Spreadsheet - Primary function to perform calculations that may involve mathematical, financial, or scientific data.

--------------------------------------------------------------------------

__Typical Uses For Spreadsheets__

~ Budgets

~ Financial/Accounting Reports

~ Taxes

~ Students' Grades

~ Columns of Text

~ Graphs

**Excel** is the program we use to work with spreadsheets.

An Excel file consists of two parts: worksheets and workbooks.

**Worksheets** are the actual spreadsheets that contain the data in which you can organize and manipulate.

**Workbooks** are the entire Excel files. Workbooks can have multiple worksheets or as few as one. Each worksheet in a workbook will have a unique name that can be accessed on the tabs at the bottom of the screen.

__Parts of the Spreadsheet__

**~ **The vertical areas of the spreadsheet are **COLUMNS**; They are labeled A-Z, AA-AZ, BA-BZ, etc..., there are 16,384 Columns in MS Excel.

**~ **The horizontal areas of the spreadsheet are **ROWS**; Rows are labeled numerically; There are 1,048,576 Rows in MS Excel

~ The Rectangular area in which a row and column intersect in the workspace is called a **CELL**.

~** **The selected cell with the heavy border around it is called the **ACTIVE Cell.**

~ A description of which row and column intersect to form the cell is known as the **CELL ADDRESS**. Cell A1 is the address for the cell in the first row and first column. The correct way to name a cell location is Column then Row.

**~ **The area that displays the address of the active cell is called the **NAME BOX**.

**~ **The** Formula Bar **is the area that displays the contents of the active cell. You may edit your data here

Tip: When highlighting in a spreadsheet, the inside color of the first cell will be white.

__Spreadsheet Formulas__

* An instruction to calculate a number

* The formula is entered in the cell where the answer should appear

* After you hit the "Enter" key, the answer is displayed in the active cell while the formula remains visible in the formula bar

*The four math operations are: + for add; - for subtract; * for multiplication; / for divide

__Two Rules When Creating Formulas:__

~ A formula *always* starts with =

~ A formula uses cell addresses, not the values themselves. (This way, if the values in the cell locations change, the answer will automatically change.)

__Spreadsheet Functions__

* Built-in formulas that perform special calculations automatically.

- Sum functions add up a column of figures. (SUM)

- Average functions averages a group of numbers. (AVERAGE)

- Count functions count all the blank spaces in the range. (COUNT)

- Minimum functions indicate the lowest value in the range. (MIN)

- Maximum functions indicate the highest value in the range. (MAX)

- The IF STATEMENT is a logical function which sets up a conditional statement to test data. the truth or falsity of the condition will determine the results of the statement.

*Functions *always* start with =

*There are 3 parts of a function: 1) =

2) Function Name

3) Argument - The range of cells that the function affects and it lists inside parentheses, first cell : last cell

* Example: to add cells=B2 + B3 + B4 + B5 + B6 you could use the function:

=SUM(B2:B:6)
