How-to Guide

1. Enter the GAMMAINV function

Entry point: Formula tab → formula bar

  1. Open AirSheet and select the cell where you want to enter the formula.

  3. Continue by typing GAMMAINV(.
  4. Review the syntax prompt that appears and prepare to enter the arguments.
  5. Press Enter to confirm and display the calculation result.

Success Criteria

  • The cell contains a complete GAMMAINV formula.
  • The result area shows a calculated value or an editable formula.
  • The formula bar remains available for argument changes.

Tips While Using

  • Start the formula with =.
  • Keep the opening parenthesis after the function name and close it correctly.

2. Fill in arguments with syntax prompts

Entry point: Select the target cell → type =GAMMAINV(

  1. Type =GAMMAINV( in the cell.
  2. Check the syntax prompt shown by the app.
  3. Enter the required arguments in order.
  4. Confirm that separators between arguments are correct.

Success Criteria

  • The syntax prompt displays the expected argument guidance.
  • The formula does not show obvious parenthesis or separator errors.
  • The cell returns a result or a recognizable error message.

Tips While Using

  • The number and type of arguments should match the function requirements.
  • If an error value appears, first check parentheses, commas, and argument content.

3. Reference arguments across worksheets

Entry point: Target cell → formula bar

  1. Select the cell where the result should appear.
  2. Type =GAMMAINV( and begin editing the formula.
  3. Switch to another worksheet and select the cells you want to reference as arguments.
  4. Return to the current formula and complete the remaining arguments and closing parenthesis.
  5. Press Enter to generate the result.

Success Criteria

  • The formula includes cross-worksheet references.
  • The result changes when the referenced arguments change.
  • The current worksheet displays the calculation result normally.

Tips While Using

  • Confirm that referenced cells contain valid values before using cross-sheet references.
  • Text-formatted numbers may affect the result.

4. Combine GAMMAINV with other formulas

Entry point: Target cell → formula bar

  1. Select the cell where you want to output the result.
  2. Enter a combined formula that includes GAMMAINV.
  3. Add other functions or cell references as needed.
  4. Check the parenthesis structure and argument order.
  5. Press Enter to view the final result.

Success Criteria

  • The combined formula is recognized correctly.
  • The result updates automatically when related data changes.
  • The formula bar still shows the full nested structure for review.

Tips While Using

  • For longer formulas, edit in the formula bar.
  • If the result looks incorrect, check each layer of the nested formula step by step.
