2. Spreadsheet A computer programme which contains data about things that you want to put in. The computer programme is usually called Microsoft Excel.

3. Worksheet A paper in which you keep data in or work done or in progress.

4. Cell In Excel, each rectangular box in a row is called a cell.

5. Row Rows can run horizontally in a worksheet. They are identified by a number in the row header.

6. Column Columns can run vertically in a worksheet. They are identified by a letter in the column header.

7. Formula Formulas in a worksheet are there in order to make calculations. Multiplying you use the * symbol. Dividing you use the / symbol. Finding the minimum of something you write =min(E1: E6) Adding you do =sum(D1 :D6) Average total is =average (C1:C6) Finding the maximum of something you write =max(C1: C6)

8. Function Like formulas, functions begin with the equal sign ( = ) followed by the function's name and its arguments. The function name tells Excel what calculation to perform. The arguments are contained inside round brackets.

9. Macro An Excel macro is a set of instructions that can be triggered by a keyboard shortcut, toolbar button or an icon in a spreadsheet.

10. Conditional Formatting A conditional format is setting a format on a cell that is based on a condition, normally a value in a cell.

11. Locking Cells There's pretty much just two reasons for locking cells: To restrict entry (locked cells may not be changed) To allow tabbing to different cells for entry (unlocked cells can be tabbed through) The points you should know are these: All cells are locked by default If you want most cells locked, then only unlock those you want users to be able to change If you want most cells unlocked, then unlock them all first, and then lock only those you want prohibit users from changing
