Every spreadsheet calculation relies on accurately pinpointing where numbers are located. In spreadsheets, data is entered and referenced using systematic Cell Addresses.
A Cell Address (also called a Cell Reference) is formed by combining the Column Letter followed by the Row Number:
$$\text{Cell Address} = \text{Column Letter} + \text{Row Number}$$
A1: The intersection of Column A and Row 1 (The very first cell in any sheet!).C4: Column C, Row 4.AMJ1048576: The absolute bottom-right corner cell in a standard LibreOffice Calc sheet.A Range is a continuous group or block of adjacent cells selected together. A range is represented by the starting top-left cell address, a colon (:), and the ending bottom-right cell address:
$$\text{Range} = \text{TopLeftCell} : \text{BottomRightCell}$$
A1:A10: A vertical column range of 10 cells (from A1 down to A10).A1:E1: A horizontal row range of 5 cells (from A1 across to E1).B2:D6: A rectangular block of 15 cells (3 columns wide $\times$ 5 rows tall $= 15$ cells).When you type into a cell, Calc and Excel automatically detect the data type:
| Data Type | Description | Default Alignment | Examples |
|---|---|---|---|
| Text / Label | Words, names, descriptions, or alphanumeric codes | Left-Aligned (बाईं ओर) | Suresh, Roll-101, Lucknow |
| Number / Value | Pure numerical values used in mathematical calculations | Right-Aligned (दाईं ओर) | 450, 98.50, -25 |
| Date & Time | Calendar dates and timestamps | Right-Aligned (दाईं ओर) | 13/09/2026, 10:30 AM |
| Formula | Mathematical expression beginning with an equals sign (=) | Result is displayed | =A1+B1, =SUM(C1:C10) |
'), such as '98765, the spreadsheet will treat that number as Text and align it to the left!Enter: Confirms data entry and moves the active cell down to the next row.Shift + Enter: Moves the active cell up to the previous row.Tab: Moves the active cell right to the next column.Shift + Tab: Moves the active cell left to the previous column.Ctrl + Home: Jumps directly to the very first cell of the sheet (A1).Ctrl + End: Jumps directly to the last used cell in the worksheet.Continue learning with hands-on practice, examples, and exercises in the upcoming topic.
