Spreadsheets A computer program used chiefly for accounting, in which figures are arranged in the rows and columns of a grid. Spreadsheets are used mostly for math calculations and some basic database functions and for creating graphs and charts.

Worksheets A worksheet is an object in a spreadsheet program that consists primarily of a grid of cells, organized in rows and column, in which spreadsheet calculations and information are held. A file saved by a spreadsheet program may consist of many worksheets.

Cell A memory location in a spreadsheet identified by its row and column coordinates and that is used to store labels, numbers, formulas, or instructions.

Row In a spreadsheet the ROW is defined as the horizontal space that is going across the window. Numbers are used to designate each ROW'S location.

Column A column is the vertical, up and down, group of boxes. Those boxes are called cells. The group of boxes that go left and right are called rows.

Formula Formulas in spreadsheet programs such as Excel are used to perform calculations. Formulas can range from basic mathematical operations - such as addition and subtraction - to complex engineering and statistical calculations. In programs such as Excel, Open Office Calc, and Google Docs Spreadsheets, formulas begin with an equal ( = ) sign and, for the most part, they are entered into to the worksheet cell(s) where we want the results or answer to appear.

Formulas

Function Function can be used for calculations in a spreadsheet. A simple example of a function is for adding a column of numbers. EXAMPLE: You have a column of 23 numbers in column B, from row 1 to row 23. To add all of those numbers, and display the results in cell B24, enter =SUM(B1:B23) in cell B24.

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. Macros are used to eliminate the need to repeat the steps of common tasks over and over.

Conditional Formatting Adding conditional formatting to a cell in Excel allows you to apply different formatting options, such as colour, to a cell or cells based on the data in the cell(s).

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)
