2. Microsoft office excel 2010 Introduction:
Microsoft Excel Excel 2010 is an application program that provides a mathematical / statistical / logical environment. It provides a network of cells with their dimensions so that each cell retains one value with the possibility of applying functions or manually constructing complex functions on the contents of these cells to obtain the desired result.
The program also provides the possibility of filtering data to show only specific values / order of data / search to detect the existence of a specific value and perform the operations required to / link the values of cells together by links or link the content of the cell to another external file of another type.

3. CHAPTER 1: THE MAIN SCREEN
To run Microsoft Excel 2010 click :
Start < all program < Microsoft office < Microsoft Excel 2010 the following window will appear:

4. If you are familiar with the office 2003 program, you will notice the absence of drop-down menus, but do not get confused, the tapes will make it easier to operate than drop-down menus.
The main interface elements are:
1. Command Bar: Is a bar that contains many commands for easy access, and you can add / cancel commands by pressing the small arrow to the left of the bar and selecting More Commands, the many use commands (Back ،Print preview ،Save).
2. Ribbons: The lists of classified tools, each bar contains tools classified under the title of that bar.
3. Tools: Each icon within the bars represents a tool with an effect classified by the title of the bar in which the icon is located.

5. 4. The default work sheet address : Automatically, the new file will be under the name (Book1) If the file is stored in another name, the new name will appear in this location.
5. Workspace: A huge network of cells with invisible borders when printing, each cell can contain one specific value (number, code, text, date, etc). The cell is defined by a Latin character (representing the column), followed by a number (representing the line), for example : B12 ،HN1 ،D4
6. Pages: Each new work file contains three pages. Automatically, cells can be linked to different pages with links.

6. CHAPTER 2: Create a table
To enter a value in a cell, simply click on the cell and type the desired data.
To move to another cell, use the arrows in the keyboard, or click the pointer on the new cell.
If we write text longer than the length of the cell, we will notice that the text will hide under the adjacent cell. To enlarge the length of the cell in proportion to the length of the text, double-click the border between the two cells, or click on the border and drag to the right,

7. If we write a numerical number longer than the length of the cell, the number will automatically be converted to the scientific Exponential Form, for example: the number will be E+11.
To return the number to normal, place the pointer over the desired cell < right click < format cells < choose page number < choose number from the list< Decrease the value of the decimal places field to zero< OK as shown in picture:

8. If the number turn to it is enough to enlarge the cell length to return the number to its original image

9. To merge two or more cells, select the cells you want to merge by dragging the pointer over them < click home bar < click icon
To write multi-line text in a cell or range of cells, select the cells by dragging the pointer < click home bar < click icon
To choose a full line, a full column, or choose all worksheet:

10. To edit the text format, select cells< click home bar < Click the desired tool as follows:
To zoom in/zoom out visibility, you can drag the pointer located in the lower-right corner of the user interface

11. To move a cell or group of contiguous cells, shaded the desired area < Place the pointer on the selected group frame < Pull with the pressure to the new location:
To insert a row between two rows, click on the address (number) of the row that is located after the place where you want to insert a row < right click < insert . For example, if you want to insert a row between row 4 and row 5, you must place the pointer on row 5 and then perform the rest of the steps.

12. To insert a column between two columns, click on the address (letter) of the column that is located after the place where you want to insert a column < right click < insert . For example, if you want to insert a column between column 4 and column 5, you must place the pointer on column 5 and then perform the rest of the steps.
To delete a full line: Place the pointer on the desired line (number) < right click < delete.
To delete a full column: Place the pointer on the desired column (letter) < right click < delete.

13. To rename sheet, insert a new page to the work file, delete a page, move or copy a page, protect a page from edits (i.e add a password), change the page title color:
Place the pointer at the title of the page < right click < choose the edit you want.

14. To change the heading direction (make the page from right to left) < click the Page Layout bar < click icon (sheet from left to right ) , address will be reversed as shown:

15. CHAPTER 3: create series
If we wanted to fill a line of cells with numbers from 1 to 100 or fill these cells with natural marital numbers (2 , 4, 6,8,.....), It is not logical to fill each cell separately. Microsoft Office Excel provides a way to fill a row of cells with values related to a relationship (serial numbers, multiples of 5, names of the week, names of the year, etc.).
Examples:
1. To fill a row of cells with positive natural numbers (1,2,3,4,5,6,....), type the first value of the sequence in the first cell of the column < type the second value of the sequence in the adjacent cell < shaded these cells with the pointer < place the pointer on the small black box that will appear in the bottom right corner of the cells < Pull the pointer with pressure on the box, You will notice that the cells are automatically filled with the rest of the serial values> Stop when the final value is reached in the series.

17. Now, in the same way, you can fill the cells with any sequence by typing the first two values of the sequence and then letting the Excel program do the work for you. Example of serials:
(2,4,6,8,......) write 2 and 4 then pull with pressure.
(5 ,10 ,15 , 20 , .....) write 5 and 10 then pull with pressure.
H.W/
(2,4,6,8,......) write 2 and 4 then pull with pressure.
(5 ,10 ,15 , 20 , .....) write 5 and 10 then pull with pressure.
(0.0 , 0.1 , 0.2 , 0.3 , 0.4 , …….)
(-1 , -2 , -3 , -4 , ……)
(Sunday , Monday , Tuesday , …..)
(January , February , March , ……)

18. CHAPTER 4: create function
The program provides the possibility to create a function so that changing any of the input of this function will update the output function automatically without having to rebuild it. The program provides two methods to create a function:
Manually create the function:
Let us assume the following table, which represents the names of three students with their grades for three consecutive days:

19. To add a new column under the heading SUM, to find the total scores of each student:
Now to create the summation function manually:
Click the pointer on the cell to write the result inside (i.e, the F3 cell is in this example)
Type the plural equation in terms of cell addresses beginning with a ( = ) sign (i.e writing =C3+D3+E3
Press the Enter key. The result of the first student's collection will appear in the cell F3 as shown below:

20. d. Click on the cell F3 again < Place your mouse over the small black box that will appear below the right of the cell F3 < Press the pointer and drag down to the cell F5 < to fill the other cells with a total function sereis.

21. e. If any of the grades change, the total values will be updated automatically.
In the same way you can add another column to calculate the AVERAGE, where the equation will be used (and written inside the cell G3): =(C3+D3+E3)/3

22. 2. Using ready-made functions:
The program provides hundreds of mathematical, statistical, and logical functions such as AVERAGE , SUM , Conditional IF statement , MODE , STANDARD DEVIATION , MAX.
These ready-made functions are easy to apply, and all we have to do is feed them with the right inputs.
Let's re-apply the previous example to find the total student scores, but this time we'll use the ready function SUM
a. Press the pointer inside the cell where you want the output to be placed(F3 in this example ) as shown in picture:

23. b. Click on the format bar , You'll find folders that each have a label of ready-made functions, and as long as we want the sum function (mathematical), we'll click on the folder Math & Trig and choose SUM.

24. c. A new window will appear, click the upper red arrow, as in the picture:

25. d. The window will be clicked above and will look like this:

26. e. Select the cells that represent the inputs of function(i
e. Select the cells that represent the inputs of function(i.e cells from C3 to E3)
f. Press the input key twice, you will get the output in the cell F3

27. g. Click on the cell F3 again < Place your mouse pointer over the small black box that will appear below the right of the cell F3 < Press the pointer and drag down to the cell F5 < To fill the other cells with a total function sequence.
Exercise:
Create an average function by using the predefined functions of the same grades above

28. CHAPTER 5: save file
As mentioned previously, the new worksheet takes a default name book1, If you want to save the file, click the icon Located in the command bar The storage settings page shown below appears:

29. If we want to store the file again after making more changes to it, just click the icon again , The file will be updated with the same name.
If you want to store the file after the modifications under a new name (so that the original file remains unchanged) : click file < choose save as < The same storage settings page appears below, a new file name is selected and a click is pressed save.
