Use the DELTA function with 4 how-to topics, including entering the formula, checking syntax prompts, using nested or cross-sheet references, and confirming automatic updates.
How-to Index
How-to Guide
1. Enter the DELTA function for a basic calculation
Entry point: Formula tab → formula bar or target cell
- Open AirSheet and select the cell where you want to display the result.
- Type
=to start editing the formula. - Type
DELTA(. - Enter the first argument and the second argument, such as
DELTA(A2,B2). - Type the closing parenthesis and press Enter.
Success Criteria
- UI state: The target cell displays a calculation result.
- Next actions: You can copy the formula, fill it down, or edit the arguments.
Tips While Using
- Common mistakes: Missing parentheses, commas, or argument positions can cause a formula error.
- Environment limits: The arguments should be numeric values that can be compared.
2. Check the DELTA function syntax prompt
Entry point: Formula bar
- Select any blank cell.
- Type
=DELTA(. - Check the syntax prompt shown in the editing area.
- Complete the arguments based on the prompt.
Success Criteria
- UI state: You can see the function name and argument prompt.
- Next actions: You can continue entering the formula with the prompt as guidance.
Tips While Using
- Common mistakes: If you do not type the opening parenthesis, the prompt may not appear completely.
3. Use DELTA in a nested formula or across worksheets
Entry point: Formula tab → target cell
- Select the cell where you want the result to appear.
- Enter a combined formula that includes DELTA, such as using DELTA as part of a condition.
- If you need a cross-worksheet reference, enter the worksheet name and cell reference first.
- Check the formula structure and press Enter to confirm.
Success Criteria
- UI state: The cell returns the final result of the combined formula.
- Next actions: You can continue editing the outer function or adjust the reference range.
Tips While Using
- Common mistakes: An incomplete worksheet name can cause a cross-sheet reference to fail.
- Environment limits: If the formula is long, edit it in the formula bar so the structure is easier to review.
4. Check whether DELTA results update automatically
Entry point: A worksheet that already contains DELTA
- Find a result cell that already uses DELTA.
- Change the value in one of the referenced argument cells.
- Check whether the result cell changes accordingly.
- If it does not change right away, confirm that the formula reference range is correct.
Success Criteria
- UI state: The result updates when the referenced values change.
- Next actions: You can continue filling, copying, or counting results.
Tips While Using
- Common mistakes: If you edit a cell that is not referenced by the formula, the result will not change.
