4 1. Place the cursor in cell A1. 2. Type John Jordan. Do not press Enter at this time.

5 The Backspace key erases one character at a time. 1. Press the Backspace key until Jordan is erased. 2. Press Enter. The name "John" appears in cell A1.

6 After you enter data into a cell, you can edit the data by pressing F2 while you are in the cell you wish to edit. Change "John" to "Jones." Move to cell A1. Press F2. Use the Backspace key to delete the "n" and the "h." Type nes. Press Enter.

9 Document Excel presents itself book, consisting of separate sheet. The Tag three sheets are seen left of horizontal band of the rolling. In total sheets can be 255 " Workspace window is under the table, consisting of column and lines, on intersection which are found cells. The Column named letter Latin alphabet or their combinations, there are 256. The lines are designated from 1 to 65536

10 Each cell has an address, consisting of name column and number of the line. The Address be relative, absolute and mixed. Addressing on method left, right, below, above - is identified to be Relative. The relative address will be automatically change The absolute address doesn't change where we wouldn't move it. For indication of the absolute address is used sign $. The mixed addresses is half relative and half absolute The Address of the cell possible to assign four ways: A1, $A1, A$1, $A$1.

11 A1 - a relative address $A1 and A$1 - a mixed address $A$1 – absolute address Change addressing in formula possible by key F4.

12 Formula is the symbols beginning with an equal-sign. These symbols can include constant values, links to cells, names, functions or operators Functions in Excel are used for performance of standard calculations in workbooks. Values which are used for functions evaluation are called as arguments. Values of functions as the answer are called as results. For convenience of work of function are broken on categories: mathematical, logical, statistical, text, financial and others.

13 " numeric (the number with specified by amount decimal sign) " money (with additional sign of the money unit - can be R (the rouble), TG (тенге), $ (the dollar) and etc.) " date (with instruction of the type writing the date - a month by numeral or name) percent (with symbol %) " fractional (in the manner of simple crush ?, 21/25, ) " exponential (in the manner of 5,7Е+03 i.e. 5,7 103) and etc.

14 Read the text once very attentively and try to understand and remember as much as you can

18 The Formulas present itself expressions, on which are executed calculations on page. The Formula begins with equal sign (=). Is it Below cited an instance formulas, multiplying 2 on 3 and adding to result 5. =5+2*3 The Formula also can include the following elements: functions, references, operators and constants.

19 In Microsoft Excel, you can enter numbers and mathematical formulas into cells. Whether you enter a number or a formula, you can reference the cell when you perform mathematical calculations such as addition, subtraction, multiplication, or division. Use the following to indicate the type of calculation you wish to perform: + Addition - Subtraction * Multiplication / Division ^ Exponential

20 You can use the AutoSum button on the Home tab to automatically add a column or row of numbers. When you press the AutoSum button, Excel selects the numbers it thinks you want to add.
