Key ideas in Excel for Everyday Work
- Excel treats plain numbers and math symbols as literal text unless told otherwise
- Typing an equals sign (=) at the beginning of a cell tells Excel to evaluate it as a formula
- Pressing Enter calculates and displays the answer while storing the formula behind the scenes
- Referencing a cell address like A1 points to whatever value that cell holds right now
- When an input cell changes, Excel immediately recalculates any formulas referencing it
- Typing static numbers like =10+5 instead of cell references means you must manually retype the formula whenever inputs change
- The fill handle is the small square located in the bottom-right corner of an active cell
- Dragging the fill handle copies the formula into neighboring cells without manual typing
- Excel automatically shifts cell references row-by-row as you drag downward
- Writing long chains like =B2+B3+B4 is slow and prone to leaving out cells
- The =SUM() function adds an entire continuous range of cells specified with a colon like B2:B20
- =AVERAGE() calculates the mean of a range rather than the total
- Excel treats standard cell coordinates as relative to where the formula sits
- Moving or copying a formula down one row automatically increases row numbers by one
- Copying formulas across columns shifts the column letters instead of the row numbers
- A dollar sign before a column letter or row number locks that coordinate in place
