**Active Cell**- Cell into which any text or numbers that are entered will be placed.
**Cell address**- Name of cell, taken from the column letter and the row number, e.g.
**B4**which is column B, the 4th line. **Cell**- A rectangle in a spreadsheet.
**Chart**- A graph based on selected cells in a spreadsheet. There are many types of charts.
**Column**- A vertical line of cells, indicated by a letter.
**Formula**- A statement that uses cell addresses and/or numbers and mathematical signs to designate a calculation. The result of the calculation is placed in the cell where the formula is created.
**Numbers**- Constant values in a cell. Numbers can consist only of the characters 0 1 2 3 4 5 6 7 8 9 _ + / . E and e. If a numerical entry is too large for the physical viewing size of a cell, or if the result of a formula is too large you may see a group of "#"symbols, e.g. ##########. Make the column larger to see the full number by dragging the right column line. Or you may see a scientific number, e.g. 23423E+11 instead of the 234234234234 that you entered.
**Numerical formats**- The way that the numbers appear in the cell(s). Formatting choices include currency (adds a $ and two decimals to all numbers in the formatted cell(s).), percentage (adds a % and in a formula automatically treats the number as part of 1, e.g. 86% will be treated as 0.86).
**Range of cells**- A group of cells that you wish to treat as a group, may be contiguous as for example, cells C1 to E3 in table 7-4. Can also be noncontiguous. A range of cells can be named.
**Referenced Cell**- A cell that is included in a formula in another cell. This cell may be in the same worksheet, another worksheet in the same workbook, or in another workbook.
**Row**- A horizontal line of cells, indicated by a number.
**Text**- Any non-numerical entry. If a cell contains only numbers the data in that cell will be treated as if it were a number unless preceded by an apostrophe (').
**Workbook**- Collection of related spreadsheets that are saved as one file.
**Worksheet**- One spreadsheet in a workbook.
