Color tab, you can adjust the saturation and hue.

Making a picture or drawing a background in a PowerPoint presentation isn't too difficult. In addition, you can save the customized template with the desired background and use it in all subsequent presentations. If your image turns out to be too bright, change the transparency of the background so that viewers are not distracted by it and can normally perceive the information presented in the slides.

  1. When using the Format Background command, the program stretches the image to fill the entire slide. How can we reduce the size of the image by area, as if we were dragging a corner of the image? I need the image to fit into the template in size, otherwise it is large. I reduced the size of the image in FShop, but it still stretches to fill the entire sheet.

    To answer

It's no secret that the templates available for Microsoft PowerPoint for creating presentations do not always match the request. In this connection, it is worth figuring out how to make your background in a PowerPoint presentation from a picture yourself, spending a minimum of time on it. In this case, by drawings we mean a variety of pictures created with the help of editors, online, as well as photographs.

Inserting a picture into the background by adjusting the presentation template.

First of all, let's consider not the fastest way to change the background when preparing a presentation template. However, it is more correct if you need to reuse the result as a template, and not just make a one-time presentation.

With such a rework, it will be possible to see how new background is displayed on all variations of template layouts. The main advantage of this approach is the ability to timely change the location of parts of each slide if they do not fit well with the picture.

We will use PowerPoint 2010 for demonstration. The whole process, in general, is similar in other versions of the PowerPoint program - from 2007 to 2016.

1. Slide Master

Select the VIEW tab, then in the SAMPLE MODES group click on the SAMPLE SLIDES button.

2. Background format

Right-click on the first slide of the presentation and select the background format.

3. Fill

In the BACKGROUND FORMAT tab that opens, in the FILL mode, select the PICTURE OR TEXTURE. You will notice that the slide background in the template will automatically change to the default texture.

4. Textures

If we want to insert a background from the existing texture of the PowerPoint program, then using the TEXTURE button we select a background picture from the proposed ones.

5. Insert a picture

There are several options for inserting a picture - from a file, from the clipboard, from the organizer (picture)

    • From a file. Click on FILE and select the desired picture on your own computer.
    • From the clipboard. This option is most convenient if you are looking for a background for presentations on the Internet. Let's see how you can do this. Launch images.yandex.ru and enter into search string"background for presentation". The number of backgrounds on offer is enormous. You can immediately copy the image to insert the background, but it is too compressed, and the quality of such a background will not be very high.

For more High Quality background you need to go to the image and then just copy it using the menu right button mice. You can also download the image to your computer and then insert it via FILE.

Return to the PowerPoint presentation you are creating and click CLIPBOARD. The copied image is pasted and the background for your presentation is created.

  • PowerPoint's own organizer is also a good resource for creating a background from a picture. So, we press the PICTURE button and look for a suitable one, including the Microsoft site.

A template with a new background for presentations can be saved by choosing the "PowerPoint Template" format when saving as a TYPE OF FILES.

You will notice that when you work on the first slide, the background of the entire presentation changes. If you need to change the background of an individual slide, then all these actions need to be performed with it. Then all other slides in your PowerPoint presentation will remain unchanged. So you can, if you wish, make your own background for each.

A quick way to add your own background image

The second option is to make the background from the image easier, faster and in most cases sufficient. For the sake of completeness, we will be working with Microsoft PowerPoint 2013.

How to change the transparency of a background, picture, or picture in PowerPoint

It happens that the drawing you have chosen is too bright. This can negatively affect the perception of information on the slides and the presentation itself as a whole. This means it is necessary to reduce the saturation of the pictures.

Right-click on an object, then through the same BACKGROUND FORMAT, if the picture has previously filled the entire space. Or PICTURE FORMAT, if to create a background it is enough just to insert a picture in some part of the presentation slide without changing the background.

Then FILLING - DRAWING AND TEXTURE. Find the TRANSPARENCY slider and move it to the right. This will make the picture, drawing, slide background more transparent in PowerPoint.

Changes are visible as you move the slider or change the transparency percentage numbers to the right.

Logics(from the Greek "logos" meaning "word" and "meaning") - the science of the laws, forms and operations of correct thinking.

Its main task is to find and systematize the correct ways of reasoning.

Now we need some definitions.

ALGEBRA OF LOGIC - branch of mathematical logic studying the structure of complex logical statements and ways to establish their truth using algebraic methods.

OBJECTS studying the algebra of logic: STATEMENTS

A logical statement is a declarative sentence in which something is affirmed or denied and about which it is possible to unequivocally say whether it is true or false.

Not every statement can be a statement. For example, the following statement: "Malachite is the most beautiful stone of all known gems" a statement cannot be, since it is a matter of taste.

III. Learning new material - 17 min.

Exercise 1.

Which of the sentences are utterances? Determine their truth?

1. Paris is the capital of England. (LYING)

2. Listen to the message.

3. Who is missing?

4. The number 11 is prime. (TRUE)

5. Name the information input device.

6.4 + 5 = 10. (LYING)

7. You can't get a fish out of a pond without difficulty.

8. Some bears live in the north. (TRUE)

9. Add the numbers 2 and 5.

Statements

General

Private

Single

They begin with the words: everyone, everyone, everyone, not one, any ... All fish can swim

They begin with the words: some, most, many ... Some bears are brown

All other cases The letter A is a vowel.

There are statements that are true or false that cannot be verified. For example: "There is currently one and only one tree on planet Earth with exactly 10,000 leaves." Theoretically, it is possible to verify this, but only theoretically, since for such a test it will be necessary to use too many inspectors, much more than there are people on the planet.

Thus, mathematical logic studies only statements, and only how to determine their truth or falsity.

Mathematical logic does not investigate the meaning of statements, from which it follows that the formulation of the statement does not play a role and for the statement it is enough to introduce a simple notation.

Boolean variable is a simple statement containing only one thought. Her symbolic designation - Latin letter.

The value of a boolean variable can only be the constants TRUE and FALSE (1 and 0).

Complex statements. Logical operations

Earlier, we talked only about simple statements, statements can also be complex, consisting of several simple ones. connected by a logical link AND, OR, NOT

For example, a Difficult utterance:

"The number 6 is divisible by 2 and the number 6 is divisible by 3"

"In the summer I will go to the village or on a tourist trip"

"The number 4 is not divisible by 3"

(over the first sentence we stick A and B)

(over the second sentence, stick A or B)

(over the third sentence we stick not A)

In the first example, a complex sentence is constructed from two simple ones using logical operation- conjunction A ^ B,

in the second - AVB disjunction

in the third - negation

Conjunction (logical multiplication).

It is expressed by the union of I.

It is denoted by a sign (^ or &).

Written A ^ B

The value of such an expression will be FALSE if at least one of the operands is false.

Disjunction (logical addition).

Expressed by the union OR.

Indicated by a sign (V).

Recorded A V B

The value of such an expression will be TRUE if at least one of the operands is true.

Inversion (negation)

Expressed as a NOT particle.

It is indicated by a sign (-).

Written -A

The value of such an expression will be FALSE if the value of the operand A was true and vice versa.
