Microsoft Excel®

Coming to Excel

PAE Bird as Excel Functions

Use PAE Bird's math engine directly inside Excel cells — no app switching, no copy-paste. Solve, expand, factor, differentiate, and integrate as native spreadsheet formulas.

=PAE.SOLVE("x^2 - 5x + 6 = 0") =PAE.EXPAND("(2x-1)^3") =PAE.FACTOR("2x^2 + 6x + 4") =PAE.DIFFERENTIATE("x^3 + 2x","x") =PAE.INTEGRATE("3x^2","x")

PAE Bird Excel add-in — function results

All five PAE functions returning results live in Excel cells.

PAE Bird Excel — formula bar showing =PAE.SOLVE()

Native Excel formula syntax — type it just like any other function.

Generate Student and Teacher worksheets directly from the task pane.

Google Sheets™

Available as a Google Sheets™ Add-on

PAE Bird in Google Sheets™

Use PAE Bird's algebra engine as native Google Sheets™ formulas — solve equations, expand, factor, differentiate, and integrate right inside your spreadsheet. Powered by PAE Bird's cloud API; math expressions are processed securely and never stored.

Note: unlike the offline Mac app, the Google Sheets™ add-on sends formula inputs to PAE Bird's API to compute results.

=PAE_SOLVE("x^2 - 5x + 6 = 0") =PAE_EXPAND("(2x-1)^3") =PAE_FACTOR("2x^2 + 6x + 4") =PAE_DIFFERENTIATE("x^3 + 2x","x") =PAE_INTEGRATE("3x^2","x")

PAE Bird in Google Sheets — PAE_EXPAND formula bar

Results returned directly into Sheets cells. Formula bar shows the PAE Bird function.

PAE Bird in Google Sheets — PAE_FACTOR formula bar

All five operations available: solve, expand, factor, differentiate, integrate.

PAE Bird Google Sheets — native autocomplete showing all 5 functions

Native Sheets autocomplete surfaces all PAE Bird functions as you type.

LibreOffice
