I would also like to start with a larger figure, and as I enter a smaller figure have the answer automatically subtract.
Math is a formula editor, not a calculator. Use Calc for calculations. “=343-76” automatically calculates and displays the result.
Only what’s after ‘calculations.’ was needed. Don’t understand (the need for) everything before “=nnn-nn”. I used that and got the difference I was after. So thanks for that bit…
