I was about to say manual/auto recalc.
another one is Text v general formtting, but the cell would show the formula rather than calculate - but it can be disconcerting if you haven't sussed it.

FWIW if you want to leave formatting as general, you can precede text with a single quote "'" and it will treat it as text which is handy for arithmetic operators that you want to show as text - like the dash.
